Huawei launches 40G PON prototype

New system uses wavelength division multiplexing technology that allows a 40Gbps downstream transmission rate, with no change to legacy GPON/XGPON optical distribution networks

By CBR Staff Writer

Information and communications technology (ICT) offerings provider Huawei has launched, what it claims, the industry’s first 40G PON (Passive Optical Network) prototype.

The 40G PON system uses wavelength division multiplexing technology that allows a 40Gbps downstream transmission rate and a 10Gbps upstream rate, with no change to legacy GPON/XGPON optical distribution networks (ODN), said the company. The system also supports a 1:512 optical splitting ratio and a transmission reach of 20 kilometers, it added.

Huawei’s 40G PON system is expected to enable telecom operators to integrate future upgrade and evolution initiatives with existing GPON deployment plans, offering them more control over the total cost of operation throughout the entire life cycle of an optical access network.

Huawei’s Access Network Product Line president You Yiyong said as telecom operators worldwide rush to implement optical fibre deployment strategies, a key question is how to build sustainable optical access networks that can evolve and grow into the future.

You Yiyong continued, "Huawei continually strives for customer-oriented innovation in the optical access sector and to provide telecom operators worldwide with premium products and future-proof solutions that help them increase their return on investment and grow in a fast changing world. The launch of the first 40G PON prototype is testament to this commitment."

The company said that the 40G PON system was jointly tested and certified by Huawei and the China Telecom Beijing Research Institute earlier this month.

"Huawei’s 40G PON system is highly compatible with existing GPON and XGPON systems and its transmission convergence layer maximally leverages existing GPON and XGPON structures," said Dr. Frank J. Effenberger, Huawei’s chief optical access technology expert.
