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

Model : LNK-PDH-E4G4-2SFP Series

Product Description & Overview

This next-generation PDH fiber optic multiplexer delivers a comprehensive telecommunications solution

by integrating four E1 interfaces with four Gigabit Ethernet ports and dual expansion slots for flexible

service configuration. Engineered for modern bandwidth-intensive applications, this carrier-grade platform

supports 1+1 fiber protection with automatic redundancy to ensure zero service interruption. The advanced

system architecture efficiently converges TDM and packet-based services over a unified fiber optic infrastructure

while maintaining strict quality of service for all traffic types.

Featuring four fully switched Gigabit Ethernet interfaces with comprehensive VLAN support and traffic

management capabilities, this robust multiplexer enables sophisticated network segmentation and bandwidth

allocation. The dual expansion interfaces provide exceptional flexibility for RS232/RS485/RS422 asynchronous

data, voice channels, E&M audio signals, switch controls, and additional Ethernet connectivity with dedicated 2M

bandwidth allocation per channel. Advanced performance monitoring and fault detection systems deliver real-time

visibility into network operations across all service interfaces.

The compact design incorporates high-density integration and advanced power management technology, achieving

exceptional energy efficiency in a space-optimized footprint. With hot-swappable module support and extended

environmental tolerance, this solution is ideal for 5G mobile backhaul, enterprise network convergence, and mission

-critical industrial communications. Enhanced synchronization features and comprehensive alarm reporting guarantee

reliable operation in the most demanding network environments, establishing this PDH multiplexer as the premier

choice for modern multi-service transport applications requiring robust E1 and Gigabit Ethernet transmission over

protected fiber optic infrastructure.
