Buying Fiber Optic Transceiver Modules

Finding a trusted retailer,fiber optic transceiver modules and fully knowing will be helpful when your purchase. You will have networking questions and concerns, so finding an experienced fiber networking supplier is very important. and you will need to know all the information to make the right choice when choosing manufacturers and their modules.

Fine optical fibers transport waves of data sent by fiber optical transceiver modules. Modules transport and receive optical signals. Under the Multi-Source Agreement these form factors are built by companies. Specific standards must be met in their building. Transfer speeds are what are used to classify optical transceivers together. Each supports rates from 1 Gbps to 10Gbps. Module factors known as SFP and GBIC are 1Gbps. These form factors support transmissions bigger than 4Gbps down to 100mbps. Modules known as XENPAK, XFP, X2 and SFP+ support speeds of up to 10 Gbps transportation.

SFP modules can be connected to small form factor. The modules are considered the updated version of the GBIC. GBIC is a half size larger, while SFP fiber interfaces to use a minimum. Achieving transport can range from 500 meters to 120 km +. They are easy to change and easy to work.

XENPAK Modules are the largest in the 10G transceiver interfaces and includes a dual fiber SC interface. Cisco SFP modules are available in multi-mode and single mode fiber optic cable and copper wire to operate. 15 meters is the length of a normal transmission module copper. 300 meters is the transmission range of multi-lines.


XFP transceivers are designed for network applications, 10G, 10G Ethernet included. The standard for development of these was created by some of the leading manufacturers in the field. Basic care and change, also hot pluggable small. This module is used in combination with multimode fiber.

GBIC stands for giga-bit interface converter. This works the transformation of optical information in a form for the Ethernet network to a form of fiber optic network. This module is added to the networks to fiber optic patch cords. GBIC rating is determined on its wavelength, bit rate optical power, and range. It is hot pluggable, which allows a port to be changed to another without having to shut down the switch or router.

Optical networking solutions is an industry that keeps growing and growing. The above list is just some of the optical options you must choose. Once again, finding the right distributor will be as important as the education of optical transceivers, and how they work. A supplier who sales a broad range of optical interfaces will be helpful.

The 100G Modules: Falling Prices But The Scale Rising

JDSU, has been among the industry leader in optical communications companies. In 2001, this company has created the myth of the field of optical communications $ 1,200 per share, of course, thanks to the Internet bubble economy, which to some extent, to wait until the Internet bubble burst, JDSU was even difficult to survive. However, after the ups and downs, JDSU ashes.
Up to now, JDSU worldwide with 4915 employees, a total of over 80 sales outlets, covering 164 countries. Its 2011 turnover reached 11.4 billion yuan, the largest S & P 500 (S & P 500) index members. Today, we learned that JDSU may be optical security logo of the money, perhaps industrial-grade lasers, perhaps because of the somatosensory game, of course, the most because Hewei name of JDSU in the field of optical communications and communications test.
With the outbreak of the broadband market, JDSU started to increase attention to the Chinese market.
Alan Lowe, president of JDSU's Communications and Commercial Optical Products Division, JDSU on the first quarter, 28 percent of the proceeds from the Asia-Pacific region, especially China business over the previous fiscal year to achieve substantial growth. In recent years to increase investment in China. Create a new broadband network R & D center in Shenzhen in 2011 JDSU to promote the innovation of next-generation broadband network agreement; set up a joint laboratory in Beijing with the Beijing University of Posts and Telecommunications, set up a special scholarship to train the field of optical communications personnel. Alan said: "to expand cooperation and investment for the JDSU bring considerable benefits, JDSU's commitment will continue to focus on the Chinese market, to invest in advanced technology development, is committed to the cause of science and technology for the benefit of mankind."
The contrast in the domestic competitors, such as Finsar. Both close to the strength in the field of optical components, optical modules, JDSU can provide testing services, and this is the Finsar unmatched.
It is precisely because of these advantages, JDSU and domestic manufacturers of optical communications, especially the steady growth of Huawei's cooperation, JDSU employees in Shenzhen, Beijing and Suzhou, has reached more than 500 people.
At present, the hot industry concern 100G JDSU's strengths, Huawei and other leading 100G vendors in the procurement of JDSU optical module. 100G optical module production capacity, our efforts have been made to ensure the stable supply, but the overall demand is too strong. Visit to China will focus on the Shenzhen Branch Supervision and 100G optical module production, and look forward to further increase production. "Alan said March 2012, 100G module prices dropped by 5 percent, is expected in June than in March fell 2 percent to 4 percent each quarter showing the price decline, the scale of the rising trend. "

The Flexibility of Fiber Optics

When people talk about the Internet, the cable TV system or the telephone system it is very likely that you have cable, optical fiber can be heard. They are regarded as strands of optically pure thin glass that carry digital information over long distances.Typical SC fiber optic adapter are with plastic housing and single mode SC/UPC adapter is blue color, single mode SC/APC adapter is green color, multimode SC/UPC adapter is beige color Most media used in combination because of the availability of higher bandwidth, the fiber optic light source far more than many other forms of electrical signal carrier to be worn.
Fiber optic communication systems have certainly developed the telecommunications industry and because of its advantages over electrical transmission line, copper wire communications in core networks are replaced by optical fibers. As will be fiber optic long, thin strands of pure thin glass, which denotes in bundles as Fiber optic cable, which are for light to transmit signals over large distances are arranged such works.
A single optical fiber consists of a core that the thin glass center of the fiber where the light passes, fairing,The new MIPP is a termination Patch Panel that need to be connected to active equipment. the outer optical material around the core, the light back into the core and a buffer reflecting coating which has a plastic coating is that the fiber from damage and moisture.
Due to its smooth transition, optical fibers for signal transmission are far more recommended. Can carry calbles with a minimum number of optical fiber amplifiers that the amount of data transferred in many electrical lines. If fiber cables running side by side long distances, they experience cross-talk, unlike some types of electrical cables. Although fiber optics higher the value, it will save some money in the long run with less maintenance.
Fiber Optics is thin, so in contrast to electrical signals in copper wires, light signals from one fiber to those of other fibers in the same cable that could affect results in clear reception. The loss of the signal is also less than in fiber optics into electrical copper wires therefore lower power transmitter can be used instead of the electrical high-voltage transmitter.
Since their suitability for use in digital signals, fiber optics used in particular in the telecommunications aspects. Due to the flexibility of uses fiberglass is often seen in almost every industry.

Information of Fiber Optic Attenuation

How to choose an optical attenuator. First,you need to check your application. This attenuator where and how to use it for? You must consider the factors in the test lab, you need a different attenuation, in your experiment? Variable attenuator,In most cases you will end up needed to use a Fiber Optic Attenuator and then will be a good choice. You must also consider the type and mode of the fiber. You must also decide what you need, the end result.
We use the attenuator is the path of the attenuation of light along glass or plastic fiber optic cable. the cable is often the jacket, in order to protect the fragile material. The sheath is often Kevlar, to add strength, but the decay does not require sheath or aramid, because of the small molded housing. The molded housing is usually made of metal or plastic.
Fixed optical attenuator – the use of the case, you know, you need the dB value of attenuation.
For example, you may need to reduce by 5dB of optical signals, so you will get a 5db attenuation. You should see your connection, so you can order the correct type of fiber optic attenuator. on the site, if you choose to select your attenuation certainly, and select the appropriate connector type site should contain the type of information on the connector and the decibel value. The connector type is very typical of the legislative Council LC/APC, SC/UPC, SC/APC/UPC bar code, Mu, FCs, FC/APC abd ST.
Like some websites britecom.net- just Google, he GE in-line Coupler easily adds a telephone at a different location without installing a new jack. Great for connecting 2 line cords to create a longer cord they say, good quality and reasonable price. They also said that good customer service. All you have to decide what is the best place to find your fiber optical attenuator, of course, is your choice. We have a free and great to know.

ADSL Tester

ADSL Tester stands for Asymmetric Digital Subscriber Line, which is a form of high-speed Internet access using standard phone lines. Unlike the standard modem, which can only provide download speeds of up to 56 kbps, ADSL can provide you with download speeds of up to eight mbps.
The download speed ADSL provides is variable, depending on your distance to the central office or to a remote router. The maximum download speed of eight mbps is only possible if you live within one mile of the office. The typical ADSL subscriber can expect download speeds of up to four mbps.
The main disadvantage of the ADSL is the fact that its high speed is only one-way. The upload speed of this Internet service is very slow, nearly comparable to a dial-up connection. This is why ADSL is heavily marketed to passive internet users, those that do not upload files on a regular basis. The typical Internet user only uses the Internet to download information. Therefore, high speed for one direction is generally adequate for them.
ADSL Line Tester Information
When using ADSL, your connection speed will vary with your distance to the central office. You will need a way to test the speed of your line. This is what an ADSL line tester is for. It will calculate your distance from the central office, or router, and determine the data rates possible. Having a line tester will assist your service provider in accelerating the installation of your service.
Different testers will give you different functions. A basic line tester can ping your line. It will send out a signal and measure the time it takes for it to reach its destination and come back to you. More advanced line testers can do more than simply ping your line. Some can also test all the functions of your DSL modem, as well as check the physical layers of the connection.

What is a Punch Down Tool?

Most copper networks are built using twisted-pair cable. Twist-pair cables are terminated in jacks, cross-connect blocks (66 blocks), or patch panels (110 blocks). The termination is done with a tool known as punch down tool.
The termination connects the twisted-pair cable conductor with insulation-displacement connectors (IDC). IDC is a little knife blade with a V-shaped gap or slit between them.
The punch down tool punches down and forces the twisted-pair cable conductor into the V. Then the IDC connector makes contact by cutting through, or displacing, the insulation around a single conductor inside a twisted-pair cable.
The punch down tool pushes a conductor between the sides of a "V" inside an IDC, allowing the small metal "knife" inside the connector to make contact with the inner conductor inside the wire.
A punch-down tool is really just a handle with a special blade that fits a particular IDC.
There are two main types of punch down tools (corresponding to two types of IDC terminations): the 66-block and the 110-block.
The 66-block is mostly used in cross-connect blocks for voice cross-connects. The 110-block is now generic in usage and is a newer design by AT&T. 110-Block is most used for data network, although it is not absolutely so.
The process of punching down a wire properly takes a considerable amount of force. You could just use a small flat-blade screwdriver, but you would probably break the wire or not be able to make the proper connection at all.
The punchdown tool helps you in applying the right amount of force in the right direction. Different blades are used depending on whether you are terminating 110-blocks or 66-blocks. Though the blades for each type are pretty different, most punch down tools on the market today can accept both types.
As you punch in with the tool, you load up a spring that then releases the proper amount of force to press the wire firmly into the connector while stripping the insulation off the side of the wire to assure a firm connection.

What is a LC Fiber Optical Attenuator?

LC optic fiber attenuator is a passive device used to reduce light signal intensity without significantly changing the waveform itself. This is often a requirement in Dense Wave Division Multiplexing (DWDM) and Erbium Doped Fiber Amplifier (EDFA) applications where the receiver cannot accept the signal generated from a high-power light source.
LC fiber optic attenuators are key in controlling controlling the power level of an optical path in fiber optic telecommunication systems. LC Build-on fiber optic attenuators are used to reduce excess optical power from the transmitter that can result in over-saturation of the receiver.
LC fiber optical attenuator features a type of metal-ion doped fiber which reduces the light signal as it passes through. This method of attenuation allows for higher performance than fiber splices or fiber offsets or fiber clearance, which function by misdirecting rather than absorbing the light signal.
Build-on type LC fiber optic attenuators are designed to provide flat spectral attenuation across the full spectrum range from 1280nm to 1624nm. This way the LC attenuators expand the capacity of optical networks by enabling the use of the E-band (1400-nm window) for optical transmission.
These attenuators feature simple and rugged structure utilizing ion doped fiber as the attenuating material. They can be placed directly on the active equipment and are capable of withstanding over 1W of high power light exposure for extended periods of time, making them well-suited to EDFA and other high-power applications.
Build-on style LC attenuators are a combination of a connector on one end, and an adapter on the other. This allows it to be "plugged-in" to almost any LC adapter. The assembly contains a ferrule that is available in standard polish connectors (PC) and 8 degree angle polish (APC). They are backward compatible with existing transmission equipment, while the APC attenuators provide superior reflection required for high power and analog equipment.

How to Choose Fiber Optic Power Meters

What is a fiber optic power meter? The fiber optic power meter measures how much light is coming out of a fiber optic cable. It can be used to determine the amount of light being generated by an optical source, or the amount of light being coupled into an optical receiver.
Optical power is usually measured in dBm, or decibels referenced to 1mW. These devices measure the average optical power, not the peak power, so they are sensitive to the duty cycle of the data transmitted.
Their wavelength and power range have to be appropriately matched to the system being measured. Most power meters used to test communication networks are designed to work at 850nm, 1300nm and 1500nm wavelength ranges and in the power range of -15 to -35dBm for multimode links, or 0-40dBm for single mode links.
What types of power meters are available?
Fiber optic power meters, like DMMs, come in a variety of types. The measurement uncertainty of practically all fiber optic power meters is the same, limited by the physical constrains of transferring standards with optical connections.
Most meters have an uncertainty of +/- 5% or approximately 0.2dB, no matter what the resolution of the display may be. Lower cost meters or those for field use usually have a resolution of 0.1dB, laboratory meters display 0.01dB, and a resolution of 0.001dB is available on a few specialized meters.
The appropriate resolution for a measurement should be chosen according to the test. Laboratory measurements of low-loss patch cables, connectors and splices can be made to 0.01dB resolution and an uncertainty of 0.05dB or less if great care is used in controlling the test conditions.
