Product Description & Overview
This advanced PDH fiber optic multiplexer represents a significant 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 10/100M
Ethernet ports with 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 continuous service availability in mission-
critical applications.
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 communication capabilities for operational and maintenance purposes.
Advanced alarm monitoring and performance management systems provide comprehensive network
visibility, enabling rapid fault detection and efficient troubleshooting across all service interfaces.
Designed with power efficiency and space optimization in mind, this compact multiplexer incorporates
high-density integration while maintaining low power consumption. The robust construction ensures
stable operation in various environmental conditions, making it suitable for telecommunications
infrastructure, mobile backhaul networks, and enterprise connectivity applications. With its extensive
interface capacity and reliable fiber optic transmission capabilities, this PDH multiplexer establishes
new standards for cost-effective multi-service transport in modern network deployments requiring high-
density E1 and Ethernet convergence over protected fiber links.
