What is a common connector used in multi-mode optical fibers?

In the context of multi-mode optical fibers, the ST (Straight Tip) connector is widely recognized and frequently used. Its design features a bayonet-style coupling mechanism, which allows for a secure lock and easy mating and demating. The ST connector was one of the first standard connectors developed for optical fibers, making it very popular in early installations of multi-mode fibers.

While the MTP/MPO (Multi-Fiber Push On) connector, LC (Lucent Connector), and SC (Standard Connector) are also used in multi-mode applications, the ST connector remains notable for its historical significance and continued use in various networking scenarios, particularly in legacy systems and certain educational environments. Each of these connectors has its specific applications, but in terms of historical context and traditional usage, the ST connector is a common choice for multi-mode optical fibers.
