Swisscom upgrades SONATE infrastructure to 100G with Huawei

Swisscom has upgraded its Optical Network for all IP-Transport Services (SONATE) to 100-Gbps DWDM capabilities using technology from Huawei, the two companies say.

Swisscom has upgraded its Optical Network for all IP-Transport Services (SONATE) to 100-Gbps DWDM capabilities using technology from Huawei, the two companies say.

Huawei originally deployed the SONATE infrastructure in 2009. Swisscom created the fiber-optic network, based on 10-Gbps Optical Transport Network (OTN) principles, to deal with rapid traffic growth from fixed and mobile broadband and data center services. The upgrade to 100G increases the SONATE backbone capacity to 8 Tbps to support 1-Gbps per base station and 10 Gbps for fiber to the home (FTTH). Huawei reports the upgraded network has been operating satisfactorily since October of last year.

"The SONATE leads the industry by offering ultra-broadband, OTN to the edge, and multi-service transport. With this super-large 100G pipe, bandwidth-on-demand is no longer a dream," said Jack Wang, president of Huawei's transport product line.

The 100G upgrade leverages such technologies as coherent WDM, hard-decision and soft-decision forward error correction, as well as OTN aggregation and grooming.
