Default Openroach turbo master baiting too busy to install fiber

So just remind everyone - what data rate can be [readily] achieved down a single fibre in Tbps?

WTF would anyone be daft enough to install 3456 core fibre cables anywhere [when just a few (for redundancy) would do]?

Hint - some clues here : -

Openreach use passive optical splitters so they don't have to have
powered kit scattered about. The bitrate is limited by what the customer
site fibre modems can handle - way below the fibre's limit.


Interesting - 10Gbps fibre modems are as opposed to for 1Gbps.

Can they use a diffraction grating to extract multiple beams from the same fibre?
