DIN47256 fiber optic connector
This is a from Germany developed connectors. This connector pins and coupling sleeve structure and the FC-the same end surface treatment using PC lapping methods. Compared with FC connectors, its complex structure, internal metal structure with controlled pressure spring, you can avoid injury by docking too much pressure-side surface. In addition, high mechanical precision of this connector, thus small insertion loss values.
MT-RJ started in the development of NTT MT connector, with the same RJ-45 LAN connector latch body, by installing a small casing on both sides of the Guide PIN at the optical fiber, optical transceiver for ease and connected to connector end face fibre for dual-core (interval 0.75mm) arranges design, next generation high density fiber optic connector is used primarily for data transmission.
LC-style connector is a famous Bell (Bell) the Institute of research and development, using easy to use modular jacks (RJ) made from the latch mechanism. Of the PIN and sleeve size is half the normal size used by the SC, FC, etc, to 1.25mm. This can improve the fiber optic connector optical fiber distribution frame density. At present, in the area of single-mode SFF, LC type connector has actually occupy the dominant position, in multimode applications is growing rapidly.
MU (Miniature unit Coupling) connector to the current most used based on SC connectors, developed by NTT developed the world's smallest single-core optical fiber connectors. The casing of the connector using 1.25mm diameter and self-holding institutions, their advantage is able to achieve high density installations. Use of MU l.25mm diameter of casing, NTT MU connectors have been developed. They are used for fiber optic cable connection socket type connectors (MU-A series); self-holding institutions Backplane Connector (MU-B series), as well as simplified Sockets for connection LD/PD module with plug (MU-SR series). With the fiber network to rapid developments in the direction of greater bandwidth, greater capacity and widespread application of DWDM technology, demand for MU connectors will also quickly
