FiberOpticx Xpress Fiber Connector - LC 50 micron - 6 Pack FiberOpticx Xpress Fiber Connector - LC 50 micron - 6 Pack

FiberOpticx Xpress Fiber Connector - LC 50 Micron - 6 Pack from Computer Cable Store™. SMP's Xpress Fiber Connectors are the new generation in field installable fiber terminations. These connectors eliminate the need for messy epoxies and expensive tools by offering a pre-polished solution that can be installed in minutes. Xpress Connectors have a prestubbed factory polished ferrule that joins to the fiber using a precise mechanical alignment and a special low loss index matching gel. Each Connector comes with a specially designed clip that holds the clamping devices open for the fiber to be inserted. Once the fiber is inserted, squeeze the clip to release the blades, remove clip and discard.
A micrometre or micron (American spelling: micrometer; symbol µm) is one millionth of a metre, or equivalently one thousandth of a millimetre. It is also commonly known as a micron. It can be written in scientific notation as 1×10-6 m, meaning 1/1 000 000 m.

Steps for terminating fiber optic cable using epoxy

Once you have your bulk fiber cable, follow the steps below:

To begin, strip the cable down to the bare fiber using an appropriate fiber stripper such as the FiberOpticx Fiber Stripper. After you have prepared the end of the cable you may begin to mix the epoxy resin and hardener together and load it into a syringe, unless of course you are using pre-loaded epoxy syringes, which are premixed and kept frozen until use. Now, from the syringe you must inject the epoxy directly into the connector ferrule.

Once you have your connector properly prepared with epoxy, you are ready 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. At this point, if your cable is jacketed, you will want to use a crimping tool such as the Premier Master Crimp Tool to secure the connector to the jacket and strength members of the cable. Two crimps may be required to accomplish this properly.

The next step in the process is allowing the epoxy to cure. Place the connected end into a curing holder to ensure that the end of the fiber is not damaged while curing. Now place the cable and curing holder into a curing oven. To avoid “wicking” while curing with a conventional oven, situate the connector so that the end is facing down. This positioning will ensure that the epoxy does not come out of the back side of the connector and compromise the strength member of the cable. Refer to the documentation of your specific epoxy for accurate curing times and temperatures.

Having sufficiently cured the epoxy you are now ready to move on to the next step, cleaving the excess protruding fiber core. You will want to cleave the fiber with a fiber cleaver tool such as the FiberOpticx Economy Fiber Cleaver, as close to the ferrule tip as possible while avoiding any sort of twisting motion. Once cleaved, it is important that you properly dispose of the fiber clipping. A regular piece of tape will do just fine at retaining your fiber debris. If you do not properly dispose of all fiber pieces they could easily end up in your skin or even in somebody’s eye or respiratory system. A short strand of fiber can cause more damage than you would at first imagine.

With the excess fiber cleaved and properly disposed of, you may begin the task of polishing the fiber end to a smooth finish. Using either fiber polishing film or a fiber polishing tool you will effectively remove any excess epoxy from the ferrule tip and buff out any imperfections on the face of the fiber. Without a smooth fiber surface any light passing through is subject to loss. The idea is to start with a coarse grit and work your way to a very fine grit film.

If you are satisfied with your polished finish then you may move on to the cleaning of the ferrule and fiber tip. With a lint-free wipe dipped in 99% reagent-grade alcohol, gently wipe the surface area of the ferrule and fiber tip and immediately wipe them dry with another dry lint-free wipe. You may optionally use a can of compressed air to finish the process.

Your connectorized cable is now complete. To ensure good standards, however, it is wise to inspect the tip with a 100x to 200x microscope such as the Fiber Inspection Microscrope. Finally, test your cable with an optical fiber testing tool for insertion loss and return loss where needed.
