Huawei taps Anritsu SDH/SONET analyzer for 40G subsea deployment

NOVEMBER 21, 2007 -- Anritsu Company's (search for Anritsu) today announced that its MP1595A 40G SDH/SONET analyzer was used by Huawei Technologies Co., Ltd. (search for Huawei) as part of the deployment of a native 40-Gbit/sec capacity over a subsea span between Boston and Halifax, Nova Scotia on the Hibernia Atlantic cable system.

The MP1595A was used by Huawei to verify the performance of its 40G transponders, which were designed into over 400 miles of cable to increase network capacity from 480 Gigabytes to 1.9 Terabytes.

"Anritsu Company has been a leader in advancing optical technology," contends Dwane Rose, Anritsu optical engineer. "We continue to be committed to providing test solutions that will help fiber-optic networks meet customer demand. Our participation in a milestone such as this is indicative of our commitment, and we look forward to maintaining our leadership position," he adds. 

The MP1595A analyzer provided the flexibility of service and mappings necessary to validate the subsea span, say Anritsu representatives. The all-in-one measurement device provides full 40G/43G support for all network quality measurements and was used in this case to verify transponder performance.

Huawei's 40G transponders were used to upgrade the existing cable, built in 2000 with a 48-channel, 10G system capacity. The Huawei deployment upgraded the cable to a 48-channel, 40G system, increasing the capacity from 480 Gigabytes to 1.9 Terabytes.

Huawei claims it was the world's first native 40-Gbit/sec deployment over a subsea span.
Huawei's 40G transponder features automatic dispersion compensation, which eliminates the need for DCM modules. Its 40G cards use the same common equipment and also work well with the live 10G traffic, enabling its customers to increase capacity in a cost-effective manner on legacy equipment, say Huawei representatives.

"Anritsu's state-of-the-art test solution provided critical verification that our 40G integrated solution will allow our customer to dramatically and effectively increase the bandwidth capacity offered through their subsea international cable link," notes Wilf Norrlinger, vice president of sales for Huawei. "This milestone is another example of Huawei's ability to form successful industry relationships that deliver industry-leading technologies and the highest levels of customer satisfaction."
