Most connectors have epoxy resins or other adhesives to keep the fiber inside the splint of the connector and a fine polishing of the fiber end for a smooth finish. Follow the termination procedures carefully, as they have been developed to generate the lowest losses and the most reliable terminations. Use only the specified adhesives, since fiber bonding to the splint is vital to achieving lower losses and long-term performance.
We have seen people using epoxy adhesives from hardware stores, cyanoacrylate, among others, but then they repented. Only those adhesives approved by the manufacturers or distributors of the connectors can be used. If the adhesive does not work, something that is not so unusual when the splints of the connectors are made of metal, the fiber "pistons"
(protruding from the splint or retracting), which causes high losses and possible damage to the
coupled connector.
The polishing process takes three steps but only takes a minute: "polish in the air" to wear out the
protruding fiber, polish the fiber by holding it perpendicular to the polishing surface, on a soft pad
with a polishing disc, and Then perform a smooth final polish.

Epoxy / Polished
Most of the connectors and almost all industrial manufacturing terminations are the simple "epoxy /
polished" type, in which the fiber is glued to the epoxy connector and the end is polished with special granulated sandpaper. This method is the one that provides the most reliable connection,
lower losses (less than 0.5 dB) and lower costs, especially if many connectors are installed. The small the drop of hardened epoxy surrounding the fiber at the end of the splint makes the Cutting and polishing processes are much easier, it is virtually infallible. You can let the epoxy dry overnight or you can use an economical healing oven. A “heat gun” should never be used to try to cure the epoxy faster since uneven heat may not cure it completely or it may overheat, which will never cure. Also do not use " Hot Melt " ovens, as they have a much higher temperature and will ruin the epoxy.
Polishing/adhesive " Hot Melt " (hot melt)
This is the 3M brand name for a connector that already comes with the epoxy inside the connector
(actually, the dry glue). You must put the connector in a special oven. In a few minutes, the glue melts, then take out the connector, insert the bare fiber, let it cool and you are ready to polish. It is fast and easy, it has little loss, but it is not as economical as the epoxy type, which has become the favorite of many contractors who install relatively small amounts of connectors. Remember that you will have to use a special oven " Hot Melt ", since it needs a much higher temperature than what is used to cure the epoxy.
