Keep critical traffic moving across dense optical networks with the Cisco GS7000 EDR TX 2:1 DWDM-28. Designed for service-provider transport architectures, this module fits environments where wavelength discipline and predictable optical performance are essential to carrying revenue-generating traffic. The 2:1 TX design supports transport builds that need efficient use of optical infrastructure without adding unnecessary complexity. In DWDM deployments, that matters: every slot, wavelength, and handoff has a cost. This module is suited to teams building or expanding backbone and metro transport layers that must hold service quality under sustained load. For infrastructure teams, the value is in precision. Cisco GS7000 optical transport components are typically selected where network planning, operational consistency, and long-term platform alignment outweigh commodity pricing. This MPN is a fit for organizations standardizing on Cisco transport hardware and maintaining a disciplined optical roadmap. Use it where transport capacity must be preserved, not improvised. The result is a cleaner optical layer that supports carrier-grade service delivery and gives architects a dependable building block for DWDM-based deployments.
