How to convert fiber optic cables to SC

You can convert fiber optic cables to SC connectors either by using SC adapters for existing connectors or by terminating the cable ends with SC connectors.

Using SC Adapters

If your existing fiber cables have different connectors (e.g., ST, LC, or FC), the simplest method is to use SC adapters. These adapters allow you to connect a non-SC cable to an SC-terminated port without cutting or re-terminating the cable. SC adapters are available in simplex or duplex configurations and maintain precise fiber core alignment to minimize signal loss, ensuring reliable transmission in telecommunications, data centers, and network installations . For example, an ST-to-SC adapter can join an ST cable to an SC port.

Re-terminating Cables with SC Connectors

For a more permanent solution, you can replace the existing connector with an SC connector:

  1. Prepare the fiber cable: Strip the outer jacket, buffer, and cladding to expose the bare fiber.
  2. Clean the fiber: Use lint-free wipes and isopropyl alcohol to remove dust and oils.
  3. Attach the SC connector: SC connectors use a 2.5 mm ferrule and a push-pull latch mechanism. Follow the manufacturer's instructions for epoxy or mechanical splice termination.
  4. Polish and test: Ensure the fiber endface is polished correctly (UPC or APC) and test for insertion loss and return loss to confirm proper alignment .

Choosing the Right Method

  • Adapters are ideal for temporary connections, testing, or when you want to maintain the original cable.
  • Re-termination is preferred for permanent installations, high-performance networks, or when upgrading legacy systems to SC-based infrastructure . By understanding the differences between ST, LC, FC, and SC connectors and using the appropriate adapters or termination techniques, you can ensure low signal loss, reliable connections, and compatibility with SC-based systems .
