Single Mode Multimode ST Fiber Optic Connector Round Threaded

ST Single / Multimode Fiber Optic Connectors

Introduction of various fiber interface types
Fiber optic connector
FC round threaded (most used on patch panels)
ST snap-on round type
SC card-connected square type (most used on router switches)
PC Microsphere Grinding and Polishing
APC is at an angle of 8 degrees and is micro-spherical grinding and polishing
MT-RJ square type, one dual-fiber transceiver (useful on Huawei 8850)

Optical fiber module: generally supports hot swap
GBIC Giga Bitrate Interface Converter, the optical fiber interface used is mostly SC or ST type
SFP small package GBIC, the optical fiber used is LC type
Single mode: L, wavelength 1310, single mode long distance LH, wavelength 1310, 1550
Multimode: SM wavelength 850
SX/LH means that single-mode or multi-mode fiber can be used Forum.
In the label indicating the pigtail connector, we can often see "FC/PC", "SC/PC", etc. The meanings are as follows:
l The part in front of "/" indicates the connector type of the pigtail
The "SC" connector is a standard square connector, using engineering plastics, which has the advantages of high temperature resistance and not easy to oxidize. The optical interface of the transmission equipment side generally uses the SC connector
The "LC" connector is similar in shape to the SC connector, but smaller than the SC connector.
The "FC" connector is a metal connector, which is generally used on the ODF side. The metal connector can be plugged in more times than plastic.
