DESCRIPTION: 
    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.

FAQ:

Question1: Can Baudcom’s phone over fiber multiplexer support FAX transmission?

Answer:  Yes, the voice phone fiber mux device can support voice(FXS/FXO) or FAX  over fiber transmission. The voice fiber mux device also can support  voice transmission with ethernet data service.

Question2: Can Baudcom’s phone over fiber multiplexer support ADSL transmission?

Answer: For the modulation is different, the voice phone fiber multiplexer can not support ADSL service.

Question3: What is maximum phone line length between telephone and the voice fiber multiplexer?

Answer: The device can support maximum line length is 1KM.  

Question4: Do Baudcom's POTs phone fiber multiplexer support caller ID display?

Answer:  The POTs phone fiber multiplexer device support caller ID display  function,phone receiver can get the caller ID information.

Questio5:  Can it support 4 wires audio channel (TX and RX), instead of FXO/FXS? Moreover,may I know the audio's frequency response supported in the voice mux device?

Answer: The POTs fiber multiplexer can support 2wire or 4wire E&M, the audio's response frequency is 20-7k.

Questio6:  Can the analog phone fiber multiplexer support the payphone (coin phone)?

Answer:  The payphone have two types,one is reverse polarity charge  payphone,another is pulse charging payphone.The reverse polarity charge  can be supported.
