10BASE-T1L Single-Pair Ethernet Cable Reach and Link Performance (Download)
As 10BASE-T1L Ethernet emerges across various industries, more applications come to light, each bringing new challenges to be addressed to successfully deploy the technology. A common requirement is support for a wide range of cable types. In some cases, these cables have been used in legacy communication systems and are often found in existing installations. The flexibility of the cable definition in the 10BASE-T1L standard creates an advantage over other technologies by allowing for the reutilization of such cables.
This flexibility raises common questions, such as whether 1 km can be achieved with any cable or whether performance is the same independent of the type of cable. Link performance and reach depend on the cable’s characteristics, which, in turn, depend on the construction of the cable. This article summarizes the cable characteristics relevant to this technology, describes the dependency of cable reach as a function of these characteristics, and provides a list of cables that have been tested.
