Structure:

Fiber optic patch cord is similar to coaxial cable , but without mesh shield . Its center is core of glass for light propagation. The diameter of core is 15μm~50μm in multi-mode optical fiber ,equal to the thickness of human hair. But the diameter of single-mode optical fiber core is 8μm~10μm.

Classification:

According to different transmission media, fiber optic patch cord can be divided to common silicon-based optical fiber, Single-mode and Multi-mode patch cord, and other fiber optic patch cord that transport through media such as plastic.

According to connector structure, it can be divided to patch cord of FC, SC, ST, LC, MTRJ, MU, E2000, DIN4, etc.

Common fiber optic patch cord can also be classified to FC-FC,FC-SC,FC-LC,FC-ST,SC-SC,SC-ST, etc.   

Single-mode fiber:   Color is yellow. The connector and protective sleeve are blue. It can transport a long way.  

Multi-mode fiber:    Color is orange or grey . The connector and protective sleeve are beige or black. Its transmission distance is short.

Outer protection layer materials:

PVC, LSZH.

Features:

1. Low insertion loss
2. High return loss
3. Good repeatability
4. Good exchangeability
5. Excellent environmental adaptability

Application:

Telecommunication, FTTX+LAN, FTTH,  Video Transmission, Optical

Fiber Sensor, Testing equipment, CATV

Cautions:

1. Don’t bend and circle the fiber optic patch cord excessively, this will increase the attenuation of light during transmission.
2. The optical module transceiver wavelength of fiber optic patch cord must be consistent,       which means it should be the same wavelength of optical module at the two ends of it.
3. Must be use the protective cover out the connector, to avoid damage that dust and oil would make to the optical fiber coupling .
