      At work we have this proprietary piece of hardware that has many rj45 connectors that delivers PoE and a clock pulse synced to GPS. More than once people have called me asking if this ethernet switch they found in my stash of spares is broken or something. More than once I’ve had to explain to them that what they’re holding is PoE but without the E.

          We use it to discipline and sync chip scale atomic clocks, and power them without draining their batteries. We just happen to use ethernet cables for the connection. And each clock pulse distributor is rackmounted and has 48 rj45 ports.

                WHO SHOULD READ THIS GUIDE

                This document is intended for engineers and telecommunications professionals who are designing, installing, operating, or maintaining time, frequency, and synchronization systems having a requirement for a low profile and highly precise frequency generator.

                To use this document effectively, you should have a good understanding of digital telecommunications technologies and analog frequency generation and synthesis techniques.

                Fine, I guess I’ll use it INEFFECTIVELY.
