Chorus Plans Commercial Offer of 10Gbps Service from March 2019


Chorus, the telecommunication service provider in New Zealand announced that it is gearing up to provide 10Gbps fiber broadband services to the residential and small and medium enterprises. The commercial offer of the service is planned to start from the mid-March this year.

In a press release captioned “Chorus supercharges New Zealand’s broadband with 10Gbps trial”, the provider revealed that four broadband retailers  – 2degrees, Kordia, Stuff Fibre and Trustpower – have signed up to Chorus’ 10Gbps trial service with others expressing keen interest. The trial service will be available in selected areas of Auckland and Wellington, initially for 30 residential customers.

Chorus will deliver 10Gbps service using Nokia is built in collaboration with Nokia using their XGS-PON fiber solution.

What is XGS-PON?

In a blog post, Ana Pesovic explains the background of XGS-PON;

In the drive towards NG-PON (another favorite acronym), the next generation of ultra-fast broadband, we have explored various paths. In 2010, XG-PON became the first NG-PON technology to be standardized, providing 10/2.5G asymmetric bandwidth. But then the industry moved on to NG-PON2 and in 2013 we standardized TWDM-PON to include both asymmetrical 10/2.5G and symmetrical 10/10G, as well as multi-channel and tunable wavelengths. This became the basis for XGS-PON, adopted in 2017, which is basically TWDM-PON minus multi-channel and tunability. So rather than XGS-PON being an extension of XG-PON, it is, in fact, a contraction of TWDM-PON. And that makes a lot of difference for operators looking to upgrade their broadband networks.

XGS-PON is an NG-PON technology that supports symmetrical fiber services of up to 10Gbps downstream and upstream, deployed over Chorus’ existing nationwide fiber broadband infrastructure. The new service co-exists with existing fiber services making it a natural evolution for those looking for even faster plans with an easy upgrade path.

The demand for greater internet data bandwidth from residential as well as enterprise customers have led to the development of new transmission technologies and standards. Ultra-high definition video, creative media services, advanced gaming, increased home working and dramatic proliferation of connected devices in homes are all contributing to the need for greater capacity. ITU-T has devised standards for networks to meet the bandwidth demands rising from the applications in the market.

ITU-T, the international organization engaged in telecommunication standardization has come up with ITU-T G.989.2 Recommendations that specifies the physical media dependent layer requirements for a passive optical network system with a nominal aggregate capacity of 40 Gbps in the downstream direction and 10 Gbit/s in the upstream direction. This is termed as NG-PON2.

Networks based on NG-PON2 standards would be flexible optical fiber access networks that would be capable to support the bandwidth requirements of mobile backhaul, business and residential services evolving with the appearance of IoT and 5G.
