Optical fiber connector of classification(1)
Date:2016.04.15 Source:opneti Hits:

  The optical fiber connector according to different transmission media can be divided into common silicon-based single-mode and multimode optical fiber connectors, as well as other issues such as the transmission medium in plastic optical fiber connector; press connection type head structure can be divided into: FC , SC, ST, LC, D4, DIN, MU, MT, and so various forms. Here are some current common fiber optic connectors:

FC-type optical fiber connector

  This connector was first developed by Japan's NTT. Ferrule Connector FC is the abbreviation, indicating that it is a way to strengthen the external metal sleeve, fastening means for the turnbuckle. The earliest, FC type connector, ceramic pins butt end face is used in flat-contact (FC). Such connections simple structure, easy to operate, easy to manufacture, but the fiber end face dust are more sensitive and prone to Fresnel reflection and improve return loss performance more difficult. Later, this type of connector has been improved, using the butt end faces spherical pin (PC), while the external structure has not changed, such that the insertion loss and return loss performance has been improved greatly.

SC fiber connector


  This is a company developed   by the Japanese NTT fiber-optic connectors. Its rectangular shell, size structure employed pin and coupling sleeve and FC type identical. Wherein the end face of the pins to use more PC or APC Polishing manner; fastening means it is a plug pin latch type, without rotation. Such low-cost connector, plug easy operation, small insertion loss fluctuation, high compressive strength, high mounting density.

  ST and SC connectors are two types of fiber optic connectors for 10Base-F connector, the connector is usually ST type, for 100Base-FX is, in most cases for the SC type connector. ST connector core exposed, SC connector cores inside the joint.
