The Ciena NTK667AB (HECI/CLEI: WOTRDW1FAA) is a PKT/OTN I/F 100G 10x XFP circuit pack for the Ciena 6500 Packet-Optical Platform. Specifically, it provides ten XFP client ports that connect to the 6500’s packet and OTN switching fabric. As a result, operators can switch and groom up to 100G of 10G services on a single card.

Ten XFP Ports for 10G Services

In addition, each of the ten XFP ports supports multiple 10G rates: 10GBASE-R (10GE LAN), 10GBASE-W, OTU2, and OTU2e. Consequently, one card handles Ethernet and OTN client services side by side. Moreover, Ciena’s documentation lists RS8 FEC support on the OTU2 and OTU2e rates.

Packet and OTN Switching

Furthermore, the card hands traffic to the shelf’s central packet and OTN switching fabric rather than a fixed transponder line. Therefore, operators can groom, switch, and protect 10G services across many interface cards and route them onto 100G line interfaces anywhere in the shelf.

NTK667AB vs. NTK667AA

Both are PKT/OTN I/F 100G 10x XFP circuit packs, and Ciena documents them together with the same supported rates. However, the AB is the later version, so match the exact part number and software release when ordering spares. For 100G client interfaces on the same switching fabric, see the Ciena NTK665AB PKT/OTN XC I/F 100G. For more on the platform, see Ciena’s 6500 Packet-Optical Platform overview.
