How to Terminate Fiber Optic Cable with SC Fast Connector?

Terminating fiber optic cables with SC fast connectors is a crucial skill for anyone involved in fiber optic installations, repairs, or maintenance. SC (Subscriber Connector) fast connectors are widely used in various applications due to their ease of use and reliable performance. In this guide, we will walk you through the step-by-step process of terminating a fiber optic cable with an SC fast connector.

Step 1: Gather the Necessary Tools and Materials

Before you begin the termination process, make sure you have all the required tools and materials ready:

• SC fast connector

• Fiber optic cable (single-mode or multi-mode, as per your requirement)

• Fiber cleaver

• Fiber stripping tool

• Fiber cleaning supplies (lint-free wipes and fiber cleaning solution)

• Epoxy or adhesive (depending on the type of SC fast connector being used)

• Polishing film (for polishing the connector)

• Polishing puck or fixture (for holding the connector during polishing)

• Fiber inspection microscope or visual fault locator (VFL)

• Safety glasses and gloves

  
  

Step 2: Prepare the Fiber Cable

1.Strip the outer jacket: Use the fiber stripping tool to remove the outer jacket of the fiber cable, exposing the individual fiber(s). Be careful not to nick or damage the fibers during this process.

2.Remove the buffer coating: Once the fiber(s) are exposed, use the fiber stripping tool again to remove the buffer coating, leaving the bare fiber(s) ready for termination. The length of the exposed fiber should match the length required by the SC fast connector.

3.Clean the fiber(s): Wipe the bare fiber(s) with a lint-free wipe and fiber cleaning solution to remove any dust, oil, or contaminants. Cleanliness is essential for ensuring a successful termination.

Step 3: Cleaving the Fiber

1.Place the fiber into the cleaver: Insert the prepared fiber into the cleaver, aligning it carefully to ensure a perpendicular cleave.

2.Score the fiber: Lower the cleaver blade to score the fiber's surface gently. Be cautious not to apply excessive force to prevent any cracks or chips on the fiber.

3.Complete the cleave: Apply a controlled force to complete the cleave. A clean and smooth cleave is critical for achieving low-loss connections.

Step 4: Installing the SC Fast Connector

1.Open the connector: If you are using a pre-polished SC fast connector, open the connector housing and carefully insert the cleaved fiber into the connector ferrule. Ensure the fiber is fully seated and protruding slightly from the ferrule's end.

2.Apply epoxy or adhesive (if required): If you are using an SC fast connector that requires epoxy or adhesive, apply a small amount to the connector ferrule before inserting the cleaved fiber. Follow the manufacturer's guidelines for the specific epoxy or adhesive being used.

3.Cure the epoxy (if applicable): If you used epoxy, follow the curing instructions to ensure a secure bond between the fiber and the connector.

Step 5: Polishing the Connector

1.Place the connector in the polishing fixture: If you are using a pre-polished connector, skip this step. Otherwise, secure the connector in the polishing puck or fixture, ensuring the connector end protrudes slightly from the fixture.

2.Polish the connector: Use the polishing film to polish the connector end in a figure-eight motion. Start with a coarse-grit film and gradually move to finer grits for a smooth and polished finish.

3.Inspect the connector: After polishing, inspect the connector end using a fiber inspection microscope or VFL. Check for any defects, scratches, or contamination. A clean and well-polished connector ensures optimal performance.

Terminating fiber optic cables with SC fast connectors requires attention to detail and proper handling of delicate fibers. By following the step-by-step guide provided in this article, you can achieve successful and reliable fiber terminations, enabling efficient data transmission and communication in fiber optic networks. Always remember to adhere to safety guidelines and manufacturer's instructions when working with fiber optic cables and connectors.
