Categorized by connectors, fiber optic loopback has SC, LC, MTRJ, E2000 and even MPO types, etc. We know that the fiber optic cables are having different connectors and in order to comply with this different loop back cables and adaptors are also available.
Similar to other cables, it also has multiple classifications of fiber types, connector types for different needs.
#Make a loopback cable Patch#
In a word, fiber optic loopback is basically a patch cord used for fiber optic loopback testing. You can have a look at this video also to get a better understanding of loop back testing. Fiber optic loopback testing is the easiest way to ensure that the transceiver works faultlessly. Then we can compare the transmitted pattern with the received pattern to troubleshoot a defective node in the network. Thus, during the testing process, the loopback cable directly routes the laser signal from the transmitter port back to the receiver port. When performing the loopback test, the fiber loopback cable can be directly plugged into the output and input port of transceiver module respectively (the ports at the ends of the connection must be compatible). The former one is to send out laser signals and the latter is to receive signals. As we all know, transceiver module has two ports, a transmitter port and a receiver port. So the common application of loopback cable is Loopback Test.įiber loopback cable is often utilized to check whether the transceiver module is working perfectly as designed. If the data sent out into the loopback plug is identical to the data received from the loopback plug, you can assume that the basic communication functions of the port are working properly.
#Make a loopback cable software#
The loopback cables are often used in conjunction with testing software to “loop” traffic right back into the port. Loopback cable connection in a SFP Module
Further to simply this, we can say that fiber optic loopback incorporates two fiber optic connectors which are plugged into the output and input port of the equipment respectively. And the looped space is reduced for an easier usage and economic package.īy using fiber optic loopback cable or fiber optic loopback module for data transmission, the signal emitted by the device is looped from the transmit (Tx) end of an active component back to the receive (Rx) end of the same component. As for fiber optic loopback module, the biggest difference is that it has a enclosure to protect the inside cable. When sticking the connectors together, the cable will shape like a loop. It is equipped with two fiber optic connectors on each end of the cable. Fiber optic loopback cable is the traditional fiber optic loopback with a visible cable. Loopback testing is generally achieved with the help of loop back cables or loop back module/adaptor. The deployment of fiber optic loopback components has greatly saved the trouble for device checking. By diagnosing the problems of optical network, fiber optic loopback provides an easy way to test the performance of the optical fiber cabling, SFP Modules, device port or the entire network devices itself.įiber Optic Loopback Cable or loopback module
It is very useful for solving physical connection problems. In terms of telecommunication, loopback is a hardware or software method to feed a received signal or data back to the sender. Fiber optic loopback is widely used for various applications. Generally, loopback is known as the routing of electronic signals, digital data streams, or flows of items back to their source without intentional processing or modification. Let us see more about what is fiber optic loopback cabling and its various methods. The loopback signal is used for diagnosing the networking problems. While you can see that almost all of these are using some kind of expensive equipments and skilled training is required loop back testing method is very cost effective and easy way for fiber optic troubleshooting. In the event of troubleshooting or implementation there are many tools used, such as visual faults locator, optical power meter, & OTDR and so on. So it’s very important that we need to make sure that this is working properly and maintained. We all know that the importance of fiber optic cabling and its role in all major applications.
