About this installation instruction

This installation instruction describes the installation of the fiber indexing terminal of both housings, the DLX connector
housing and the full size hardened connector housing, and their different applications: the standard indexing terminal
with splitter (1:4 or 1:8), the indexing only terminal, the branch terminal and the multi-use terminal.
The instruction will explain how to handle the stubbed cable, how to mount the terminal in different situations (hand
hole, pedestal, pole and aerial), how to connect and maintain the different connector types (DLX, full size hardened
connector and HMFOC) and how to test the installed chain of terminals.
