30Voice Analog Phone Fiber Multiplexer

The 30 Channel voice multiplexer provide a method of multiplexing up to 30 analog (POTS) channels over a single pair of multimode or single mode fibers. The voice fiber multiplexer solves the problem of limited available fiber, reduces equipment space and lowers overall equipment costs.
In addition to voice(POTS), the voice multiplexer provides four 10/100 Base-T Ethernet ports and four RS-232 ports and four channel E1 ports. All ports operate simultaneously over the fiber optic cable, and may be used with leased lines to build up private networks and private telephone networks.
Its merits include complete warning function, high integration, low consumption,stable performance and convenient usage.
The 30voice(FXS/FXO) phone over fiber multiplexer can be managed by SNMP management,user can monitor kinds of devices’ operation status easily.The device can support AC220V(110V) or DC48V power,or duoble power.
