• fiercetelecom | Posted: 22 Aug 2017, 09:58Ciena and Cisco are reaping the benefits as service providers shift spending from long haul to metro WDM (wave-division multiplexing) network builds.As a result of double-digit year-over-year North America growth in metro WDM, Cignal Al said in its second-quarter 2017 Optical Hardware Report that that Cisco and Ciena grew market share. The research firm said that Ciena’s North American optical equipment revenue increased by 21% year-over-year. Interestingly, the growth in metro WDM spending is creating greater demand for higher speed coherent ports, which are evolving from 200G to speeds as high as 400G later this year. Outside of North America, growth in China is notable as optical revenue rose 13% year-over-year for the first half ...
