Overview( IRMIDAS- MDO-DF480E4 ) 

The light transmission apparatus MDO-DF480E4 1+1 dual optical ports

multi-service transmission equipment is manufactured based on our

proprietary purpose-built integrated circuits. It integrates the traditional 2M

E1, 4*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 restorationmechanism enables the equipment to achieve 1+1 protection for MDO-

DF480E4 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.
