Hi All, I thought I'd follow my comments up with information on a new cell site backhaul product launched in NZ this week.
https://sp.chorus.co.nz/product-update/launching-voluntary-mobile-access-service-mobile-sites 1 Gbps fibre tail, upgradable in the future. My best guess is that future products will be based on XGS-PON or 25G PON.
