Which connector is most commonly used for multimode fiber optic cables?

The most commonly used connector for multimode fiber optic cables is the SC (Subscriber Connector). This connector is favored in many installations due to its robust design and user-friendly push-pull mechanism, which eases the process of connecting and disconnecting cables. The SC connector is particularly well-suited for high-density applications, as its rectangular shape allows for close spacing in patch panels and other environments where space is limited. Additionally, the use of an industry-standard design makes it a popular choice across various networking and telecommunications applications.

While LC connectors are gaining popularity, especially in high-density environments, SC remains prevalent in many existing multimode fiber installations. MTP connectors serve a different purpose, mainly for high-bandwidth and multi-fiber applications, which are typically more specialized. Similarly, ST connectors, while historically significant, have seen a decline in usage due to the growing preference for connectors that offer improved performance and ease of use.
