Optical fiber connector, also is access to the optical module optical fiber connector, also has many kinds, and are not to use each other. Not always contact fiber may be mistaken for GBIC and SFP module optical fiber connector is the same, but actually it is not. SFP module is connected to the LC fiber optic connector, and the GBIC connection is the SC fiber optic connector. On the network project of several commonly used optical fiber connector detail:
FC type optical fiber connector: external reinforcement is a metal sleeve, fastening means for turnbuckles. ODF in general ( side of the wiring frame using at most)
The SC type optical fiber connector: connect to the GBIC light module connector, its shell is a rectangular, fastening means is the use of plug pin latch type, do not need to be rotated. ( routers switches with most routers exchange router switching )
The ST type optical fiber connector: commonly used in optical fiber distribution frame, shell is a circular, fastening means for turnbuckles. ( for 10Base-F connection, the connector is typically ST type. Commonly used in the optical fiber distribution frame )
The LC: SFP type optical fiber connector connecting the module connector, it uses the convenient operation of the modular jack ( RJ ) latch mechanism. ( routing device use.)
The MT-RJ: transceiver square optical fiber connector, a dual fiber transceiver
A variety of optical interface type
Optical fiber connector
The FC round thread ( wiring rack for most )
ST clamping type round
SC clamping type square ( routers switches with most )
PC micro spherical grinding and polishing
APC is a 8 degree angle and micro spherical grinding and polishing
MT-RJ square, a dual fiber transceiver ( Huawei 8850. )
Fiber optic modules: general support hot plug
GBIC Giga Bitrate Interface Converter, using the optical interface for the SC or ST type
SFP small package GBIC, used for LC type optical fiber
The use of optical fiber:
Single mode: L, 1310 LH wavelength wavelength single mode of long distance 13101550
Multimode: 850 SM wavelength
SX / LH can be expressed using monomode or multimode optical fiber in said pigtail joint tagging, we often can see" FC / PC"," SC / PC", its meaning is as follows
" /" in front of a portion of said pigtail connector type
" SC" joint square connector is standard, made of engineering plastic, high temperature resistance, not easy to oxidize advantages. Transmission equipment side optical interface for general use SC joint
" LC" joint SC joint shape similarity, a smaller SC joint.
" FC" joint metal joints, generally in the ODF side of the joint, metal pluggable number more than plastic. Connector signal more varieties, in addition to the three, and MTRJ, ST, MU etc.,
" /" behind that optical fiber joint section process, namely the grinding method.
" PC" in telecom operators of the equipment in the application of the most extensive, the joint section is flat.
" UPC" is" PC" loss of small, generally used for the special needs of the equipment, some foreign manufacturers ODF frame skip fiber is used in FC / UPC, mainly to improve ODF device index.
