Overview
     The light transmission apparatus MDO-MST mini multi-service transmission equipment is manufactured based on our proprietary purpose-built integrated circuits. It integrates the traditional 2M E1, V.35 data,RS232 data, 10/100Base-Tx, in one equipment so that it can operate both high-speed digital service and traditional TDM service in one pair of Fiber.
