Huawei Technologies Co Ltd. claims to have produced the industry’s first 40G PON prototype. The system was jointly tested and certified by Huawei and the China Telecom Beijing Research Institute earlier this month.
The 40G PON system is backwards compatible with legacy GPON/XG-PON optical distribution networks, but scales up capacity to 40 Gbps downstream and 10 Gbps upstream. The system also supports optical splitting ratios of up to 1:512 and a transmission reach of 20 km.
Huawei says its 40G PON system will enable telecom operators to integrate future upgrade cycles into 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 40G PON system is highly compatible with existing GPON and XG-PON systems and its transmission convergence layer maximally leverages existing GPON and XG-PON structures," said Dr. Frank J. Effenberger, Huawei’s chief optical access technology expert. "We are pleased to note that Huawei’s solution has gained wide-ranging support from international standardization organizations like FSAN and ITU-T."
Earlier this year Ericsson touted a 40G PON system, but this is based on WDM-PON technology resulting from its joint venture LG-Ericsson (see "Ericsson launches 40-Gbps WDM-PON platform").
