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/

Some Of The Knowledge About Optical Fiber Adapter

Fiber Optic adapter (also known as the flange), also known as fiber optic connectors, optical fiber connectors connecting parts. The products include: FC SC ST LC MTRJ. Widely used in optical fiber distribution frame (ODF). 

Fiber optic communications equipment. Instruments. Superior performance, stable and reliable.

Fiber between its opening within the casing to connect the adapter to ensure maximum connectivity between the fiber jumpers. In a variety of panel, but also design a variety of fine fixed flange.
Transform adapter type can be connected to different types of fiber optic jumper interface, and provides a connection between the APC face double or more may even improve the installation degrees.

Fiber adapters Category: FC/PC FC/UPC FC/APC SC/PC SC/UPC SC/APC ST/PC ST/UPC SC/APC; Optical fiber adapter have SC, FC, the cent of ST.

SC representative Standard Connector; ST representative Straight Tip, FC representative Fiber Optic connector. 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.

"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.

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.
