12 Core Bundle Pigtail

Pigtail known as pigtail cable, only one end of the connector at the other end is the core of the breakage of a fiber optic cable, connected by welding, and other fiber optic cable core, often appear in the fiber optic terminal box patch panel is used to connect fiber optic cable fiber optic transceiver (also used in the coupling, jumpers, etc.).

Divided into multimode pigtail single-mode pigtail pigtail: multimode pigtail orange, a wavelength of 850nm, the transmission distance is 500m-2KM, for short-range connectivity. Single mode pigtail is yellow, there are two wavelength 1310nm and 1550nm, transmission distance of 10km-40km and 40KM-120KM.

Fiber splicing technology:
Fiber splicing technology Splice machine to connect the optical fiber and optical fiber or fiber pigtail fuse together into a whole, the bare fiber optic cable and optical fiber pigtail, the pigtail is a single optical fiber head. Connected to fiber optic transceivers, fiber optic and twisted-pair connections, received the information outlets. The main tools used in fiber optic fusion process: the light side boxes, fiber optic transceivers, pigtails, coupler, special wire stripper, fiber cutter.
Transmission system commonly used with pigtails SC / PC, FC / PC, the LC / PC ST / PC four interfaces.

Said pigtail connector marked, we can often see the FC / PC, SC / PC, etc., its meaning is as follows:
"/" The front part of the pigtail connector models.
The SC connector is the standard rectangular connector, engineering plastics, high temperature, not easily oxidized advantages. Transmission equipment sidelight interface for general use SC connectors.
"LC" connectors and SC connectors are similar in shape, smaller than the SC connector.
FC connector is a metal connector, usually used in the ODF side, pluggable metal joints more often than plastic.
More varieties signal connector, in addition to the three described above, as well as MTRJ, ST, MU, and so on.

"/" Followed by that fiber connector cross-section process, ie, polishing.
"PC" in the equipment of telecom operators is the most widely used, the joint cross-section is flat.
UPC attenuation is smaller than the "PC", generally used for devices with special needs, some foreign manufacturers ODF frame internal jump fiber with the FC / UPC, mainly to improve the indicators of the ODF device itself.
In addition, more applications in CATV broadcasting and early "APC" Model Pigtail head with the inclination of the face, can improve the quality of television signals, mainly due to the TV signal is analog optical modulation, when the connector coupling the surface is perpendicular to the reflected light returns along the original path. The fiber refractive index profile of uneven will again return to the coupling surface, although the energy is very small but because of the analog signal can not completely eliminate the noise, so the equivalent of a clear signal superimposed on a weak signal with a delay performance is ghosting on the screen. Pigtailed headband angle allows the reflected light returns along the original path. General digital signal there is generally no problem.

What Is The Fiber Optic Adapter?

The Fiber Optic Adapter is an interface converter, it can be a stand-alone hardware interface devices allow connected to the hardware or electronic interface with other hardware or electronic interface, the information interface. Such as: power adapter, tripod base adapter parts, USB and serial port adapter equipment and so on.

In the computer, the Flange Fiber Optic Adapters is usually built-in can be inserted into the card slot on the motherboard (external) ... to be exchanged between the card in the adapter and the processor and adapters supported devices.
The power adapter is the supply of small portable electronic devices and electrical and electronic power conversion equipment, generally by the shell, the power transformer and rectifier circuit according to the output type can be divided into the AC output and DC-output type; can be divided according to the connection wall mount and desktop. Mobile PC battery power adapter to its particularly important.

The majority of mobile PC's power adapter can automatically detect the 100 ~ 240V AC (50/60Hz). Basically all mobile PC regarded the external power supply, connected with a line and host, which can reduce the size and weight of the host, only a handful of models to power built into the host. On the power adapter has a nameplate marked with the power of the above, enter the output voltage and current indicators, with particular attention to the input voltage range, which is the so-called "Travel power adapter.
When the MBean registered with the MBean server, you need to with these the MBean interoperability agreement, and requests from management applications to retrieve information. This is enabled through the protocol adapter, which will manage the application data is converted to a standard protocol information.

Multi-protocol proxy support protocol adapter include: SNMP, TL1, the RMI, CORBA, HTTP and HTML adapter.
In the actual development process, we often encounter such a thing, we developed based on the initial demand for a base class, learned of the detailed requirements in the development process or demand changes. Interface development work had already been defined, and has been massive investment in the coding. At this point, if the changes to the definition of the interface will cause a lot of coding on the repeatability of the adaptation process, and thus may result in semantic errors or logic errors caused by the changes do not fully Semantic errors can still be found at compile time, in the event of a logical error, the consequences will be very serious, or even enough to cause a system crash. At this point you need to use the design of the adapter pattern.

In computer programming, the adapter mode (sometimes also known as package styles or packaging) an interface adapter into the user would expect. Allow an adapter is usually because of incompatible interfaces can not be together the work of the class work together, the approach is the class's own interface wrapped in a class.
Mode is mainly used in the adapter, when the method defined in the interface unable to meet customer demand, or conflict with the name of the method or methods defined in the interface interface with customer demand.
Adapter mode to use:
Inherit the interface of a class at the same time, and known to use methods and properties of the known classes defined interface definition (using mainly a way to override the interface method). Such as the base class of other business, this class adapter interface, and known. Known class changes, simply modify the class adapter, to meet the implementation of the interface.

How To Solve The Pigtail Failure

Pigtail coiled caused by poor optical receiver no output

Analysis and Maintenance: Remove the fiber pigtail from the optical receiver pigtail head power meter measurement, the measured optical power is-1.3dB, this line distance is about 2.7km (per kilometer loss of 0.3dB)there is also a splice loss of 02dB, normal output pigtail. Turn on the power of the optical receiver, then access pigtailed optical receiver, the Signal Level Meter measured the optical receiver output is 98dB normal wear light output in the receiver cover not open the optical receiver lid pigtail no well plate, resulting in part of the pigtails pressure on the lid of the optical receiver crevices, resulting in no light power input to the optical receiver, re-plate a good pigtail, optical receiver back to normal, troubleshooting .

Pigtail head cleaning, resulting in the optical receiver output signal level is low

Analysis and Maintenance: The optical power meter to measure tail-4.5dB (cable optical power standards for 0-3dB), and then the Signal Level Meter the Metering receiver output signal level is about 48dB, is obviously not normal. Examination revealed a pigtail connecting the optical receiver of light dust, dirt, cotton ball with alcohol to wipe clean dust and dirt of the pigtail head, the then pigtail received optical receiver, and the Signal Level Meter measured the optical receiver output 98dB normal troubleshooting.

Overhaul Summary: The cause of the failure of these two cases is caused by the maintenance staff, careless in the connection of the pigtail and optical receiver in the repair process should pay attention to the end of the suspect's coiled correctly, pigtail less than 2cm in diameter bend, it will cause a greater attenuation. In addition, the connection must ensure that the pigtail head clean, so as to avoid failure.

Pigtail and poor fiber splicing, resulting in the optical receiver signal turtle output

Analysis and Maintenance: the face of this failure, first check the front-end optical transmitter and optical splitter is normal, if normal, check the optical node is normal, because this fiber optic cable distance of 2.7km. There are two splices. Pigtail head power meter measurement, found that the line failure, with OTDR measurements, measured at the 2.4km around the local failure in the front-end optical splitter. Because the first splice has passed, we can conclude that the fault lies between the fiber and pigtail. View and then weld the box fiber pigtail contacts are connected. Look contacts weld, but poor welding. Resulting in no light power output, call off the welding point, re-use of automatic welding machine for fiber and pigtail splicing. Welding a good measurement of contact loss is 0.2dB, normal. Using the power meter measured the optical transmission link loss is-1.4dB, normally, and the fiber pigtail box fasten, then pigtail connects to the optical receiver. Signal Level Meter to measure the optical receiver RF output signal level is 98dB normal optical receiver back to normal work and troubleshooting.

What is OTDR And How To Use?

OTDR (OpticalTimeDomainReflectmeter) OTDR Optical Time Domain Reflectometer (OpticalTimeDomainReflectmeter) is short for Optical Time Domain Reflectometer test of its fiber has a non-destructive, single-ended intervention, intuitive and fast unique advantages. With OTDR optical fiber testing can be divided into three steps: parameter setting, access to data and curve analysis. Manually set the measurement parameters including wavelength selection, and pulse width settings, measuring range, the average time.

(1)Select the wavelength: due to the different wavelengths corresponding to different light enamel reactor characteristics, general test wavelength should follow the principle of corresponding to the communication system transmission wavelength, that is open 1310nm wavelength, the test wavelength of 1310nm.

(2)Set the pulse width: the longer the pulse width, the greater the dynamic range, the longer the distance measurement, but have a greater test blind, short-pulse injection test short distance, but can reduce the blind spot.

(3) Measuring range: OTDR measurement range refers to the OTDR to obtain the maximum distance of data sampling, the choice of this parameter determines the size of the sampling resolution, the best measurement range of about 1.5 times the length of the fiber under test.

(4) The average time: Due to the scattered light signal is extremely weak, the general use of statistical averaging method to improve the signal to noise ratio, the average of the longer signal to noise ratio the higher the The general idea of the fault location in optical transmission systems: the first external, after the transfer. That is the fault location, first rule out the possible factors of the external, such as broken cables, power outages, and then consider the transmission equipment.Therefore, how to accurately locate the point of failure significant cause live Chui plug ring suck, resulting in displacement of lower. Lower the temperature, we can solve the problem.

Here we must note two points: (1) the environmental temperature is not high, does not exceed 40 ℃. (2) If the valve leakage, high temperature exhaust gas will return to the cylinder. At this time we should carefully check valve grinding disc or replace the valve, to eliminate air leaks, it was possible to solve the ultra-high temperature. Changde Ling Park Hunan oil-free air compressor air compressor for each field, to dusting pile driver, live Chui plug no oil, oil air compressor, screw air compressor, shotcrete, air compressor machine equipment, sand blasting anti-corrosion, fully equipped production facilities, manufacturers of direct leasing, and construction.

Test And Measurement Equipment For Fiber-Optic Network

1, Fiber Optic Identifier

It is a very sensitive photodetectors. When you will be a fiber bending, some light radiation from the fiber core. The light will be detected by the fiber identification, technical staff according to these light can be a single fiber in the multi-core optical fiber or patch panel identified from the other fiber out. Optical Fiber Identifier can detect the status and direction of the light does not affect the transmission. In order to make this work easier, usually at the sending end to the test signal modulated into 270Hz, 1000Hz or 2000Hz and injected into a specific fiber. Most of the optical fiber identifier for the operating wavelength of 1310nm or 1550nm single-mode fiber optical fiber, optical fiber identifier can use the macro bending technology to identify the direction and power of the transmission fiber and the fiber under test online.

2, the fault locator (fault tracking)

This device is based on laser diode visible light (red light) source, when the light injected into the fiber, if fiber fracture, connector failure, bending over, poor weld quality failure by launching the light of the fiber to fiber fault visualization positioning. Visual Fault Locator launched a continuous wave (CW) or pulsed mode. The typical frequency of 1Hz or 2Hz, but can also work in the kHz range. Usually the output power of 0dBm (1mW) or less, the working distance of 2 to 5km, and to support all the common connector.

3, optical loss test equipment (also known as optical multimeter or power meter)

To measure the loss of a fiber link, you need to launch the calibration stability of light at one end, and read out the output power at the receiving end. Both devices constitute the optical loss tester. The light source and power meter synthetic set of instruments, often referred to as the optical loss tester (also known as optical multimeter). When we measure the loss of a link, you need a test light source at the sending end operations while another person to use optical power meter to measure at the receiving end, this can only be drawn in one direction on the loss.

Typically, we need to measure the losses on both directions (because of the existence of the connection loss or that is due to the asymmetry of the transmission loss). At this time, the technical staff must be mutual exchange of equipment and then the other direction of measurement. However, when they separated by more than 10 floors, or dozens of kilometers, how to do it? Obviously, if two individuals each have a light source and an optical power meter, then they can be on both sides simultaneously measure now used for certification testing of advanced fiber-optic test kit can be bi-directional dual wavelength testing such as: the CertiFiber in Fluke 'and the DSP cable test series FTA fiber test package.

In short, to complete an optical loss measurement, a calibration light source and a standard optical power meter is indispensable. Reproduce from http://www.fiber-optical-networking-products.com/

Talking About The Development Status Of Fiber Optic Cable

The Ordinary Fiber Optic

the ordinary single-mode fiber is the most commonly used fiber optic. With the development of optical communication systems, optical repeater distance and a single wavelength channel capacity increases G.652.A optical fibers, there may be further optimized, the performance in the low attenuation coefficient of the 1550rim District has not been fully utilized and fiber minimum attenuation coefficient and the zero dispersion point is not in the same region. The cutoff wavelength of the meet the ITUTG.654 provisions displacement single-mode fiber and dispersion-shifted single-mode fiber G.653 provisions to achieve this improvement.

Core network fiber optic cable

China has in the trunk (including the full adoption of the national trunk, the province of the trunk and regional trunk) fiber optic cable, multimode fiber has been eliminated, all the single-mode fiber, including G.652 fibers and G.655. G.653 fiber in our country has adopted, but will not develop in the future. G.654 fiber optic because it can not significantly increase the capacity of fiber optic systems, have not used it in China's terrestrial fiber optic cable. The trunk cable using discrete fiber, optical fiber ribbon. The trunk cable is mainly used for the outdoors, these cables have been used sleeve Stranded skeleton structure, the current has stopped.

Access network, fiber optic cable

Short distance from the fiber optic cable in the access network, multi-branch and drop frequently, in order to increase network capacity, is to increase the fiber count. Pipeline in the city, due to limited pipe diameter, at the same time to increase the number of fiber core to increase the fiber optic cable fiber container density, reducing the cable diameter and weight, is very important. Access network using G.652 single mode fiber optic and G.652.C low water peak single-mode fiber. The low water peak single-mode fiber for dense wavelength division multiplexing, in China has a small amount of use.

Indoor fiber optic cable

Indoor fiber optic cable is often required for the transmission of voice, data and video signals. And the head may also be used for telemetry and sensor. International Electrotechnical Commission (IEC) referred to in the fiber optic cable classification of indoor fiber optic cable, I believe that should include at least Bureau of cable and wiring of two major fiber optic cable. Office cable laying on the central office or other telecommunications room, laying close orderly and relatively fixed position. Integrated wiring cable laying on the client's indoors, mainly by users, and therefore its vulnerability should be higher than the fiber optic cable more rigorous consideration.

Communication cable power lines

The fiber optic is a dielectric fiber optic cable can also be made ​​to all media, no metals. This all-dielectric fiber optic cable will be the power system the best lines of communication. For all dielectric fiber optic cable laid by the power poles Road, there are two structures: All Dielectric Self Supporting (ADSS) structure and for the overhead ground wire of the winding structure. ADSS fiber optic cable because you can separate deployment, wide, has been widely used in the current transformation of China's electric power transmission system. China has been able to produce a variety of ADSS fiber optic cable to meet the market needs. However, the product structure and performance, such as ambition the number of cable structure, cable creep and arc resistance properties, as well as to be further improved. The recent demand of the ADSS fiber optic cable in the country, is a popular products.

Fiber Optic Tool

When you use optical cable, you may need some tools that will support you in dealing the work. There are various types of fiber optic tool being used in the fiber optic installation and maintenance works. Fiberstore provide a wide range of hand fiber optic tools and tool kits. These tools and the work of the fiber, so they should provide support for people who work as the installation or repair work. Here are introduce several Fiber Optics.

First, Network Cable Tester is a kind of convenient and comprehensive tool for network professionals, they are always being used to test LAN Datacom and Telecom cables. It find all problems associated with testing such faults as opens, shorts, cable integrity and it also find cable length of individual cables or distance to a fault, and its powerful and user-friendly features enable network installers to accurately check pin configurations of various voice and data communication cables.

The second tool is Telephone Line Tester. Telephone Line Tester is a new kind of line fault tester with safety & multi-functions capabilities. Besides the functions as a common Tel Line Tester, it also has the functions of high voltage protection and dangerous voltage warning.A phone line tester is used for detecting either digital or analog phone systems as well as the line polarity. Telephone line testers are good for both personal and professional use. Fiberstore supply some mini phone line tester,and other Telephone line tester.

Crimping Tool will be the third important thing you need to provide. Fiber optic crimp tool is a tool designed to crimp or connect a connector to the end of a cable. For example, network cables and phone cables are created using a crimping tool to connect the RJ-45 and RJ-11 connectors to the end of the cable. It can bend, cut, strip and crimp insulated wiring in a snap. For cable and phone installation specialists, a handy crimp tool can cut and strip electrical wiring in a few seconds. FiberStore supplies a wide variety of specialized crimping tools which are all at a very competitive price to help you get the job done right.

Other miscellaneous tools are razor. This is a very handy tool when you need to be stripped from the wire insulation. Then you might also need the fiber cutting machine, because some type of cable contains glass or plastic wire instead of metal one.

You have to pay attention to electrical work, including fiber optic, and sometimes it is very dangerous. Therefore, the provision of supporting tools to help you deal with your work is very easy to do is very importmant.

Troubleshooting Of Fiber Media Converter

1, the Power light does not shine

Power failure encountered in the Power light does not shine, just direct replace the transceiver or the power supply box, but the socket replaced before test voltage is normal, so as not to cause damage once.

2, the optical path Link light does not shine

a) Check the fiber optic cable line is open circuit, the available loopback test method or with optical power meter and light source testing.

b) power meter check the fiber line loss is beyond the scope of equipment to receive different transceiver reception range should be confirmed according to the actual situation.

c) Check whether the optical interface docking with the flange correctly.

d) Check the fiber optic interface transceiver is correct, the test commonly used transceiver swap.

e) transmission length and distance match, especially over long distances must be selected can reach the distance of Fiber Media Converter.

f) both ends of the transceiver model match the model of the card more mixed interpolation may lead to unreasonable or other faults.

g) transceiver to connect the fiber mode matching, single-mode card to use single-mode fiber, multimode card use multimode fiber.

h) damage to the port transceiver light from the Tour de France tests, such as ring, the Link light is still not lit, then judge for the optical interface failures.

3, the circuit Link light does not shine

a) Check the network cable is open circuit or bad contact.

b) Check the connection type to match some of the fiber optic transceiver does not yet support adaptive, according to the type of connection to select a crossover cable or straight cable.

c) to inspect equipment, the transfer rate to match, if not adaptive, when both ends of the mandatory rate mismatch may cause transmission interruptions.

d) switches Optical port is disable.

e) The transceiver circuit port is damaged.

4, the network packet loss is a serious

a) fiber optic transceiver damage, lightning or high-voltage transient packet loss in general can determine the transceiver damage.

b) The transceiver's power port and the Network Device Interface, or both ends of the device interface duplex mode mismatch.

c) fiber optic connectivity issues, line attenuation reaches a critical state often this happens.

d) The cable quality issues.

5, send and receive lights are normal, but the network is disconnected

a) and the upper switch port does not match the check is not easy to find fault, from the physical layer.

b) The transceiver is damaged, or hanged.

c) cable production error, the wrong fiber jumper production also make electrical port link lights, but the link does not conduction.

d) The single fiber conduction, some transceiver just received optical signal optical port LINK light to light up, at which point there is no light signal is sent.

7, commonly used in transceiver test methods

a) the substitution method: When a spare transceiver, using the substitution method to forensics transceiver problem is the most direct and quick way.

b) stand-alone test method: put aside the external connection circuit, stand-alone transceiver test directly connected, such as able to ping the General Principles of judgment for the transceiver to normal, if not to ping you need to check the upper fault.

c) both ends of the test method: both ends of the transceiver connected computer if ping, ping General Clauses exclude transceiver failure, such as the ping fails you need to check the reasons for the connection from the transceiver, the optical path network cable.
