4E1 10 100M Ethernet fiber multiplexer is the 4E1 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 4E1. The outer design use the standard 19 inches rack, so the volume is little, weight is light and operation is convenient and credit. 4E1/8E1/6E1 fiber optical multiplexer, is use the PDH fiber transmission technologies. The 2M (E1) interfaces can connect with the exchanger, light loop device and multi-diplexer directly to form the mircomidi or the special network. Complete alarm function for 4E1/8E1/16E1, it is stable and easy to maintenance, install and small in size. It has one digital service telephone.
- Offer 4 X 2Mb/s digital interfaces
- The supervisory control interface implements centralized monitoring and export the monitor and control information of this port and opposite port.
- One link to service telephone for duty contract
- 220VAC & -48VDC 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 rack, little volume, light weight, steady capacity and convenient setup
- Digital clock recovery circuit and digital smooth DPLL adopted for 2.048Mb/s port
- LED indicators
- Has 1+1 fiber protection for optional
- Power supply redundancy : AC220 and DC-48V or DC-24V combination
