Cisco NCS 5700 QSFP-DD MPA Spare | 10GBase-DWDM, Optical Network

Keep critical optical links available with a spare module designed for Cisco NCS 5700 service-provider environments. This QSFP-DD MPA spare supports 10GBase-DWDM operation over single-mode fiber, giving you 10 Gbit/s throughput and reach up to 40 km on a single LC connection. It is a practical fit for long-distance aggregation, metro transport, and data networking paths where predictable optical performance matters more than commodity pricing. For teams managing distributed infrastructure, the value is in preserving service continuity. A verified spare reduces recovery time when a transceiver fails, while DWDM support helps maximize fiber plant efficiency without changing the physical route. The module’s optical fiber compatibility and single-port design keep deployment straightforward in environments that already depend on disciplined optics planning. Choose this spare when the cost of a link outage exceeds the cost of keeping a qualified replacement on hand. It is built for operators who need a known-good part for fast restoration, not a generic substitute.
