TruePulse would like to buy surplus NTK538DR and NTK538FR for the Ciena 6500 packet-optical platform.

The NTK538DR, HECI code WOWUBE8, is a Ciena 6500 WLAi MOTR 4x QSFP28 circuit pack.  It is an optical transponder and service channel interface that enables a scalable and programmable infrastructure. An MOTR, or Muxponder Optical TRansponder, provides client ports to a DWDM Line.  The NTK538DR supports four 100G QSFP28 clients and a programmable 400G coherent line interface.  Physically, the circuit board is a single-slot module. The pluggable QSFP28 client ports support high-speed OTU4 or 100GE connections.

The NTK538FR, is a Ciena 6500 WLAi FOTR 34-port (4x QSFP28/ 14x SFP+/ 16x SFP28/) circuit pack.  It is a highly dense optical transponder and service channel interfaces that enable a programmable infrastructure. The NTK538FR supports up to thirty-four clients (four QSFP28/QSFP+, fourteen SFP+, and sixteen SFP28/SFP+ pluggable modules) and a programmable 400G coherent line interface.  Physically, the circuit board is a double-slot module.

In addition to the NTK538DR and NTK538FR, TruePulse is searching for multiple other circuit packs for the Ciena 6500.  We are also interested in Ciena circuit packs to other platforms, including the CoreStream, the Optera Connect DX, the Optera Metro 5200 and the S/DMS TransportNode OC-48 NE.
