What is the fiber optic cable plug called

Fiber optic cables use specialized connectors such as SC, LC, ST, FC, and MTP to join optical fibers with minimal signal loss.Fiber optic connectors are mechanical devices designed to align and join optical fibers, allowing light to pass through efficiently while enabling easy connection and disconnection compared to permanent splicing . The most widely used types include: SC (Subscriber Connector): Square-shaped with a push-pull coupling, commonly used in FTTH deployments, data centers, and GPON networks where low return loss is critical . LC (Lucent Connector): A smaller 1.25mm ferrule connector with a latch mechanism, ideal for high-density applications in modern data centers, supporting duplex or simplex configurations . ST (Straight Tip): Features a bayonet-style twist-lock, often used in legacy systems, industrial, and military networks requiring robust mechanical connections . FC (Ferrule Connector): Threaded coupling for secure connections in high-vibration environments like factories, railways, or aviation systems . MTP/MPO (Multi-Fiber Push-On): High-density connectors that can terminate multiple fibers in a single interface, widely used in data centers and telecom backbones for fast deployment and scalability . All fiber connectors include a ferrule to precisely align the fiber cores, often with a spring-loaded mechanism to ensure the fiber faces are pressed together, minimizing signal loss and reflection . Connectors are available for single-mode and multimode fibers, with polishing types such as UPC (Ultra Physical Contact) or APC (Angled Physical Contact) to match performance requirements . Choosing the right connector depends on the application, fiber type, density requirements, and environmental conditions, ensuring compatibility with patch panels, transceivers, and network equipment .
