16FXO/FXS+4E1+4FE+4*RS232/422/485 Fiber Multiplexer

View : 730
Type : multi service over fiber mux
Description :

This product provides 16 channels telephone, 4 channels E1 interface, 4 channels 10/100M Ethernet interface (Wire Speed 100M) and 4 expansion interface.


This product provides 16 channels telephone, 4 E1 interfaces, 4 10/100M Ethernet ports (Wire Speed 100M), and 4 expansion ports. The 4 Ethernet ports are switch interfaces, which can support VLAN. 4 expansion ports can be used as the transmission channel of RS232/RS485/RS422 asynchronous data, voice signal, 2/4 wire E&M audio signal, dry contact signal, and Ethernet signal (Bandwidth 2M). Its application is very flexible.

E1 interface complies with the G.703 recommendation, utilizing fully digital clock recovery and smooth phase-locked loop techniques.

Voice ports support FXO/FXS, EM2/4 audio, and Magnet Telephone Interfaces. The FXO port is connected to a PBX, while the FXS port is connected to the user’s telephone set.

Voice port supports caller ID display, reverse polarity charging, and fax function.

The telephone interface supports the mutual dialing functionality between two sites.

It provides 4 extended interfaces, which can be used to expand 1-4 channels of asynchronous data transmission, such as RS232/RS485/RS422/TTL, or 1-8 channels of dry contact signals, etc. 

The Ethernet interface supports 10/100M, half/full duplex auto-adaptable, and supports VLAN.

The 4 ports Ethernet can be used as switching ports and support VLAN partition. They can also be configured as 4 logical channels for network isolation.

Ethernet interface can support AUTO-MDIX (crossed line and straightly connected line self-adaptable).

The telephone interface is equipped with lightning protection that meets the GB/T17626.5 (IEC61000-4-5) standard for short-circuit current wave of 10/700μs and can withstand a peak output voltage of 6KV under open circuit conditions.

The transmission distance is up to 2-120Km without interruption.

AC 220V, DC-48V, DC24V can be optional.
