What are the advantages of PDH video optical terminal? We use video optical transceiver, communication fiber and other machinery to achieve fast and long distance transmission of information, different video optical transceiver has different characteristics, we can choose different video optical transceiver according to different situations.

Let's see what advantages PDH video optical terminal has?

1. The E1 remote loopback test function is provided for easy maintenance.

2, using very large scale integration chip, with low power consumption, high reliability characteristics.

3. Complete alarm function, showing local and remote alarms.

4. 120 Provides four E1 channels.

5, the use of transceiver integrated optical devices, stable and reliable performance.

6. Alarm information (including power failure alarms) can be reported to the peer end through the NMS channel.

7, the machine veneer design small volume, easy to use.
