Cisco GS7000 EDR TX 2:1 DWDM-39 | Optical Transport, DWDM — GS7K-TXE21DW-39SA

Keep critical optical services aligned to a precise DWDM plan with the Cisco GS7000 EDR TX 2:1 DWDM-39. Designed for GS7000 transport environments, this transmitter supports wavelength-specific deployment where channel discipline, network consistency, and service continuity matter more than generic optics. The 2:1 transmitter architecture is suited to carrier and service-provider builds that need controlled optical transport behavior across established infrastructure. In dense networks, the value is not simply moving light from point A to point B — it is maintaining predictable placement within the wavelength plan so operations teams can preserve design integrity across upgrades, expansions, and long-haul paths. For organizations standardizing on Cisco optical transport platforms, this module fits into a broader architecture where component selection affects service stability, inventory alignment, and lifecycle planning. The DWDM-39 designation gives procurement and engineering teams a clear fit point for wavelength-specific deployments, reducing ambiguity during spares planning and network turn-up. Choose this model when the network demands a transport component that matches a defined optical strategy rather than a general-purpose alternative. It is built for environments where precision, compatibility, and operational discipline justify the investment.
