PDH Fiber Multiplexer 8E1 4GE 1+1 Protection 120km Gigabit

This advanced PDH fiber optic multiplexer represents a breakthrough in telecommunications technology,

developed using sophisticated VLSI architecture to deliver exceptional performance and reliability. The

system provides comprehensive connectivity with eight E1 interfaces, four Gigabit Ethernet ports with

full switching capability and VLAN support, plus two flexible expansion interfaces for diverse service

requirements. Engineered for carrier-class operation, the platform features 1+1 fiber protection with

automatic redundancy switching to ensure zero service interruption in mission-critical network

environments.

The integrated expansion interfaces support versatile connectivity options including RS232/RS485/

RS422 asynchronous data transmission, voice channels, E&M audio signals, switch controls, and

additional Ethernet connectivity with dedicated 2M bandwidth allocation. An optional digital business

telephone channel enhances operational communications, while the comprehensive alarm monitoring

system provides real-time network visibility across all service interfaces. The advanced management

platform enables remote configuration and performance monitoring, significantly reducing operational

maintenance costs.

Designed with power efficiency and space optimization in mind, this compact multiplexer incorporates

high-density integration while maintaining industry-leading power consumption metrics. The robust

construction ensures stable operation across extended temperature ranges, making it ideal for 5G

mobile backhaul, enterprise network convergence, and mission-critical industrial communications.

With its extensive interface capacity and reliable fiber optic transmission, this PDH multiplexer

establishes new standards for high-capacity multi-service transport in modern telecommunications

infrastructure requiring robust E1 and Gigabit Ethernet convergence over protected fiber links.
