Classification of optitap fiber connectors
The optitap fiber connector can be divided into common silicon-based optical fiber single-mode and multi-mode connectors according to different transmission media, and other optical fiber connectors such as plastic as the transmission medium; according to the structure of the connector, it can be divided into: FC , SC, ST, LC, D4, DIN, MU, MT and other forms. The optitap fiber connectors are used in a wide variety of applications. In the actual application process, we generally distinguish according to the structure of optitap fiber connector. The following are some common optitap fiber connectors:
FC type optitap fiber connector
FC is the abbreviation of Ferrule Connector, indicating that its external reinforcement method is a metal sleeve, and the fastening method is a turnbuckle. The earliest, FC type optitap fiber connector, the butt end face of the ceramic pin used is the plane contact method (FC). This type of connector is simple in structure, convenient in operation and easy to manufacture, but the fiber end is more sensitive to dust, and is prone to Fresnel reflection, making it difficult to improve return loss performance.
SC type optitap fiber connector
The SC type optitap fiber connector has a rectangular housing, and the dimensions of the pins and coupling sleeves used are exactly the same as those of the FC type. Among them, the end face of the pin mostly adopts PC or APC grinding method; the fastening method adopts the plug-in latch type, which does not need to be rotated. This type of connector is inexpensive, easy to plug and unplug, small fluctuation in insertion loss, high compressive strength, and high installation density.
MT-RJ type SC type optitap fiber connector
The MT-RJ type SC type optitap fiber connector has the same latching mechanism as the RJ-45 type LAN electrical connector. The optical fibers are aligned with the guide pins installed on both sides of the small sleeve. In order to facilitate connection with the optical transceiver, The connector end-face optical fiber is a double-core (0.75mm interval) arrangement design, which is the next-generation high-density optical fiber connector mainly used for data transmission.
LC type optitap fiber connector
The LC-style optitap fiber connector is constructed with an easy-to-operate modular jack (RJ) latch mechanism. The size of the pins and sleeves used is half the size of ordinary SC, FC, etc., which is 1.25mm. This can increase the density of fiber optic connectors in the fiber optic distribution frame. Currently, in single-mode SFF, LC-type connectors have actually dominated, and the application in multi-mode is also growing rapidly.
MU type optitap fiber connector
The MU optitap fiber connector is the world's smallest single-core fiber connector developed by NTT, based on the SC-type connector that is currently most used. The connector uses a 1.25mm diameter sleeve and a self-retaining mechanism, which has the advantage of enabling high-density mounting.
MC optitap fiber connector
The MC optitap fiber connector has a high density, up to twice that of the LC connector in the same space, making it the smallest and densest connector in the world.
