Product Description

1. Product Overview

This fiber access terminal box serves as the cable termination unit for feeder optical cables to interconnect with drop cables in FTTx communication networks. It integrates fiber splicing, optical splitting and cable distribution functions, providing reliable physical protection and standardized cable management for FTTH network deployment, supporting access for up to 24 household subscribers.

2. Core Product Features

1. Fully enclosed integrated cabinet structure

2. Cabinet material: PC+ABS composite material; excellent moisture-proof, waterproof, dust-proof and anti-aging performance, with IP65/IP66 ingress protection rating

3. All-in-one functional design: integrated clamping structure for feeder cables and drop cables, dedicated positions for fiber splicing, fiber fixation, fiber storage and cable routing

4. Independent separated routing channels for trunk cables, fiber pigtails and patch cords to avoid signal interference and cable winding; compatible with miniature PLC optical splitters, convenient for daily maintenance

5. Flip-up distribution panel design; feeder cables can be routed through reserved side ports, simplifying field installation and later maintenance operations

6. Dual installation modes: wall-mounted and pole-mounted, applicable for both indoor and outdoor deployment scenarios
