Product Description & Overview
This advanced optical multiplexer delivers a comprehensive telecommunications solution by integrating
four E1 interfaces with 10/100M Fast Ethernet connectivity and optional PCM digital hotline phone
capability. Engineered for carrier-grade network applications, this high-performance multiplexer efficiently
combines multiple service channels over a single fiber optic link, providing exceptional flexibility for modern
telecommunications infrastructure. The sophisticated system architecture ensures reliable transmission of
voice, data, and signaling information while maintaining complete signal integrity across extended distances.
Featuring comprehensive alarm monitoring and fault detection capabilities, this robust multiplexer enables
real-time network management and quick troubleshooting. The compact design incorporates advanced power
management technology, achieving remarkable energy efficiency without compromising performance. With
high integration levels and minimal footprint, this solution is ideal for space-constrained installations in
telecommunications cabinets, mobile base stations, and enterprise network environments.
The device supports flexible configuration options and seamless integration with existing network equipment,
making it particularly suitable for last-mile connectivity, wireless backhaul applications, and enterprise network
expansion projects. Enhanced error correction mechanisms and quality of service (QoS) features guarantee
uninterrupted operation in demanding conditions, while the extended temperature range capability ensures
reliability in various environmental conditions. This professional-grade multiplexer establishes new standards
for cost-effective multi-service transmission in telecommunications, transportation, and industrial communication
networks requiring reliable E1 and Ethernet convergence over fiber optic infrastructure.
