The Ciena NTK665AB (HECI/CLEI: WOCUA77KAA) is a PKT/OTN XC I/F 100G circuit pack for the Ciena 6500 Packet-Optical Platform. Specifically, it’s a 100G interface card for the 6500 T-Series, which uses a central cross-connect fabric to switch packet and OTN traffic. As a result, it brings 100G services onto the shelf’s switching fabric.

100G Packet and OTN Switching

In addition, the card connects 100G traffic to the T-Series’ centralized packet and OTN cross-connect. Consequently, operators can groom, switch, and protect services across many interface cards instead of wiring fixed point-to-point paths. Moreover, this fabric-based design scales to terabit switching capacity on a single shelf.

Built for the 6500 T-Series

Ciena designed the T-Series for large aggregation and core sites that need high-capacity packet and OTN switching. Therefore, the NTK665AB suits carrier backbones, metro core nodes, and data center interconnect hubs. For more on the platform, see Ciena’s 6500 Packet-Optical Platform overview.

NTK665AB vs. NTK665AA

Both are PKT/OTN XC I/F 100G circuit packs. However, the NTK665AB is the later revision, and each carries its own CLEI (WOCUA77KAA for the AB and WOCUA2XKAA for the AA). For this reason, match the exact part number and software release when ordering spares. By comparison, the Ciena NTK669AJ adds a built-in 100G coherent DWDM line.

Key Features

• First, it provides a 100G packet/OTN interface for the 6500 T-Series.
• Second, it connects to the shelf’s central cross-connect fabric.
• Additionally, it supports packet and OTN grooming and switching.
• Furthermore, it enables service protection across the fabric.
• Moreover, it scales with terabit-class T-Series shelves.
• Finally, it serves as a critical spare for deployed T-Series networks.

Why Lease from Telecom Leasing?

• First, you add 100G switched capacity without a large capital outlay.
• Second, we test every unit so it’s ready to deploy.
• In addition, flexible terms cover spares, upgrades, and project builds.
• Finally, you get fast quotes and quick shipping.

Best of all, Telecom Leasing offers the NTK665AB for lease or purchase, so you can expand 6500 T-Series capacity at a fraction of new cost.
