Optical fiber is divided into two main categories:
Single-mode Fiber (Single mode Fiber) : general optical Fiber jumper with yellow, joints and cases in blue; Transmission distance is longer than the other.
Multimode Fiber (Multi - mode Fiber) : general Fiber optic jumper with orange said, also some said with gray, joints and protection to beige or black; Transmission distance is short.
Purpose: single-mode transmission way longer than multimode
Only a pattern signal transmission optical fiber is a single-mode fiber, transmit signals of different models, optical fiber is a multimode fiber. In addition can distinguish by wavelength
1. The single mode fiber core diameter small (about 10 m m), only allow a mode transmission, dispersion, work in the long wavelength (1310 nm and 1550 nm), coupling with optical device is relatively difficult
Coupled with optical device is relatively easy
