Model : LNK-E32G4 Series
Product Description & Overview
The 32E1 + 4GE PDH Multiplexer (1+1 backup Optic Fiber) represents a robust fiber optic transmission
platform engineered for mission-critical network applications. Utilizing advanced VLSI technology, this
system delivers carrier-grade reliability through its integrated 1+1 optical fiber protection mechanism,
ensuring uninterrupted service continuity with automatic switchover capabilities when link failures are
detected. The multiplexer provides comprehensive interface support with 32 full-duplex E1 ports
compliant with G.703 standards and 4 auto-negotiating 10/100/1000M Gigabit Ethernet interfaces
operating at wire-speed throughput.
This high-capacity multiplexing solution incorporates sophisticated switching capabilities across its four
Ethernet ports, supporting VLAN configuration for secure network segmentation and optimized traffic
management. The platform's flexibility is further enhanced through dual universal expansion interfaces
that accommodate various service requirements, including asynchronous data transmission (RS232/
RS485/RS422), dry contact alarm signals, and optional PCM digital business telephone channels for
integrated voice communication.
Engineered for operational excellence, the system features comprehensive performance monitoring
and fault detection systems that provide real-time status reporting for both local and remote units.
The device's high-integration design ensures exceptional stability with minimal power consumption,
while its compact form factor makes it ideal for space-constrained installations in telecommunications
cabinets, mobile base stations, and enterprise network environments. This multiplexer is particularly
suitable for applications requiring high-availability transmission, including mobile backhaul networks,
enterprise WAN extensions, and mission-critical infrastructure communications where zero-downtime
operation is essential.
