Detailed Display of SM Fiber Patch Cord
This fiber cable is yellow, providing good protection for the internal fiber and ensuring durability. Length in 3 meters, it is suitable for various deployment scenarios in optical communication systems, such as connecting network devices, optical transceivers, and fiber optic distribution frames.
The goods comes in a transparent plastic bag, keeping the patch cord clean and protected during storage and transportation.

The one end is an SC connector (blue, with a push-pull latching mechanism) and the other end is an FC connector (with a metal ferrule and screw-on latching mechanism, featuring a white boot).
