1. There are the following types according to the current light end machine equipment in the application field:

1. Telecommunications light -end machine:

Each basic channel of its light -end machine is 2m, commonly known as 2M -ending machine. Each 2M channel can transmit 30 telephones or 2M bandwidth network signals per 2m channel. It is just a fixed bandwidth channel. The protocol supporting agreement is the G.703 protocol, which is mainly used in the field of telecommunication communication in a fixed bandwidth.

2. Monitoring of light -end machine:

It is used to transmit video signals (such as video signals output by ordinary cameras), and can also assist the transmission of audio, control data, switching signals, and Ethernet signals. field;

3. Light -end machine for radio and television:

It is used to transmit radio frequency signals, and its terminal is not transmitted. It directly branches in the light road. It can be used by a transmitter to multiple receivers.

2. What areas are the general application application?

1. The transmission signal of the primary toll station is far from the previous level and the provincial toll station monitoring system. The transmission distance is far away. In order to ensure the full -time transmission signal and video signal, the light -end machine is the best transmission device for transmission signal.

2. The light -end machine has the characteristics of transmission information in the state of high -voltage power systems, and the effect of video transmission will not be affected.

3. The transmission of video capture and signal lights In a long distance, it is necessary to ensure that the signal is not disturbed at the same time. The signal transmission is omnidirectional.

4. The main monitoring of community monitoring is where the population is relatively large. In order to ensure that the video signal the video signal transmits high speed, the signal transmitted by the optical machine can ensure that the video signal is transmitted to the monitoring center in order Take action and guarantee evidence.
