Product Description

1. Product Overview

This field assembly fast connector (also called quick-install fiber connector) is a pre-polished mechanical splice connector designed for on-site FTTH and FTTX deployment. It eliminates field polishing, epoxy glue and fusion splicing, enabling complete fiber termination within 2 minutes with only basic hand tools, greatly reducing on-site construction time and overall engineering cost.

All ferrule end faces are factory pre-polished, removing the need for polishing consumables at construction sites. It adopts precision molded V-groove mechanical alignment principle without epoxy adhesive for fiber core docking. The assembly process is simple with stable connection performance, and can be operated in narrow and complex environments such as utility poles and manholes without extra operating space. It effectively reduces connection failure rates caused by human operation errors during field wiring and supports quick cable re-termination.
