SFP-GE40KM Use Case
Long-Distance Data Center Interconnect with SFP-GE40KM
An enterprise operates two data centers 30 km apart and requires a low-latency 1 GbE link over existing single-mode fiber. By deploying the SFP-GE40KM-1-Port GE SFP (40 km reach), the organization achieves secure, high-bandwidth connectivity without intermediate repeaters. Benefit: Delivers reliable, cost-effective data center interconnect with plug-and-play simplicity and carrier-grade performance.
Campus Network Backbone Extension Using 40 km SFP
A university campus must extend its backbone Ethernet network across multiple buildings spanning 15 km over single-mode fiber. The SFP-GE40KM module provides a single-port GE uplink supporting IEEE 802.3z standards, enabling seamless integration into existing switches. Benefit: Enables scalable, interference-free campus connectivity with minimal power draw and straightforward hot-swappable installation.
Rural Cellular Base Station Backhaul with SFP-GE40KM
A mobile operator needs to backhaul 4G/5G traffic from a rural cell site located 35 km from the aggregation node. Installing the SFP-GE40KM-1-Port GE SFP onto the outdoor switch delivers stable 1 GbE transport over long-haul fiber. Benefit: Ensures high-availability, low-maintenance backhaul with efficient power usage and carrier-grade link reliability.
