PDH optical transceiver (Plesiochronous Digital Hierarchy, quasi-synchronous digital series) is a small-capacity optical transceiver, generally paired applications, also called point-to-point applications, and the capacity is generally 4E1, 8E1, 16E1. Next, JHA TECHNOLOGY will introduce the advantages of pdh optical transceivers in detail, let’s take a look!
1. A unified bit rate and a unified interface standard provide the possibility for interconnection between devices from different manufacturers.
2. Network management capabilities have been greatly enhanced.
3. Put forward a new concept of self-healing network. The ring network form with self-healing protection capability composed of SDH equipment can automatically resume normal communication through the self-healing network when the main signal of the transmission medium is cut off.
4. Byte multiplexing technology is adopted to make the upper and lower branch signals in the network very simple.
Because PDH has the above-mentioned remarkable advantages, it will become one of the basic technologies to realize the information superhighway. But on the branch roads and fork roads connected with the information highway, PDH optical transceiver equipment will still be useful.
The 8E1 PDH optical transceiver uses a large-scale integrated circuit with independent intellectual property rights, and applies time division multiplexing technology to mix and encode E1 signals and transmit them on a pair of optical fibers. Products designed using this chip adopt a single-board design, with high integration, small size, low power consumption, reliable work, and easy installation and use.
