Nortel NTK557AA: 80G STS-1/VC-3 cross-connect card for the Nortel OPTera Metro 5100/5200 platform.

The Nortel NTK557AA is an 80G cross-connect circuit pack with STS-1/VC-3 granularity for the Nortel OPTera Metro 5100/5200 (OM5100/OM5200) platform, part of the documented NTK5-prefixed OM5100/5200 circuit-pack family. It provides the shelf’s non-blocking electrical cross-connect fabric at STS-1/VC-3 granularity, switching traffic between the platform’s tributary and aggregate line cards within an 80Gbps switching capacity. OPTera Metro 5100/5200 systems remain in service across a number of established metro SDH/SONET transport networks, and genuine cross-connect cards such as this one are a routine requirement for restoring a shelf to full working order after a card failure, since the cross-connect is central to every path through the shelf. Specifiers should confirm the exact shelf variant and software release against their specific OM5100/5200 configuration before ordering. Tech-Star (UK-based, shipped worldwide) stocks Nortel OPTera Metro cross-connect cards to support ongoing network maintenance. Please contact our sales team to confirm exact compatibility and for current stock and pricing.
