DWDM-SFP-3898= Use Case
High-Capacity Data Center Interconnect with DWDM-SFP-3898 (1538.98 NM, 100 GHz)
Scenario: A cloud service provider needs to link two regional data centers over 50 km of existing dark fiber while scaling from 400 Gbps to multi-terabit capacity. By deploying DWDM-SFP-3898 (1538.98 NM, 100 GHz ITU grid) modules in each edge router, the operator adds a 100 Gbps wavelength on channel 38 without new fiber builds. Benefit: Enables seamless scaling to 9.6 Tbps over a single fiber pair, reduces CAPEX by 60% versus dark-fiber leases, and simplifies network operations through plug-and-play DWDM expansion.
Metro Backbone Bandwidth Consolidation Using DWDM-SFP-3898 (1538.98 NM, 100 GHz)
Scenario: A metropolitan ISP must aggregate dozens of 10 Gbps business circuits into its ring backbone to meet enterprise SLAs. Integrating DWDM-SFP-3898 (1538.98 NM, 100 GHz ITU grid) modules into its DWDM mux/demux allows each 10 Gbps service to ride a dedicated 100 GHz channel on the same fiber. Benefit: Increases spectral efficiency 10×, frees fiber capacity for future services, reduces OPEX by 40% through centralized wavelength management, and accelerates new circuit turn-up from days to hours.
5G Fronthaul & Backhaul Transport with DWDM-SFP-3898 (1538.98 NM, 100 GHz)
Scenario: A mobile operator rolling out 5G C-RAN must aggregate high-bandwidth, low-latency fronthaul traffic from remote radio units to centralized baseband units. By deploying DWDM-SFP-3898 (1538.98 NM, 100 GHz ITU grid) in their aggregation switches, they provision dedicated 100 Gbps wavelengths over existing fiber routes. Benefit: Delivers sub-millisecond latency, ensures 5G-grade throughput, simplifies wavelength planning on a standardized ITU grid, and future-proofs the network for 5G+ services.
