1. Product Description

MST240A series PDH Fiber Multiplexer is a series of optical and electrical transmission equipment manufactured by EZWELL with the ASIC as its core, it supports mutilple E1, support single or dual optical port, provide 1+1 service protection. MST240A is very suitable for small-capacity switch networking, user loop network, mobile communications (base station), private network, DDN, etc.

EZWELL’s MST240A series provides ideal solutions for building fiber-based E1 networks. Available as standalone unit or as module inserted in chassis to save valuable POP space. It converts 8×E1 to fiber signal and transmits the converted signal over the fiber cable.
