 16voice phone fiber multiplexer is point to point fiber transmitting equipment, which is designed on large scale integrated circuit, realizes 1~4 E1 circuit, 1~4channels 10/100/1000M Ethernet, 16 channel voice (FXO/FXS) and 1~2 channel RS232. Its merits include complete warning function, high integration, low consumption, stable performance and convenient usage. In the 16channel voices, the FXS and FXO can be combinated freely, for example,8*FXS+8*FXO.


  • Provides1~ 4 channel E1/ G.703 for option;
  • provides 1~4 channel 1000M (line) Ethernet ports for option;
  • provides 16 channel voice port, FXO and FXS for option;
  • provides1~2 channel RS232, rate supports 300-15200 bps for option;
  • Ethernet port 10/100/1000M, full/half duplex auto-adaptable and supports VLAN;
  • Ethernet port supports AUTO-MDIX (twisted cable and straight cable auto-adaptable);
  • 1-16 channel voice connection, supports calling indication;
  • Configuration: point to point;
  • Voice port supports O port and S port, O port connects switch and S port connects user’s phone;
  • Optical interface supports SC/FC interface and supports single fiber interface

  • Power can support DC48V or AC220V or AC+DC
