Fiber Optic Patch Cord
Fiber Optic Patch Cord :
Fiber optic patch cord refers to the optical fiber that can be connected to desktop computer or device directly, convenient for device’s connectivity and management. The patch cord is used from device to fiber optic cabling link . It has thick layer of protection ,and is always uses in the connection between the optical and the terminal box.
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 transceiv
3. Must be use the protective cover out the connector, to avoid damage that dust and oil would make to the optical fiber coupling er 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.
