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.
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.
No. Closest thing we have is a Germany Cabinet, as we bought a large set from a German manufacturer last year. It's more high end than our everyday stuff, and mostly use it when we have people over and birthdays and stuff.
When I hear "China Cabinet" I think of somewhere easily visible and with glass doors so that they're also on display when not in use. Ours ate hidden in the back along with other stuff we don't use all that often.
Nothing bad with palm oil in itself, as long as its cultivation isn't replacing a vital food crop in its originating community.
