4Voice(FXS/FXO) over Fiber,phone over fiber multiplexer

Functions
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.
