12F MTP MPO Female SM Loopback

Optical fiber loopback is a medium used to provide a temporary return line for optical fiber signals. It can provide a rich and easy-to-manage optical fiber loop and effectively eliminate bending losses. It is often used in the field of optical fiber testing or network restoration to diagnose problems in optical network equipment. . Sending a loopback test to network devices one at a time is a technique that detects a certain problem individually.
