WSP-Q40GLR4L= Use Case
Hyperscale Cloud Data Center Interconnect
In a hyperscale cloud environment, operators deploy the WSP-Q40GLR4L=-WSP-Q40GLR4L= QSFP 40G ENET LR4 LITE LC 2KM module to connect two data-center pods via single-mode fiber over a 2 km span. This 40 Gbps link delivers ultra-low latency and scalable throughput for seamless VM migration and real-time data replication, while its LR4 Lite optics consume ≤3.5 W per channel for efficient power management.
Low-Latency Financial Trading Backbone
A leading financial institution upgrades its trading network by integrating WSP-Q40GLR4L=-WSP-Q40GLR4L= QSFP 40G ENET LR4 LITE LC 2KM modules to link the exchange floor and data center across a 1.5 km fiber corridor. The 40 Gbps LR4 Lite optics ensure sub-microsecond latency, high reliability, and secure fiber transmission, supporting algorithmic trading and compliance mandates with minimal power overhead.
Enterprise Campus High-Bandwidth Backbone Expansion
A multinational enterprise deploys WSP-Q40GLR4L=-WSP-Q40GLR4L= QSFP 40G ENET LR4 LITE LC 2KM modules to upgrade its campus backbone connecting multiple buildings across a 2 km fiber span. The 40 Gbps capacity supports 4K/8K video conferencing, VR collaboration, and centralized storage access, while the LR4 Lite design reduces OPEX through low power consumption and seamless integration with existing LC fiber infrastructure.
