The Ciena NTK540BD is a Premium MOTR circuit pack for the Ciena 6500 platform, built with WaveLogic 5 Extreme (WL5e) coherent optics across 6 ports — 1x QSFP-DD and 5x QSFP28. WL5e offers software-programmable line rates from 200 Gb/s to 800 Gb/s per wavelength.
This is Ciena’s higher-capacity coherent generation, aimed at operators pushing per-wavelength throughput on existing 6500 deployments. Available through TelecomLeasing for purchase or lease.
