CWDM-SFP10G-1590 Use Case
High-Speed Data Center Interconnect with CWDM-SFP10G-1590-CWDM
A multinational enterprise uses the CWDM-SFP10G-1590-CWDM 1590 nm SFP+ 10 Gigabit Ethernet Transceiver Module in a CWDM mux/demux over 40 km of dark fiber to mirror mission-critical databases between two data centers. Outcome: Maximizes existing fiber capacity, lowers CapEx by avoiding new fiber builds, and delivers low-latency, high-throughput disaster recovery and business continuity.
Metro Ethernet Aggregation for Regional ISP
A regional ISP deploys a CWDM ring to aggregate multiple 10 Gbps customer circuits across a 25 km metropolitan network, using the CWDM-SFP10G-1590-CWDM module at 1590 nm on each node. Outcome: Enables scalable 10G service delivery on a single fiber pair, simplifies wavelength management, and reduces operational costs by leveraging existing fiber assets.
Campus Backbone Consolidation and Future-Proof Upgrades
A university campus links five buildings over a single fiber strand by integrating CWDM mux/demux and CWDM-SFP10G-1590-CWDM 1590 nm SFP+ 10 Gigabit Ethernet Transceiver Modules for each 10G segment. Outcome: Achieves significant CapEx and OpEx savings, streamlines cabling infrastructure, and provides a scalable platform for adding up to 18 wavelengths without new fiber deployments.
