    The voice(FXS/FXO) phone over fiber multiplexer is point to point fiber transmitting equipment, which realizes 1 port 10/100M Ethernet and 4 channel analog voice phone over fiber transmission. Its merits include complete warning function, high integration, low consumption, stable performance and convenient usage.

  • Have two row of LED , one indicate local status, the other indicate remote status
  • the interface of lan is 10/100M ,full/duplex auto-negotiation
  • Provide two clock mode, fiber main clk and fiber line clk
  • Have three LoopBack Mode: fiber interface LoopBack(ANA)、LAN interface LoopBack(DIG)、command the remote LAN interface LoopBack (REM) 
  • Realise auto-speed setting of local device to remote device
  • Having pseudo random code test function, can used as a 2M Protocol Analyzer
  • Ethernet support N*64k rates, rate from 64k to 2048k.
  • Ethernet monitor can reset by itself,it won’t die
  • Ethernet data suggested function, real-time indicate data communication state
  • Provide 1-4 channels voice access, support calling indication
  • Voice port supports O port and S port, O port connect with PBX, S port connect with phone users
