Ciena 6500 WL5E MOTR SUBM REGEN KIT – NTK540BE-NL

Ciena 6500 WL5E MOTR Submarine Regen Kit (NTK540BE is a high-capacity optical transport solution built for long-haul subsea networks. At its core is the WaveLogic 5 Extreme (WL5e) MOTR circuit pack, a programmable 6-port muxponder that optimizes bandwidth across extreme distances. The hardware integrates a versatile mix of client-side interfaces, featuring one QSFP-DD port and five QSFP28 ports, to efficiently aggregate diverse client services. On the line side, it utilizes a single-carrier coherent DWDM line interface capable of scaling capacity from 200 Gb/s up to 800 Gb/s per wavelength.

What defines this specific “Regen Kit” is the inclusion of built-in software licenses for \(ODU_{CN}\) regeneration. This allows the module to act as a high-performance regeneration point, clean up degraded optical signals, and extend network reach without requiring separate transponders. Depending on the exact licensing tier, these kits can extend transport distances from 3,500 km up to 14,000 km. By combining software-defined line rates, advanced forward error correction (FEC), and robust hardware, the NTK540BE kit maximizes spectral efficiency, reduces total cost of ownership, and ensures reliable, ultra-high-speed data delivery across transoceanic routes.
