Before the editor introduced the detailed classification of optical transceivers for everyone, I believe that many friends who have seen it are familiar with the pdh optical transceivers, but do you still know the function and characteristics of pdh optical transceivers? Today, the editor of Feichang Technology Let's introduce the function and characteristics of the pdh optical transceiver in detail for everyone, and those who are interested will come and have a look!
Definition of
PDH optical transceiver : PDH optical transceiver is a 120-channel photoelectric integrated transmission device composed of very large-scale integrated circuits. It is generally used in paired applications, also called point-to-point applications. The capacity is generally 4E1, 8E1, 16E1; suitable for small-capacity switches Group network, user loop network, mobile communication (base station), private network, DDN network, etc.
The main function of PDH optical transceiver:
1. Provide 8 E1 service ports, all-digital clock recovery and smooth phase lock technology;
2. Provide RS232 network management interface, support unified-one-network management;
3. Provide RS485 network management cascade interface, multiple devices can be managed through the same terminal network;
4. Dual power supply, mutual hot backup, optional AC220V, DC48V, etc.;
5. Provide complete local/peer end alarm monitoring, three-color light indication;
6. Support local/remote E1 trick loopback;
7. Provide a transparent RS232 data channel, with a rate of 300-19.2Kbit/s adaptive.
The characteristics of PDH optical transceiver:
Its main characteristics are: using super large-scale integrated chip, with low power consumption and high reliability. Provide E1 remote loopback test function, easy to maintain. 120 provides 4 E1 channels; it has a complete alarm function, which can display local and remote alarms. Alarm information (including power failure alarm) can be reported to the peer through the network management channel. Using transceiver integrated optical devices, stable and reliable working performance. The single-board design of the whole machine is small in size and easy to use.
