XFP-10G-CWDM1491 Use Case
Data Center Interconnect over 80 km SMF with XFP-10G-CWDM1491-10G
Scenario: A cloud service provider links two metro data centers 80 km apart using the XFP-10G-CWDM1491-10G CWDM XFP at 1491 nm on ITU-T G.694.2 C-band. With a native 70 km reach extended to 80 km on low-loss SMF, the module delivers 10 GbE connectivity without optical amplifiers. Benefit: Enables high-bandwidth, low-latency data replication and disaster-recovery services with reduced CAPEX and simplified network operations.
Mobile Backhaul Aggregation for 4G/5G Network Operators
Scenario: A Tier 1 telecom operator aggregates 4G/5G base-station traffic over an 80 km SMF ring using the XFP-10G-CWDM1491-10G in an 8-channel CWDM system. Operating at 1491 nm, each XFP delivers 10 GbE throughput to support CPRI fronthaul and Ethernet backhaul. Benefit: Optimizes existing fiber assets, scales bandwidth for future 5G services, and ensures strict SLA compliance for latency-sensitive mobile applications.
Long-Haul Enterprise Campus Backbone Connectivity
Scenario: A multinational enterprise extends its headquarters network to a remote manufacturing site 80 km away by deploying the XFP-10G-CWDM1491-10G on existing SMF. Co-existing with other C-band channels, this 1491 nm CWDM XFP eliminates the need for costly DWDM upgrades. Benefit: Provides secure 10 GbE links with minimal infrastructure investment, centralizes IT resources, and boosts operational efficiency across distributed sites.
