Overview360 POTS (FXO/FXS) over Fiber multiplexer is a kind of point-to-point fiber transmission device. It could support 360 phone lines POTS (FXO/FXS), 1~4 E1 and  1~4 100M Ethernet transmit over one Optical cable. the transmit distance can arrive at 2km,20km,40km,60km,80km,120km. It has been made up of 12 unit business card of 30 POTS(FXO/FXS) and 1 central management card,2 power card . This 360 POTS (FXO/FXS) over Fiber multiplexer has complete alarm function, low consumption, stable performance and convenient usage.Feature
