Nokia says it partnered with Vodafone Turkey to demonstrate a 1-Tbps per channel coherent transmission over the latter’s live fiber network. The demonstration suggests the ability to increase network capacity to 70 Tbps per fiber.The 1-Tbps was transmitted across 130-GHz bandwidth without errors on Vodafone Turkey’s in-service optical network between data centers. The route benefited from Nokia’s wavelength routing technology, including a non-blocking CDC-F ROADM optical switch architecture and support of C+L band transmission. Equipment used included the 1830 PSI-M (Photonic Service Interconn...
