Terminating a fiber optic cable involves the process of connecting the cable to a connector or a device so that it can transmit data effectively. Here are the basic steps for terminating a fiber optic cable:
Materials and Tools You’ll Need: fiber optic technology
1.Fiber optic cable
2.Fiber optic connectors (typically SC, LC, ST, or MTP/MPO)
3.Fiber cleaver
4.Fiber optic termination kit
5.Fiber optic polishing films or fixtures
6.Epoxy or adhesive (depending on the connector type)
7.Fiber stripper
8.Fiber cleaning supplies (alcohol, lint-free wipes)
9.Heat shrink tubing (if using heat shrink connectors)
10.Heat gun (if using heat shrink connectors)
11.Fusion splicer (if splicing the fiber)
12.Fiber optic polishing machine (for polished connectors)
13.Fiber optic testing equipment (e.g., power meter and light source)
Termination Steps:
1.Prepare the Cable:
Measure and cut the fiber optic cable to the desired length.
Use a fiber stripper to remove the protective outer jacket and any strength members or additional layers of coating to expose the optical fibers.
2.Cleave the Fiber:
Use a fiber cleaver to make a clean, perpendicular cut on the fiber.
The cleave should be as flat and smooth as possible to ensure a good connection.
3.Prepare the Connector:
If using epoxy connectors, apply a small amount of epoxy to the connector’s ferrule.
If using adhesive connectors, the adhesive is pre-loaded.
If using heat shrink connectors, slide the heat shrink tubing onto the fiber.
4.Insert Fiber into Connector:
Carefully insert the cleaved end of the optical fiber into the connector.
Ensure that the fiber’s core aligns with the center of the connector’s ferrule.
5.Cure Epoxy (If Applicable):
If using epoxy connectors, the epoxy may need to be cured following the manufacturer’s instructions, usually involving a specific curing time and temperature.
6.Polish the Connector (If Necessary):
For some connectors, especially in high-performance applications, polishing may be required to achieve a low optical loss. This is typically done with special polishing films and fixtures.
7.Heat Shrink (If Applicable):
If using heat shrink connectors, use a heat gun to shrink the tubing, securing the fiber in place.
8.Clean the Connector:
Use lint-free wipes and isopropyl alcohol to clean the connector’s end face.
9.Test the Connection:
Connect the terminated cable to a test device or network.
Use fiber optic testing equipment (power meter and light source) to verify the quality of the connection and measure optical loss.
10.Protect the Termination:
If necessary, protect the terminated end with a dust cap.
Keep in mind that terminating fiber optic cables can be a delicate and precise process, and the specific steps and connector types may vary depending on the application and the equipment you are using. It’s essential to follow the manufacturer’s instructions and, if possible, have someone with experience in fiber optic termination guide you through the process, especially if you’re new to it.
