How to test the loopback mode of an optical module
Perform an external loopback test to check whether the optical module is normal. By looping the transmitted signal (Tx) directly back to the receiving end (Rx), it enables a closed test without requiring a live network connection. What is a loopback test? The loopback test is a common testing. When troubleshooting a suspect port or verifying new hardware, a fiber-optic loopback test gives you a fast, definitive answer on whether an interface is healthy. The methodology is simple: start at the physical layer and work your way up the stack, confirming each layer before moving to the next. For more background theory, please read on.
