CWDM-SFP-1550= Use Case
Multi-Service Metro Fiber Aggregation with CWDM-SFP-1550
Scenario: A regional ISP must deliver both Gigabit Ethernet and 1G/2G Fibre Channel services across its metro network without laying new dark fiber. By deploying the CWDM-SFP-1550 module at the 1550 nm wavelength, the ISP can multiplex Ethernet and Fibre Channel streams alongside other CWDM channels on a single fiber pair. Benefit: Extends reach up to 80 km, consolidates multiple services over existing infrastructure, reduces capital and operational expenses, and accelerates service roll-out with simplified port management.
Campus SAN Extension via CWDM 1550 nm SFP
Scenario: A large university data center requires a reliable, low-latency 1G/2G Fibre Channel link to replicate mission-critical storage arrays between two campus facilities 40 km apart. Integrating CWDM-SFP-1550 into the Fibre Channel switches enables seamless SAN traffic over the institution’s CWDM network. Benefit: Achieves high-availability storage replication over existing dark fiber, maintains full Fibre Channel performance at 1G/2G speeds, reduces fiber footprint, and ensures data integrity for backup and disaster recovery operations.
Disaster Recovery Link for Enterprise Data Centers
Scenario: An enterprise IT team needs a resilient disaster-recovery connection between two geographically separated data centers, supporting both Gigabit Ethernet and storage replication protocols. Installing CWDM-SFP-1550 modules in switches and storage gateways leverages the 1550 nm channel to carry converged traffic over dark fiber. Benefit: Provides up to 80 km reach with low jitter and minimal latency, converges LAN and SAN traffic on a single wavelength, optimizes fiber assets, and meets stringent RPO/RTO objectives for critical applications.
