To finish the test, two technology are required. Required materials needed are a roll of tape and the electric torch. Each technician is stationed at each end of the fiber link, perhaps in two different telecom closets which is where the fibers are usually terminated. Each technician must identify the specific fiber’s connector end, which in most cases is connected to an adapter on the back plane of the Fibre Optic Patch Panel or termination box.the test include the fiber connector (called the ferrule) directly against the electric torch with the light on. it must unlink the fiber connector from the patch panel adapter so that the tip of the fiber can be directly applied to the electric torch’s lens. When unlink the connector and extracting it a short distance from the patch panel, with at least enough slack to reach the electric torch lens. There are two prevalent types of fiber connectors in use today. The ST or round connector disconnects by pushing the connector toward the adapter and turning the connector body counter clockwise ¼ turn and then pulling the connector away from the termination. The SC or square connector is a push-pull termination and can be removed by simply grasping the connector body and pulling it out. In no case should a technician use any hand tools such as pliers to remove the connectors; if you cannot get the connector free by using just your fingers you are not doing the disconnection correctly.

s we know, fiber optic connector is an important fiber optic component used to link two fiber optic lines together. Beside connector, there is also another item, which is fiber optic adapter with panels to connecting multi fiber optic line. Specifically, the fiber optic adapter is a small device that used to terminate or link the fiber optic cables or fiber optic connectors between two fiber optic lines. In order to realize the fluent fiber optic connection, the fiber optic adapter panel shapes or types should be in accordance with the fiber optic connectors or cables. Common shapes of the adapters are square, rectangular, or round that with FC, LC, ST, SC, MTRJ types. There are also single mode and multimode fiber optic adapters or single mode and multimode fiber optic connections. So when purchasing fiber optic adapters for fiber connections, it is essential to choose the right fiber optic adapter according to the fiber optic connector or fiber optic cables.
Standard or flange fiber optic adapter is a typical type used to connect the same types of optical connector, there are SC, ST, LC and MTRJ type available for choosing. These adapters are comprised of two or more female connections that fiber optic cables can be plugged into. flange fiber optic adapters are typically with ceramic sleeves, fitting for both single mode and multimode fiber optic connections.
Hybrid fiber optic adapters are another type used to link two different kinds of fiber connectors or cable assemblies. For example, LC to SC hybrid adapter, it can link LC connector at one side and SC connector at the other side. Hybrid fiber adapters can be also used for single mode and multimode fiber optic connections with PC or APC sleeves, in simplex and duplex style. Hybrid fiber adapters use high precision ceramic sleeves because it can provide reliable ferrule mating and ensure low insertion loss and return loss during the connecting. This type of optical fiber adapters is with compact sized and widely used for network environments integrating different configurations and telecommunications networks.
Bare fiber adapter is structured with optic fibers on one side and the adapter on the other side. It is used to link the bare optical fiber cable to fiber optic equipments. The adapter side is a connector that can plug into the equipment and enable a quick and easy termination for the optic fiber. Because this feature of the bare fiber adapters, they are widely used for emergency situation for fast and temporary fiber optic or urgent connection, testing bare fiber, fiber on the reel, fiber before and after installation and so on. SC, FC, LC, ST bare fiber adapters is now available in the market.
A single optical fiber adapter usually could hold a dozen of cables, if you splice multiple adapters together, it can even make hundreds or thousands of connection. Knowing what kind of connections, multimode or single mode, simplex or duplex, as well as the connector types can help you choose the corresponding right type of optical fiber adapter for application.

WHAT IS A FIBER LOOPBACK CABLE?

by http://www.fiber-mart.com

Fiber loopback is a media of return patch for a fiber optic signal that widely used for fiber optic testing, fiber network repair and fiber optic equipment diagnosis. Loopback test is a hardware or software method to test physical link problems of the fiber optic networks. It is realized by feeding a received signal or data back to the sender. Fiber optic loopback cables types is classified based on the fiber connector types, optic fiber modes.
Traditional fiber optic loopback is like a fiber optic patch cable with two fiber connectors at each end, forming a loop. Nowadays there are also another improved fiber loopbacks which called molded fiber optic loopbacks or fiber optic loopback modules. It is more compact sized and stronger. The molded loopback use an outer enclosure to protect it and from the outside you do not see the optical cables, they are more compacted size and stronger then the fiber loopback cables.
Just like the fiber patch cable, the fiber loopbacks is made up of different kinds of outer jackets, cable diameters, length or terminations that various according to customers’ special requirements.

40G LR4 QSFP+ Transceiver

Conforming to the 802.3ba (40GBASE-LR4) standard, the 40G LR4 QSFP+ transceiver together with the LC connector can support an optical link length up to 10 kilometers over single mode fiber. 40G LR4 QSFP+ transceivers offer 4 independent transmit and receive channels. And to realize the function of transmitting the 4-channel signals over the single mode fiber, this kind of transceiver has to introduce MUX/DEMUX to multiplex/de-multiplex optical signals.the working principle of this kind of QSFP+ transceiver is : In the transmit side, four 10 Gbp/s serial data streams are passed to laser drivers. The laser drivers control directly modulated lasers (DMLs) with wavelengths. the output of the four DMLs are optically multiplexed to a single-mode fiber through an industry-standard LC connector. In the receive side, the four 10 Gbp/s optical data streams are optically de-multiplexed by the integrated optical demultiplexer; then, each data steam is recovered by a PIN photodetector/transimpedance amplifier and passed to an output driver. The following figure shows the functional block diagram of the 40G LR4 QSFP+ transceiver.

40G SR4 QSFP+ Transceiver

40GBASE-SR4 QSFP+, Short-reach (SR) transceivers for 40G connectivity in a QSFP form factor, uses independent transmitter and receiver sections, each with 4 parallel fiber strands. It can transmit 150 meters over OM4 MMF. For a 40G connection, 8 fiber strands are required, and 12-fiber MPO connectors are used. Consequently, 4 fiber strands in each connection are wasted .For most data center networks, the aggregation-layer fiber infrastructure is built for 10G connectivity. That either supports direct connections between devices over LC-to-LC MMF, or uses LC-to-LC fibers to attach devices to patch panels. Regular duplex LC-to-LC fibers cannot be directly reused for 40G connectivity using traditional 40G transceivers.The operating principle of the 40G SR4 QSFP+ Transceiver is : the transmitter converts parallel electrical input signals into parallel optical signals through the use of a laser array. Then the parallel optical signals are transmitted parallelly through the multimode fiber ribbon. Reversely, the receiver converts parallel optical input signals via a photo detector array into parallel electrical output signals. The following figure shows the functional block diagram of the 40G SR4 QSFP+ Transceiver.

TIPS TO CLEAN FIBER OPTIC CONNECTORS

by http://www.fiber-mart.com

Fiber Optic Connectors are susceptible to be damaged which is not immediately obvious to the naked eye. The damage can have significant effects on measurements. Member any degradation of a fiber ferrule or fiber endface, any stray particles or finger oil on the endface, can have a significant effect on connector performance.
Fiber optic connector and connector ferrules have to be completely cleaned to make sure the trouble totally free working of fiber optic systems. As you’ve devote superior money installing a fiber optic, you might want to opt for a world course fiber optic connector cleaner and bnc coaxial connector to help keep it in superior shape.
Well, cleaning fiber optic connector can be done either with the help of a professional service provider or with the help of DIY kits. Below are a couple of time-tested methods.
1. Use Wipes And Solvents
This is probably the most widely used method of cleaning for the fiber optic parts. Cotton, cloth or lens paper is usually used for using this technique. Fabric and/or composite material wipes provide combined mechanical action and absorbency to remove contamination. Wipes should be used with a resilient pad in order avoid potential scratching of the connector end-face. Most solvents can provide good cleaning for the surfaces and tend to leave a slight residue that evaporates after a while.
This method is appropriate for cleaning connectors with exposed ferrules or termini but cannot be used to clean connector end-faces within alignment sleeves. The wipe should be constructed of material that is lint free and non-debris producing during the cleaning process. Please note that dry wipes have been shown to leave a static charge on the end-face of the connector which can thereafter attract particulate contamination. Therefore it is recommended that a static dissipative solvent be used with a dry wipe to eliminate this condition.
If the connector is not clean after the first cleaning, the process can be repeated perhaps with slightly more pressure on the connector to increase the mechanical action and perhaps making several stokes from the damp to dry sections of the cleaning material.
2. Cleaning Through Connector Reels
Optipop and Cletop are the most widely used reel connectors that are used in the industry for proper cleaning solutions. These work on the function of a resilient pad, sliding dust cover as well as a certain mechanism that tends to keep these small parts of the gadget working known as the ratcheting mechanism. The connector is inserted into an Fiber Optic Inspection scopes. This is done to check how clean the connector is.
About Solvents
Solvents used to clean fiber optics should be static-dissipative and residue-free. Many solvents are flammable and/or packaged so that transportation of the solvent is considered a hazardous material increasing cost of shipment and storage of the solvent. However, there are solvents available that are non-flammable and non-hazardous and packaged so that shipping requires no additional fees or paperwork.
Mind:
The methods require technical skill and expertize, it is advisable to trust the best in line professionals for fiber optic cleaning. Professional groups will not only ensure that your connectors are taken good care of, but also will prevent any sort of technical failures due to improper cleaning techniques.
