Product Description & Overview
This advanced PDH fiber optic multiplexer delivers a comprehensive telecommunications solution by
integrating four E1 interfaces with four 10/100M Fast Ethernet ports and dual expansion slots for flexible
service configuration. Engineered for mission-critical network applications, this carrier-grade multiplexer
supports 1+1 fiber protection switching with automatic redundancy to ensure uninterrupted service continuity.
The sophisticated platform efficiently combines multiple service channels including voice, data, and signaling
over a single fiber optic infrastructure while maintaining complete signal integrity.
Featuring four switched Ethernet interfaces with comprehensive VLAN support, this robust multiplexer enables
sophisticated network segmentation and traffic management. 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 2M bandwidth allocation. Advanced alarm monitoring and fault detection
capabilities allow for real-time network management and rapid troubleshooting across all interface types.
The compact design incorporates high-density integration and advanced power management, achieving remarkable
energy efficiency in a minimal footprint. With hot-swappable module capability and extended temperature tolerance,
this solution is ideal for telecommunications infrastructure, mobile backhaul networks, and industrial communication
systems. Enhanced error correction mechanisms and quality of service features guarantee reliable operation in
demanding environments, establishing this PDH multiplexer as the optimal choice for modern network convergence
applications requiring robust E1 and Ethernet transmission over protected fiber optic links.
