Single Pair Ethernet System Alliance e.V.
Description
- Semiconductor products provide the electrical interface to SPE connectors and cables. They implement the physical layer of the ISO Communications reference model. They prepare the bits that make up an Ethernet frame so they can be placed on a single balanced pair of wires that take them to other network participants.
- SPE semiconductor products conform to standards from the Institute of Electrical and Electronic Engineers (IEEE) that define how Ethernet works. There are several standards that define networks running at different speeds.
- Semiconductors products that implement SPE can perform several functions and this web page includes pointers to the different types of products. Different suppliers have product lines that work at various speeds and integrate different functions. They interoperate with each other because they implement the same standards.
- The current SPE speed grades are:
- 10BASE-T1S: Short-reach 10 Mbit/s, multidrop and point-to-point connections
- 10BASE-T1L: Long-reach 10 Mbit/s, point-to-point connections
- 100BASE-T1: 100 Mbit/s, point-to-point
- 1000BASE-T1: 1000 Mbit/s, point-point
