Global fiber backbone provider, TeliaSonera International Carrier (TSIC) and SDN-based transport solution firm, Coriant, last week announced the successful completion of a field trial demonstrating optical transmission speeds of up to 400G per channel. The trial was implemented on TSIC’s existing Coriant® hiT 7300 Multi-Haul Transport Platforms and the 400G flexi-rate trial used the new Coriant CloudWave™ Optics, a versatile suite of software-programmable photonic layer technologies.
According to Coriant, the trial was conducted over multiple spans across a 1,634 kilometer fiber optic route between Paris, Luxembourg, and Frankfurt, using three different software-programmable modulation formats – QPSK, 8QAM, and 16QAM – over the complete distance of 1,634 kilometers each. The trial also featured a variety of line-side transmission speeds (100G, 200G, 300G, 400G) in a mix of capacity and reach application test scenarios.
