The Ciena NTK538FR (HECI/CLEI: WOWUBFMEAA) is a WaveLogic Ai (WLAi) FOTR circuit pack for the Ciena 6500 Packet-Optical Platform (OME 6500). Specifically, it pairs Ciena’s WaveLogic Ai coherent modem with 34 client ports and, as a result, aggregates a wide mix of services onto one programmable DWDM wavelength.

In addition, its client side combines 4x QSFP28, 16x SFP28, and 14x SFP+ ports. Consequently, operators can carry 100GbE, 25GbE, and 10GbE services on a single card, which saves shelf slots and simplifies migration from 10G to 100G and beyond. Moreover, WaveLogic Ai’s programmable line rate lets capacity be tuned to the span, so the card maximizes throughput on shorter metro links while still reaching across long-haul routes.

Notably, line capacity and reach are enabled through Ciena software licensing; for example, the NTZF53CN terrestrial base kit pairs the NTK538FR with a license for 2x100G clients and reach up to 1,000 km. For these reasons, the NTK538FR is a strong fit for data center interconnect, metro and regional aggregation, and 6500 capacity upgrades. Best of all, Telecom Leasing offers it for lease or purchase, giving operators a cost-effective path to high-density coherent transport.
