DWDM-SFP-3739= Use Case
High-Capacity Data Center Interconnect with DWDM-SFP-3739
In a multi-site enterprise environment, IT architects deploy DWDM-SFP-3739 (1537.40 nm) build-to-order transceivers to aggregate 100 GbE links over a single dark-fiber pair. This DWDM SFP module ensures ultra-low latency, maximized fiber utilization and predictable channel management, delivering up to 96 wavelengths per fiber for scalable, cost-efficient Data Center Interconnect (DCI) with enterprise-grade reliability.
Metro Ethernet Network Densification for Service Providers
Regional telecom operators upgrade ring and mesh topologies by inserting DWDM-SFP-3739 (1537.40 nm) modules into existing line cards to add a dedicated 100 Gbps wavelength without new fiber builds. The build-to-order design delivers precise channel spacing and ITU-compliant pass-through performance, enabling rapid service turn-up, reduced CAPEX/OPEX and future-proof expansion for high-density metro Ethernet services.
5G Mobile Fronthaul/Backhaul Over DWDM Fiber Links
Mobile network operators deploying centralized RAN (C-RAN) leverage DWDM-SFP-3739 (1537.40 nm) to multiplex multiple eNodeB/ gNodeB links on a single fiber, reducing site footprint and power consumption. This DWDM SFP module’s build-to-order wavelength accuracy and ITU grid compliance guarantee sub-microsecond latency, carrier-grade uptime and seamless scalability for 5G fronthaul/backhaul transport.
