Ciena NTK528AA Optical Transponder XFP Line I

Ciena NTK528AA Optical Transponder XFP Line I is a 10 Gbps XFP‑form factor transponder designed for the Ciena 6500 Packet‑Optical Platform, delivering a dedicated OTSC optical transponder interface for OTN‑transparent networks. This single‑channel module plugs into the 6500 shelf and provides a 1x10G optical path, enabling the transport of a 10 Gbps client signal through the platform’s optical transport layer while preserving OTU framing within the OTN envelope. The NTK528AA is an NTK‑series transponder option within the OME 6500 family, used to extend reach across optical networks by supplying a standard XFP interface for line‑side transport. Typical deployment scenarios include carrying 10G client services over an optical transport network with OTN transparency, where signal integrity and alignment with the 6500’s line‑card ecosystem are essential. Key identifiers for this part are the 10 Gbps data rate, XFP form factor, and its role as an optical transponder interface within the 6500 platform lineup, with the NTK528AA designation specifically pointing to this 10G OTSC transponder variant used on the Line I configuration.
