TruePulse would like to purchase NTK538BK and NTK538UJ, optical transponders for the Ciena 6500 product line.  You may also know them as Nortel OM6500 NTK538BK and Nortel OM6500 NTK538UJ.

NTK538BK, HECI code WOTRDNR, is a 100G MOTR WL3N ENH C-Band 10X SFP+ Circuit Pack, or a mux optical transponder for the Ciena 6500.

NTK538UJ, HECI code WOWUBAP, is a 100G OTR WL3E PREM C-Band LR4 Multirate Circuit Pack, or an optical transponder for the Ciena 6500.

The Ciena 6500 offers SONET/SDH applications important functionality.  Existing network service provider infrastructure is heavily based on TDM transport, and NSPs will continue to require transport of TDM services during their evolution to a data-centric network. The 6500 provides all the expected SONET functions with excellent densities and flexibility. High density DS1/E1, DS3/E3, EC-1/STS-1 copper interfaces, modular and per port selectable OC-3/STM-1, STM-1e, OC-12/STM-4, OC-48/STM-16 with optional DWDM, and OC-192/STM-64 and OC-768/STM-256 interfaces with optional DWDM provide carriers with a robust service offering and the peace of mind that comes with service forecast tolerance. Per-port selectable protection schemes offer optimum shelf and capital expenditure efficiency and flexibility in the restoration schemes as well as service level agreements being offered.  Unrestricted bandwidth management capabilities on the cross connect result in a more efficient use of the optical network and prevent premature overlays of equipment that result from limited grooming capabilities.

TruePulse buys and sells surplus and decommissioned Telecommunications equipment.  In addition to the Ciena NTK538BK and NTK538UJ, we are searching for other Ciena 6500 modules as well.  Beyond that, we are looking for other modules for other Ciena platforms, such as the CNX-5 and the CoreStream LH.  Please tell us about any surplus central office telecommunications equipment that you have.
