New fibre technology takes nbn to 10 Gbps
nbn has recently partnered with Nokia to trial new fibre technology NG-PON2, which could help nbn deliver symmetrical speeds of 10 Gbps to its Fibre-to-the-Premises (FTTP) end user premises – 10 times faster than the current top FTTP speeds of 1 Gbps.
A future deployment of NG-PON2 could also benefit end users connected to retail services over nbn’s Fibre-to-the-Basement (FTTB) and Fibre-to-the-Curb (FTTC) networks – through new technologies such as G.fast or XG.FAST – and could also provide extra capacity in the fibre that supports nbn’s HFC and Fixed Wireless networks.
During recent trials in Melbourne, NG-PON2 delivered peak trial lab speeds of 102 Gbps – generated from 40 Gbps symmetrical speeds on Time and Wavelength Division Multiplexing (TWDM-PON) technology, 10 Gbps symmetrical on XGS-PON and a further 2.5 Gbps on nbn’s current Gigabit Passive Optical Network (GPON) technology.
nbn is currently offering wholesale maximum speeds of up to 1 Gbps to retail service providers and expects its current GPON-based FTTP network will be available to up to 2.5 million premises by 2020.
NG-PON2 is the next-generation fibre technology standard that will, over time, augment the GPON technology currently offered to retailers selling services over the nbn FTTP network.
Using TWDM technology, which supports between 4-8 wavelengths on a single fibre, NG-PON2 is expected to deliver initial symmetrical speeds on FTTP up to 10 Gbps and potentially well beyond as the technology develops.
