TruePulse is trying to source NT8E01LC and NT8E01LW for the Nortel 2.5gbps modules for the S/DMS TransportNode OC-48.  They may also be known as the Ciena NT8E01LC and Ciena NT8E01LW.

The NT8E01LC module, HECI code SNTXPFY3AA, is an OC-48 long reach 1533 nm ring transmit interface. These circuit packs support OC-3, STS-12, or OC-12 interfaces in all four quadrants of an OC-48 terminal shelf. The NT8E01LC circuit packs are used exclusively for GR-1230 Rings.

The NT8E01LW module, HECI code SNT8H90AAA, is also an OC-48 long reach 1533 nm ring transmit interface. You must order optical connector kits for this circuit packs.  The NT8E01LW circuit pack support OC-3, STS-12, or OC-12 interfaces in all four quadrants of an OC-48 terminal shelf. These circuit packs are to be used in conjunction with OC-48 extended long reach receive interfaces (NT8E02C) or extended long reach high jitter tolerant receive interfaces (NT8E02D). Release 16 and later software has enhanced matched-node capabilities for path defect detection, protection switching, and provisioning. These enhancements are available only if the ADM node is equipped with two NT8E01LW/PW/QW/TW/UW circuit packs. The NT8E01LW supports STS path performance-monitoring counts in the add direction for ring systems

We are also looking for most other Nortel 2.5gbps modules for the S/DMS TransportNode OC-48, including but not limited to the NT8E01BB, NT8E01QW and NT8E01DC.

Please let us know what you have available.
