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?
