Product Description

1. Product Overview

This fiber access terminal closure is a high-density outdoor fiber distribution unit for next-generation FTTx networks, designed for FTTH (Fiber to the Home) and FTTB (Fiber to the Building) deployment. It provides integrated protection and centralized management for all passive optical components inside, realizing fiber splicing, optical splitting and user cable termination within limited installation space. Two installation modes are supported: wall-mounted and pole-mounted.

2. Core Structural & Performance Features

1. Environmental Protection Grade: IP65 waterproof and dustproof enclosure, fully adapted to outdoor harsh environments.

2. Mechanical Impact Resistance: IK10 anti-impact rugged housing, strong anti-collision and anti-aging capacity.

3. Cable Port Configuration:

￮ 4 round feeder cable input ports

￮ 16 drop cable output ports with matched adapters for user patching

4. Fiber Protection Design: Internal fiber routing ensures fiber bend radius ≥40mm to avoid signal attenuation caused by excessive bending.

5. Splicing Tray Structure: Flip-up, rotatable and detachable splice trays for convenient fusion splicing operation; trays support 1×8 or 1×16 PLC splitters as optional configuration.

6. Cable Sealing System: Full mechanical sealing structure, compatible with mid-span cable entry for on-site cable cutting & access.

7. Opening & Locking: 180° full opening design with buckle lock, easy internal operation and anti-theft protection.

8. Deployment Advantages: Plug-and-play modular design, convenient on-site maintenance and capacity expansion.
