Description
8E1 and Ethernet Fiber Optical Multiplexer is the 8E1 point-to-point optical transport equipment that uses the FPGA chips and it is easy to upgrade. It is single board structure and the largest transmission capacity is 8E1. The outer design use the standard 19 inches rack, so the volume is little, weight is light and operation is convenient and credit.
8E1 and Ethernet Fiber Optical Multiplexer, adopts the PDH fiber transmission technologies. The 2M (E1) interfaces can connect with the exchanger, light loop device and multi-diplexer directly to form the macromedia or the special network. Complete alarm function for 8E1 and Ethernet Fiber Optical Multiplexer, it is stable and easy to maintenance, install and small in size. It has one digital service telephone.
Features
Provides 8E1 transparent transmission;
Has complete alarm function and can monitor remote device status;
The supervisory control interface implements centralized monitoring and export the monitor and control information of this port and opposite port.
Support RJ11 hotline function
AC220 & DC-48V power options and the positive and negative of DC-48V can be optional because there is the self-test circuit for the polarity inside th1e device
Standard 19/9.5 inches mount, little volume, light weight, steady capacity and convenient setup
LED indicators
Support network management (SNMP).
