Product Description

1. Product Overview

This pigtail is assembled with FTTH drop cable, designed as the terminal connection component in FTTH networks. It is widely applied for connections between faceplates, terminal boxes, ONUs, and other communication equipment, supporting direct indoor cabling to end users. The fiber is centrally positioned with two parallel FRP strength members and an LSZH outer sheath. Custom connectors are available upon request.

2. Key Features

• Excellent mechanical and environmental performance

• Simple structure, lightweight, and highly practical

• Low-smoke zero-halogen (LSZH) and flame-retardant sheath

• Special groove design for easy stripping, splicing, installation, and maintenance

• Dual parallel FRP strength members for superior anti-electromagnetic interference and crush resistance

• Low-bend-sensitivity fiber for high bandwidth and stable transmission
