Voice Multiplexer


Voice multiplexer is so called Phone Optical Multiplexer. All Sopto PDH fiber optical multiplexers could add voice (hotline) function except fiber modems. Voice Multiplexer includes 4, 8, 16 and 32 channel voice (FXS and FXO ports) with 1, 2 and 4 Ethernet ports. The phone optic multiplexer can multiplex to E1 signals for transmission over dual fiber or single fiber, resulting in reaching distance from 2km to 120km. Two interface options: 120ohm (RJ45) and 75ohm (BNC).
