Product Description & Overview
This advanced PDH fiber optic multiplexer delivers a comprehensive telecommunications solution by
integrating sixteen E1 interfaces with four 10/100M Fast Ethernet ports and dual expansion slots for
flexible service configuration. Engineered for modern network applications, this carrier-grade platform
efficiently combines TDM and packet-based services over fiber optic infrastructure while maintaining
complete signal integrity and synchronization. The sophisticated system architecture ensures reliable
transmission of voice, data, and signaling information across extended distances, making it ideal for
telecommunications infrastructure and enterprise network deployments.
Featuring four fully switched Ethernet interfaces with comprehensive VLAN support, this robust
multiplexer enables sophisticated network segmentation and traffic management. The 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. Advanced alarm monitoring and fault detection capabilities deliver real-time network visibility
and rapid troubleshooting across all service interfaces, ensuring maximum operational efficiency.
The compact design incorporates high-density integration and advanced power management technology,
achieving remarkable energy efficiency in a minimal footprint. With hot-swappable module support and
extended temperature tolerance, this solution is perfect for mobile backhaul networks, industrial
communication systems, and enterprise connectivity applications. Enhanced error correction mechanisms
and quality of service features guarantee reliable operation in demanding environments, establishing this
PDH multiplexer as the optimal choice for network convergence applications requiring robust E1 and
Ethernet transmission over fiber optic links.
