The light transmission apparatus MDO-240E multi-service transmission equipment is manufactured based on our proprietary purpose-built integrated circuits. It integrates the traditional 2M E1, 10/100Base-Tx (max bandwidth: 100M), in one equipment so that it can operate both high-speed digital service and traditional TDM service in one pair of Fiber. The advanced dual-light-beam switching and restoration mechanism enables the equipment to achieve 1+1 protection for MDO-240E transmission equipment can also provide centralized rack structure for easy maintenance as well as plug and play, and at the same time, provide complete network management function.
