Cisco ESS-TXP-SIA5 Coherent DWDM Interface SIA 60-120 Months | Licensing — ESS-TXP-SIA5

Lock in long-term support coverage for Cisco coherent DWDM interfaces with a 60-120 month SIA. This service agreement is designed for teams that need predictable lifecycle support across optical transport environments where uptime, planning discipline, and vendor accountability matter. A multi-year SIA can reduce renewal churn and make it easier to map support costs to the expected life of the deployment. For procurement and architecture teams, that means fewer short-term decisions and a clearer path for maintaining service continuity across critical DWDM infrastructure. This offering is especially relevant when the network design depends on coherent optics and the support model must stay aligned with the installed base over many years. It gives organizations a structured way to secure coverage without revisiting the same support decision every budget cycle. Ideal For Securing long-term support for coherent DWDM deployments Planning optical network budgets across multiple fiscal years Reducing renewal frequency for enterprise transport infrastructure Maintaining service coverage for installed Cisco optical interfaces Why This Product 1 Longer support horizon than standard annual coverage 2 Built for coherent DWDM interface environments 3 Improves budget predictability across multi-year planning 4 Keeps support tied to Cisco optical infrastructure
