Connectors are an important connection and disconnection point. The task of the connector is to transmit optical signals and/or electrical power. The external interface is the device interface. Depending on the operating conditions, interfaces are used in protection class IP20 or in M8/Ml 2 designs for IP6X.
IEC 63171 - basic standard with all specifications and test sequences
Depending on the requirements, different PCB sockets, connectors, wall bushings, etc. are used. Here is an overview of the standards offered by members of the Single Pair Ethernet System Alliance:
IEC 63171-2
IP20 | MICE 1
The smallest SPE connectors for building and industrial cabling.
Power over Dataline (PoDL acc. to IEEE 802.3bu/cg)
Plug compatible with -5 (for use as a service interface)
