That is a Cinch-Jones 300-Series connector, universally called a "Jones Plug". Beau makes something similar. Here is the Mouser version of the catalog: https://www.mouser.com/datasheet/2/...

Identify this cable connector

Looks like an Adam Tech MTD series connector. Though without the dimensions it's hard to tell for sure. Also - according to the datasheet - the 18 AWG version should be orange.

Does anyone recognize this schematic symbol? (Ethernet connector)

FL11 is likely just a ferrite bead. But as it is greyed out and reads "DNI" it means it is not populated in the circuit, so 1V8 would not be connected to connector. The diagram is only an ...
