各种光纤接口类型介绍（Introduction of various optical fiber interface types）

各种光纤接口类型介绍（Introduction of various optical fiber interface types） Various types of optical fiber interface introduction Optical fiber connector FC round thread (maximum frame use) ST clamped circular SC clamped square (most router switch used) PC microspheres surface grinding and polishing APC is a 8 degree angle and microspheres surface grinding and polishing MT-RJ square, a dual fiber transceiver (HUAWEI 8850 useful) Optical module: general support hot swappable, GBIC Giga Bitrate Interface Converter, the optical fiber interface used for SC or ST SFP small package GBIC, using optical fiber LC The use of optical fiber: Single mode: L, wavelength 1310 LH long single-mode wavelengthMultimode wavelength 850: SM SX/LH said you can use single mode or multimode fiber In the joint annotation? Said pigtail, we can often see the FC/PC, SC/PC, its meaning is as follows ? / the front part of said pigtail connector type SC is a joint standard type joint, used engineering plastics, high temperature, not easily oxidized advantages. The side light transmission equipment with the general SC interface connector LC joint and SC joint shape similar to smaller than SC joint. FC is a joint metal joint, commonly used on the ODF side, metal joint pluggable number more than plastic. More varieties? Signal connector, in addition to the three described above, as well as MTRJ, ST, MU, the appearance is shown below ? / behind the show that optical fiber joint sectional process, namely grinding way. PC in the telecom equipment is most widely used, the joint section is flat. UPC the loss is smaller than PC, generally used for the special needs of the equipment, some foreign manufacturers ODF frame internal jump fiber is used FC/UPC, mainly to improve their index of ODF equipment. In addition, widely used in radio and television? And early CATV in the APC model, the pigtail head adopts angle end, can improve the quality of TV signal, the main reason is that the TV signal is analog opti
