This mechanical splice is a high performance, low cost, easy to install, fully mechanical Fibre Optic Splice. Employing a visible glass capillary alignment member, that is preloaded with index matching gel, the user can inspect the fibre location during installation. The splice is tunable and reusable for most emergency or permanent installation requirements.

Overview of the installation procedure

Prepare, clean and cleave the fibre ends. The Cleave Length should be 7-9 millimetres as illustrated below

Align and butt the cleaved end faces of the optical fibres in the visible central glass guide. The moulded-in springs hold the buffers during installation and/or tuning, without the need for any extra tooling or fixturing.

To permanently secure the fibre(s), twist the grey locking nut (like a wire nut) to lock the internal Collette onto the buffer. This action is similar to a Pin Vice or Drill Chuck, as it firmly grips the buffer when the nut is tightened. It provides a higher retention that the fibre or buffer tensile strength.
