EMUX200ESX

1：General Overview

EMUX200ESX Integrated Service Optic Access Equipment is developed and produced independently by Easy Broadbａnd Technology (Beijing) Co., Ltd with its own ASICs. The Ethernet signal and telephone signal are mixed and encoded and transmitted on a pair of optical fibers by adopting time division multiplexing technology. Thus realizing telephone service transmission. The transmission channel includes optical transmission channel and VF transmission channel. This device adopts 19"*2U design, high integration, low power consumption, reliable operation, easy to install and use.
