Overview
The light transmission apparatus MDO-120G 1+1 dual SPF optical ports backup multi-service transmission equipment is manufactured based on our proprietary purpose-built integrated circuits. It integrates the traditional 4 channels E1, 1000Base-Tx, in one equipment so that it can operate both high-speed digital service and traditional TDM service in 1+1 SFP protecton Fiber link. It can widely used in many 1000M Ethernet network. Features
◆ Provide 1+1 dual SFP fiber insert slots, can realized bakcup protection
◆ Offering 4E1 (2.048Mbps) interfaces
