MST155C16PDH Fiber Optic Multiplexer

1. Product Description

EZWELL MST155C Multi-service PDH Fiber Multiplexer provides ideal solutions for building fiber-based E1 and IP networks. Available as standalone units or as module for rack mount to save valuable POP space. It converts 4 to 16 E1s and 1 (or 4) Ethernet ports data to single/dual fiber signal and transmits the converted signal over the fiber cable. Some series offer additional V.35 ports to convert data from router.

Ethernet transmission utilizes one integrated 10/100BASE-TX LAN ports with 100M bandwidth maximum throughput. The Ethernet ports can operate in half or full duplex mode, and supports auto-negotiation and transparent VLAN forwarding.

MST155B series offer modular, redundant power supply and secondary link options, enhancing system reliability. The optional secondary link provides backup using automatic switch over upon main link failure.
