What are the differences between audio fiber optic transceivers and telephone fiber optic transceivers?
Release time:
2025-05-16
Audio fiber optic transceivers are derivatives of video fiber optic transceivers, often used in security systems to transmit video from surveillance cameras and audio from listening devices; while telephone fiber optic transceivers, known as PCMs, are traditional telecommunications products, such as transmitting 30 lines of program-controlled telephones via fiber optics.
For audio Optical terminal and telephone optical terminal Are they the same? What are the differences?
In fact, the mechanisms of audio optical terminals and telephone optical terminals are different. Many people think that audio optical terminals and telephone optical terminals are the same, and they don't understand where they are different.
So what are the differences between audio optical terminals and telephone optical terminals? Next, let the editor make a simple introduction for everyone based on the differences between audio optical terminals and telephone optical terminals.
Differences between audio optical terminals and telephone optical terminals
1. Audio optical terminal is a derivative of video optical terminal, often used in security systems, used to transmit monitoring camera video and monitoring head audio; while telephone optical terminal is called PCM , which belongs to traditional telecommunication products, such as transmitting 30 lines of program-controlled telephones through optical fibers.
2. If the traditional 2M network needs to transmit video, it needs to be equipped with an audio codec, so the audio can be transmitted through SDH network transmission
3. Audio optical terminals are distinguished by the number of channels, with one, two, four, eight, and sixteen channels, while telephone optical terminals are superimposed on the same motherboard. For example, the price difference between 6-channel and 7-channel telephones on an 8-channel motherboard is not large, and the price difference between 25-channel and 30-channel telephones on a 30-channel motherboard is not large.
4. Both audio optical terminals and telephone optical terminals can be stacked with Ethernet, industrial control data, etc., depending on the specific practices of different manufacturers. Guangzhou Yinxun's audio and video optical terminals can be added with Ethernet, telephone, alarm switch quantity, etc., while telephone optical terminals (ie PCM) can be added with 100M Ethernet, 2/4-line audio, 2/4-line E/M, military magnets, RS232 data, etc.
5. One fiber can transmit up to 128 channels of uncompressed video, and one fiber can transmit up to 480 channels of telephone.
The above information is a simple introduction made by the editor based on the differences between audio optical terminals and telephone optical terminals. I believe that everyone has a certain understanding of the differences between audio optical terminals and telephone optical terminals through the above information.
