Which connector is most commonly used for multimode fiber?

The most commonly used connector for multimode fiber is the SC connector. This choice is prevalent due to its design and performance characteristics that align well with multimode fiber applications.

The SC connector features a push-pull design, which allows for easy installation and removal, making it user-friendly in environments such as data centers and telecommunication networks where frequent connection changes may occur. Additionally, the SC connector can handle a greater number of simultaneous connections, contributing to its widespread adoption in multimode applications.

In multimode fiber installations, it's essential to use connectors that can minimize signal loss and maintain performance over distances typical for multimode setups. The SC connector has a good reputation for meeting these needs due to its robust build and effective transmission capabilities alongside multimode fibers.

While other connectors such as LC and ST are also used with multimode fiber, the SC connector's combination of usability and efficiency has made it the standard choice in many installations.
