Telstra backbone network arm, InfraCo, said it has opened up its Intercity Fibre Network (IFN) that is under construction currently for pre-orders.
The telco is holding out the benefit of securing capacity early on some of the busiest routes in Australia, with Dark Fibre, Direct Spectrum and Wavelength solutions in the IFN product suite.
Diversity options include one pair (two fibres) single path in a route (non-diverse), and two pairs (four fibres) with two geographical paths on a route.
The IFN Express with Ultra-low loss uses the 1550 nanometre Conventional band and 1625 nm Long wavelength band; meanwhile, the low-loss Foundation service option uses full spectrum bandwidth.
For the physical fibre-optic cabling, Telstra uses Corning's SMF-28 for the Ultra-low loss link, and Prysmian BBA2 for the Foundation network.
Wavelength capacity based on Ciena's 6500 WaveLogic 5 Extreme device is 43 600 gigabits per second optical channels, for a total of 25.8 tera bits per second; in the L-band, the 42 600 Gbps channels can provide 24.2 Tbps over the IFN.
InfraCo said it has lready laid more than 2800 kilometres of IFN fibre into the ground.
Telstra said it will add up to 20,000 km of new route sheath to its national fibre network by 2027.
