I came across these the other day, they’re DC & Fibre in the same connector body.

Rather than breaking out to a fibre and an Anderson connector, you’ve got both in one connector, with provision for an extra fibre pair too, then on the other end this splits into the RRU power connector, used by Ericsson and Nokia, and a LC connector for the fibre into the RRU.

I pulled it all apart this to see how it fitted together, it looks like they’re factory pre-term cables, rather than being spliced to length, which I guess makes sense. Cool design!
