IDM-120NET can multiplex 4×E1+2×10/100BaseT in one fiber channel. The BNC model provides unbalanced 75 Ohm coaxial connectors while the RJ-45 model provides balanced 120 Ohm connectors over twisted pair wiring. IDM-120NET is standalone and rack mountable. Dual AC&DC power supplies are available. IDM-120NET is supposed to be applied in point-to-point applications. The optical interface supports simple ALS function. The code of E1 interface is HDB3 which meets all the international standards. It also has perfect monitoring and alarm function, low power consumption and stable performance.
