Swisscom completes 100G upgrade

Swisscom, a leading global communication service provider has announced the successful upgrade of Swisscom's Optical Network for all IP-Transport Services (SONATE) to 100G, ensuring a superior experience of ultra-broadband services.

SONATE; the pan-Swiss, next generation, WDM-based network ready for all IP, was deployed by Huawei in 2009. To deal with the ever-growing demand for bandwidth, Swisscom developed SONATE, with a long term perspective of having the network architecture ready for the next decade. Based on the end-to-end OTN (optical transport network) spanning from access to backbone, SONATE is expected to provide a future-proof access bandwidth of 1 Gbps per base station and 10 Gbps for FTTH.

This upgrade has seamlessly expanded SONATE's backbone network from 10G to an industry leading 100G with the upgraded network operating stably since October 2012. The company has opted for Huawei's 100G solution uses cutting-edge technologies such as coherent WDM, HD/SD-FEC, and OTN.

Line technologies such as coherent WDM and HD/SD-FEC guarantee the compatibility of 100G signals with the legacy network, allowing for smooth capacity expansion and protecting infrastructure investment. Huawei also help deliver high performance for ultra-long-haul 100G transmission, reducing the need for optical amplifiers and regenerators. 100G OTN implements the switching and grooming of multi-granularity services in a large pipe, assuring the bandwidth efficiency of a 100G system.

"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.
