Functions

The voice over fiber multiplexer is point to point fiber transmitting equipment, which realizes 1~8 channelvoice (FXO, FXS) POTs phone over fiber and  4 E1,4*100M Ethernet, 4 channel RS232 for option. Its merits include complete warning function, high integration, low consumption, stable performance and convenient usage.
