DWDM-SFP-4532= Use Case
Data Center Interconnect for Scalable 100G Bandwidth
In a multi‐site enterprise requiring real‐time data replication over 80 km, the DWDM-SFP-4532 (1545.32 nm, 100 GHz ITU grid) is integrated into 100G DWDM mux/demux modules. By leveraging existing single-mode fiber and adding a dedicated 1545.32 nm channel, the solution delivers seamless 100 Gbps throughput with ultra-low latency. This approach maximizes fiber utilization, cuts dark-fiber leasing by up to 40 %, and ensures high-availability disaster recovery.
Metro ISP Traffic Aggregation with Dense Wavelength Division Multiplexing
A regional ISP deploys DWDM-SFP-4532 modules in its metro ring to aggregate multiple 10G/40G customer services onto a single fiber span. Operating at 1545.32 nm on the 100 GHz ITU grid, each module provides plug-and-play 100G connectivity without new fiber builds. The result is optimized spectrum efficiency, accelerated service rollout, and a 30 % reduction in operational costs through simplified fiber management.
Low-Latency Financial Trading Link over Dark Fiber
A financial trading firm implements a dedicated 20 km dark-fiber link using DWDM-SFP-4532 transceivers at 1545.32 nm (100 GHz ITU grid) to connect trading engines. The single-wavelength 100 G solution minimizes chromatic dispersion and ensures signal integrity, achieving sub-microsecond latency for market data feeds. This deployment secures a competitive edge by guaranteeing deterministic performance and 99.999 % uptime in mission-critical trading operations.
