Description
Fiber optic patch cord is jumper cables from the equipment to the fiber optic cabling links, also called fiber optic jumper, fiber patch cord, fiber optic patch leads, etc. With a thick protective layer, it is generally used for the connection between the optical transceiver and the terminal box, widely applications like fiber optic communication systems, fiber optic access networks, fiber optic data transmission and local area networks.
Patch Cord Features
- High repeatability and high return loss;
- High stability and good interchangeability;
- Low insertion loss and high reliability;
- Three types of fiber end faces: PC, UPC, APC;
- The entire series of optical fibers can be used: multi-mode (50/125, 62.5/125, OM3, OM4, OM5), single-mode (G.652, G.655, G.657, etc.);
- GR 326, IEC61300-2, ROHS, IEC61753-1, IEC61754 standard compliance.
