Huawei claims breakthrough in 100Gbps-PON technology

Huawei has claimed a breakthrough in 100Gbps-Passive Optical Network (PON) optical access. The technology uses a hybrid time-division and wavelength-division architecture to support 4 x 25Gbit/s downstream rate and a 4x 10 Gbit/s upstream rate thus, according to the company, enabling 100Gbps access rate per port on existing optical distribution networks (ODNs).

“Ultra-broadband has become a transformational force, propelling the interconnection of the world forward in unimaginable ways,” Jeff Wang, President, Access Product Line at Huawei, said. “A connected world needs network support. Huawei is making continuous innovations in optical access and the breakthrough in 100G-PON technology is helping carriers construct future proof networks.”

The network infrastructure specialist also said the technology allows carriers to perform “seamless upgrades to future-proof access networks” through compatibility between 100Gbps PON and GbpsPON/10GbpsPON/40Gbps TWDM PON. The system also apparently supports back-haul for Fibre to the curb, basement or office, and mobile stations.

“Huawei are pleased to announce this highly anticipated optical access standard which expands on the existing 40G- time and wavelength division multiplexed passive optical network (TWDM PON),” the company said in a statement.

According to Huawei, the 100Gbps-PON will respond to a growing demand for home bandwidth, increasing with the usage of such technologies as cloud and smart home services, as well as streaming of 4K and 8K ultra-HD videos.

During the course of testing the technology over a 20km transmission system, Huawei claimed it was able to demonstrate it is fully compatible with other PON systems on the ODN, and that through supporting more wavelength paths the system can handle up to 200Gbps per port.
