What is a fiber optic connector? What are the types of fiber optic connectors?

Fiber optic connector is a removable, movable, repeatedly plugged connection device that connects one optical fiber to another, also known as fiber optic movable connector. It can achieve a low-loss connection between optical fibers or between optical fibers and cables, effectively reducing the impact of fiber optic connections on the signal. Fiber optic connectors are mainly composed of four parts: pins, connector body, fiber optic cable and connection device. Fiber optic connectors need to meet many requirements in terms of characteristics, including fiber optic transceiver insertion loss is less than 0.5dB, return loss is greater than 25dB; fiber optic connector tensile strength is greater than 90N; fiber optic transceiver operating temperature range of -40 ° C ~ 70 ° C, the number of times more than 1,000 times insertion and extraction, and so on.

-I. What are the types of fiber optic connectors? According to the different transmission media, fiber optic connectors can be divided into single-mode fiber optic connectors and multi-mode fiber optic connectors; and according to the different connector structures, they can be divided into LC fiber optic connectors, SC fiber optic connectors, FC fiber optic connectors, ST fiber optic connectors, MPO/MTP fiber optic connectors, MT-RJ fiber optic connectors, MU fiber optic connectors, DIN fiber optic connectors, E2000 LC fiber optic connector is developed by Bell Research Laboratories, its pin and sleeve size of 1.25mm, is half of SC/FC fiber optic transceiver, using jack (RJ) latch fastening, generally used in high-density fiber optic patch panels.SC fiber optic connector is developed by NTT Japan, its shell is rectangular, the size of the pin 2.5mm, using plug pin latch fastening, generally used in high density fiber optic distribution frame. SC fiber optic connector is developed by NTT Japan, its shell is rectangular, the pin size is 2.5mm, the use of insertion and extraction pin latch fastening method, insertion method is simple and convenient.FC fiber optic connector is also developed by NTT Japan, the size of the pin is 2.5mm, however, FC fiber optic connector pin is relatively short, the surface of its use of the metal casing, the screw fastening method, the fiber optic connector is a greater feature of the installation of the connector is not easy to fall off.MPO/MTP fiber optic connector is a specialized for multi-fiber ribbon cable. A special multi-fiber ribbon cable for the manufacture of fiber optic connectors, with 4/6/8/12/24 cores and other fiber models, MPO/MTP fiber optic connectors have a small size, the number of cores and other characteristics, generally used in high-density fiber optic links.
