8E1+Ethernet PDH Fiber Optical Multiplexer
DESCRIPTION
This device provides 1-4Channel E1 interface, master optical fiber interface and backup optical fiber interface, 1-4Channel 10M/100M Ethernet interface (Line Rate 100M) and 2 expansion interface. 4Channel Ethernet interface is switch interface, can support VLAN. 2 expansion interface can be used as the transmission channel of RS232/RS485/RS422 asynchronous data, voice signal, 2/4 line E&M audio signal, switch signal, Ethernet signal (Bandwidth 2M). It is very flexible. It has alarm function. The work is reliable, stable, and low power consumption, high integration, small size.
FEATURES
n 1+1fiber line protection: double port protection.When one of the fiber failure, can be guaranteed without interruption of service;
n Provides 8 E1 transparent transmission ;
n Provide Console manage interface(RS232)
n Provide4*10/100M line Ethernet channel,support mutual negotiate, Ethernet bandwidth is set on base on multiple of 32K.;
n Provide one hot-line channel for option;
n The rate of optical port is 155/350Mbps, transmission range can reach 25KM, 40KM, 60KM, 80KM or 120KM;
n E1 interface code is HDB3,E1 vibration characteristic conforms to ITU-T G.703,G.823 and G.742;
n Ethernet port supports full/half duplex, 10/100M auto-adaptable;
n Ethernet port supports VLAN function and has 4 division mode for user selection(If the order device has four Ethernet ports,the function is ok);
n Ethernet package size support 1916 byte;
n Has complete alarm function and can monitor remote device status;
n Supports E1 loop from remote so as to detect and manage device conveniently;
n The combination AC220V and DC-48V for redundant
