How to Terminate Fiber Optic Cables with Epoxy

When you have bulk fiber optic cables on hand and need to terminate it with the fiber optic connectors, there are several options for you to handle this job: Epoxy and polish, mechanical cleave and crimp, and the chemical permanent method, fusing splicing the pigtails. The aim of terminating the fiber optic cables is to provide protections for the stripped fiber end in the connector. Poor termination job will result in large optical loss, even cause damages to the connectors and adapters. Among all the method mentioned above, epoxy and polishing is the cheap, fast and easy and low optical loss, so it is welcomed by most cable installers. Follow the steps and see how to terminate your fiber optic cables with the Epoxy.

First, prepare you cable by stripping the cable down to the bare fibers with a fiber stripper which you can get from FiberStore. After that, mix the epoxy resin and hardener that you have prepared ahead, and load them into a syrine( Ignore this step,if you are using a pre-loaded epoxy syringes). Now, it’s time to injuct the expoxy directly from the syringe into the connector ferrule.

Once you have prepared your connector with the epox, you re read to insert the fiber cable so that the cable is seated inside of the connector wall and the bare fiber core sticks out about a half an inch from the front of the ferrule. If your cable is jacked, you will need to use the cable crimping tool to protect the connector to the jacket and strength members of the cables. Two crimps would be necessary to finish the job properly.

The next step is curing the epoxy in the connectors. You may need to place the connected end into a curing holder first to make sure that the end of fiber will not get damaged in the process of curing. Then place the cable and curing holder into a curing oven, situate the connector to make the end is facing down, by doing which, it will ensure the epoxy does not come out of the back side of the connector and compromise the strength…
