The Fiber Optic Loopback is a diagnostic tool used in fiber optic networks to test, troubleshoot, and verify the functionality of optical equipment and network connections. It works by redirecting an optical signal back into the same port from which it was transmitted, thereby completing the optical circuit. This loopback feature allows for the assessment of signal integrity, transmission paths, and overall system performance without the need for a full end-to-end connection.   Read More>
