The TBC-MC3742E-D20 Series Ethernet optical switch has 4*10/100/1000M standard SFP socket and 2 RJ45 ports Switch converts 4 independent 10/100/1000Base-TX twisted pair electrical signals and 2*10/100/1000M optional adaptive RJ45 interface.
Do not use a fixed RJ45 electrical port, then the switch is all four SFP Gigabit optical switches. Users can choose different SFP modules according to their needs, such as multi / single mode, single / dual fiber, single mode 550m ~ 120Km and so on.It can achieve 1000M Ethernet optical, seamless connection between electrical signals. Than the fixed optical module gigabit switch to better meet the different needs of different users. Switching chip using the latest American IC, stable performance, good quality, easy to use, with a high cost. For small fiber Ethernet and fiber optic networks with special needs.
