(What are the common types of fiber optic connectors? The most widely used in communication equipment are ST-type, FC-type, SC-type, LC-type and MU-type fiber optic connectors. Their common attribute is that they have optical ports in contact with each other; LC-type and MU-type fiber optic connectors are currently emerging. The emergence of a new generation of small-form-factor SFF (small-form-factor) connectors has improved the fiber density. The use of multi-core optical fiber connectors is a solution to achieve higher density fiber output. Multi-core optical fiber connectors include MTRJ type, MPO type, MD type and MPX type, among which MPO, MD and MPX types are mainly used to connect ribbons. Optical fiber, also known as ribbon fiber connector, can realize up to 24 fibers from a single connector. A list of commonly used fiber optic connector types19 is as follows:)
