#Loopback plug used for software

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.
