Fiber Optic Loopback Cables
Fiber Optic Loopback Cables by Amphenol Now In-Stock at Cables on Demand in the most popular connector configurations for testing the capabilities of your Single Mode (9/125) and Multimode (50/125 & 62.5/125) optical networking equipment. Our fiber loopbacks feature extremely low loss characteristics for transparent test operation. Loopbacks simply take the fiber TX (Transmit) channel and loop it back (i.e. loopback) to the corresponding RX (Receive) channel on a given optical port.
