We have received several NTCA26CA modules for the Nortel Optera Connect DX platform. These NTCA26CA have HECI code WMIUU40.
The NTCA26CA DX140 switch module supports 140 Gb/s module. This compares to the NTCA26BA or DX100, and NTCA26AA or DX65 module.
Although Nortel went bankrupt in 2009 http://www.truepulse.com/nortel-reaches-bankruptcy-settlement/ with their optical assets being sold to Ciena http://www.ciena.com/, many customers are still running legacy Nortel OC-192 systems. TruePulse still carries inventory of many Nortel OC-192 modules, and is actively purchasing select wavelengths.
Some of the modules currently in stock include the AM2 Transmit/Receive modules: NTCA06MP, NTCA06VP, NTCA06EP, NTCA06KP, NTCA06FP, NTCA06XP, NTCA06GP, NTCA06LP, NTCA06NP, NTCA06UP, NTCA06PP, NTCA06PP, NTCA06JP, NTCA06QP, NTCA06WP, NTCA06RP and NTCA06YP.
Please let us know if you are looking to buy or sell NTCA26CA or other Nortel Optera modules.
