Deployment / Use Cases
This SFP module is ideal for extending Gigabit Ethernet networks over fiber optic cabling in enterprise, data center, and service provider environments. Its 10-kilometer reach capability makes it suitable for connecting buildings across campuses or linking network segments in metropolitan area networks.
Common applications include uplink connections between switches, backbone network extensions, and fiber-to-the-desktop implementations where electrical interference or distance limitations make copper cabling impractical. The compatibility with both single-mode and multi-mode fiber provides flexibility for existing infrastructure or new installations.
Data Center Interconnects
Connect switches across data center aisles or between facilities using single-mode fiber for maximum distance with minimal signal loss.
Campus Network Backbones
Extend network segments across multiple buildings while maintaining 1GbE performance and reliability over fiber infrastructure.
Physical Profile
