What is Fiber Optic Patch Cord?

Fiber optic patch cord is also called fiber optic jumper, fiber optic patch cable, fiber optic jumper cable, fiber optic jumper cord. It is consists of fiber optic cable that terminated with fiber connector on both ends. The fiber patch cords used to interconnect or cross-connect fiber networks within structured cabling systems.

From the exterior, we summarize it as below formula:

Fiber patch cord= Fiber optic connector + Optical cable + Fiber optic connector

Common fiber optic patch cords

The classification of optical fiber patch cable can be based on the fiber connector, transmission medium, fiber core number, application environment and so on.

Fiber Optic Patch Cord Type by Transmission Medium:

1. Single mode optical fiber jumper: the general jacket is yellow, the diameter of the core is 8~10μm, the connector and protective sleeve is blue, and the transmission distance is longer.

2.Multi-mode optical fiber patch cord: generally orange, some are light blue (OM3), grey in connector, and transmission distance is short.

Fiber Patch Cable Type by Connector :

According to the structure of the connector, it can be divided into :

FC,SC, ST, LC, MTRJ, MPO, MU fiber optic jumper, S MA,,FDDI, E2000, DIN4, D4 fiber optic patch cable and so on.

The combination of the connection heads can be the same(A-A) or the different(A-B), that is hybrid type. More common fiber jumpers are SC-SC, FC-FC, LC-LC, FC-ST, SC-LC, SC-ST and so on.

Optical Fiber Patch Cord Type By Polishing Way:

It is divided into APC, UPC and PC

The PC ferrule surface is flat, which is widely used in telecom operators. The return loss ≥45 dB

The UPC inserting end face is flat, and its joint cross-section is flat,  the return loss ≥50 dB

In radio and TV and early CATV, the APC model is applied. The APC inserting end is oblique, the angle range is 30 degrees, and the top has oblique 8°±1°. The return loss of APC≥65 dB

Fiber Optic Patch Cord Type By Using Environment:

Armored fiber optic jumper: A new optical fiber jumper has the advantage of no need to use protective sleeve, save space, make construction more convenient and ensure safety.

Waterproof fiber optic jumper: Generally used for outdoor laying, it has a strong PU jacket and armor structure. It can resist high temperature and is suitable for using in harsh environments.
