Mining optical cable category
1, according to the transmission medium in the cable - optical fiber (glass or plastic fiber) characteristics are divided into: single-mode fiber and multi-mode fiber,
2, according to the selection of optical fiber characteristics and mining optical fiber is divided into: single-mode optical fiber and multi-mode optical fiber
3, single mode (B): in the medium (generally silica, that is, glass) transmission only one wavelength (frequency), slightly thicker than the conductor (commonly known as glass wire) brittle, easy to break, tough (tension), with hair on the mechanical properties of almost the opposite, according to the characteristics of other components of the medium so that the optical transmission performance of the inconsistency, Single-mode fiber is subdivided into B1.1(non-dispersion-shifted single-mode fiber ITU-T G652) and B4(non-zero dispersion-shifted single-mode fiber ITU-T G655). Generally, the wavelength can be used is 1310nm or 1550nm, and the main single-mode fiber used is B1.1. Sometimes B for short means B1.1(non-canonical call)
4. Multi-mode A1(ITU-T G651): It means that multiple wavelengths (frequencies) can be transmitted simultaneously in the medium (through single mode). A conductor slightly thicker than a human hair (commonly known as the same as above) multi-mode fiber is subdivided into :A1a(50/125) and A1b(62.5/125) and collectively known as ITU-T G651. Generally, the wavelength used is 1310nm or 850nm
5, about the optical fiber transmission distance
Generally, it can reach 120km without relay in single-mode transmission and 2km in multi-mode transmission. The optical signal of 10/100/1000M can reach 60-80km in single mode transmission without relay. Multimode thing 500m--50/125um; 200m--62.5/125um, so the multi-mode is generally used for indoor or jumper, and the single mode is used for long-distance transmission in the field.
