Which type of connector is commonly used for fiber optic cables?

The commonly used connector for fiber optic cables is the SC connector. This connector is designed specifically for high-performance telecommunication and data applications that require fast, reliable connections. The SC connector features a push-pull design, which allows for easy insertion and removal, making it user-friendly in both installation and maintenance processes.

SC connectors are known for their low loss and high durability, which makes them particularly suitable for various fiber optic applications, including those found in premises cabling systems. They provide a stable connection and are widely adopted in both single-mode and multimode fiber applications.

While other connector types like RJ45, USB, and BNC have their specific uses—primarily in copper cabling or other data transmission scenarios—they are not suitable for fiber optic cables. RJ45 connectors are typically used for Ethernet connections, USB connectors are used for data and power transfer primarily in devices, and BNC connectors are utilized in coaxial cables for video signals. Thus, SC connectors are the correct choice when it comes to fiber optic cabling.
