NBN Australia Trials 100 Gbps FTTH Technology on Live Network

Australian government-owned wholesale network NBN Co has achieved wholesale download speeds of 83 Gbps on the live NBN full-fibre (FTTH) access network using Nokia’s prototype 100 Gbps technology. NBN said this is the first time the prototype technology has been employed in the ‘real world’ outside of a lab setting.

Gigabit Fiber Milestone

NBN, for the first time, combined signals of 10 Gbps, 25 Gbps, 50 Gbps, and 100 Gbps on a single NBN fibre running between the operator’s exchange building and an empty FTTH-connected home. The companies claimed it was the first time this type of test – which used Nokia’s Lightspan platform – has been run outside of a lab setting.

The demonstrations showed that the fibre deployed on the NBN network has the capability to support the coexistence of multiple next-generation broadband technologies, including XGSPON, 25GS PON, 50G PON, and 100G PON.

Multi-Gigabit Possibilities

Two demonstrations were run on a single NBN fibre: The first demonstration included, XGSPON, 25GS PON, and 50G PON signals combined to achieve an aggregate Layer 1 PON speed of 85 Gbps (downstream), or Layer 2 download speeds of 71 Gbps (8 Gbps, 21 Gbps, and 42 Gbps, respectively) after accounting for protocol overheads.

In another demonstration, XGSPON, 25GS PON, and 100 gigabit signals combined to achieve an aggregate Layer 1 PON speed of 135 Gbps (downstream), or Layer 2 download speeds of 112 Gbps (8 Gbps, 21 Gbps, and 83 Gbps, respectively) after accounting for protocol overheads.
