4E1 TO ETH Converter
4E1 TO ETH Converter
This model can multiplex to 4 E1 signals for transmission over an optical fiber, resulting in reaching a longer distance without a repeaters and superior performance compared to copper media. This model 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. The 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 mircomidi or the special network. Complete alarm function for the model, it is stable and easy to maintenance, install and small in size. It has one digital service telephone.
FEATURES:
Below lists the features for this model:
- Provides 4E1 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 the local model and the remote one.
- One link of 10/100M Ethernet for option.
- One link to service telephone for duty contract for option.
- Embodies the feature of making a distinction between the remote device power fail and fiber cut by means of indicators.
- 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 19inch/ 1U mount, little volume, light weight, steady capacity and convenient setup.
