A regional service provider deploys CWDM-SFP-1590 (1590 nm CWDM SFP GB ENET & 1G/2G FC RED) to deliver 1 GbE internet and 1/2 Gb FC storage services over a single dark‐fiber pair between central office and enterprise sites. By leveraging the 1590 nm wavelength, the provider doubles fiber capacity and avoids costly new builds. Outcome: Up to 40 km reach, guaranteed SLAs for data and storage traffic, and 30% lower OPEX through wavelength‐division multiplexing.
A financial institution uses CWDM-SFP-1590 in its DWDM/CWDM mux to establish a dedicated 1 GbE link alongside a 1/2 Gbps Fibre Channel tunnel between production and disaster-recovery sites. The standardized SFP form-factor and 1590 nm wavelength enable seamless integration into existing CWDM frames. Benefit: Continuous zero‐downtime replication, sub-5 ms latency, and reduced capital expenditure by reusing metro dark fiber.
A large campus network integrates CWDM-SFP-1590 modules into its edge switches and SAN directors to carry Gigabit Ethernet and Fibre Channel over a single CWDM fiber ring. This converged infrastructure approach simplifies inventory, slashes fiber counts by 50%, and accelerates provisioning of new buildings. Result: Streamlined operations, future-proof scalability up to 8 CWDM channels, and a unified management plane for both Ethernet and storage traffic.
