SC Fiber Optic Connector

SC fiber optic connector is one of the most common connection devices in single-mode network equipment, and it is often found on optical transceivers. For 100Base-FX, the connectors are mostly SC type. It uses a 2.5 mm ferrule, which is different from ST/FC. It is a plug-in device that does not need to be rotated, that is, a snap-in square interface. The core of the SC connector is inside the connector.
SC is the abbreviation of Square Connector. Its shape is rectangular. This type of connector is affordable, easy to plug and unplug, has small fluctuations in insertion loss, high compressive strength, and high installation density. With so many advantages, it is widely used.

SC Fiber Connectors

Connect with ease using SC Fiber Connectors – the go-to choice for joining two fiber optic cable runs. With a simple push-pull design, these connectors are widely preferred in FTTH (fiber to the home) applications for both datacom and telecom. They are also a must-have for GBIC modules, making them a versatile and reliable option for your connectivity needs.


  • Push-Pull Latching Mechanism: Easy to install with a secure lock for stability.
  • Low Insertion Loss: Maintains signal integrity over long distances, typically less than 0.5 dB.
  • Durable Design: Withstands frequent connection and disconnection.
  • Compatibility: Versatile choice, compatible with a wide range of equipment for various applications.


  • Telecommunication networks
  • Internet service providers
  • Cable television
  • Military communications
