How to use a mechanical optical fiber splice for single mode and multimode fibers?

This ULTRAsplice is a high performance, easy to install reusable mechanical splice. It accepts fiber buffer sizes from 250-900µm.

The typical splice loss is less than 0.2 dB and return loss is less than -50 dB with a fiber retention of over 2 lbs.

Cleave, insert the fibers and secure by twisting a locking nut. Meets and exceeds Telcordia specifications.

You only need a fiber stripper, fiber cleaver, and an optional visual fault locator. No special tools are need.

Would you ever use this for permanent splice?
