Deployment / Use Cases
This 1000BASE-EX SFP module is ideal for connecting network equipment across extended distances where copper Ethernet limitations apply. The 40km reach capability makes it suitable for campus networks, metropolitan area connections, and data center inter-building links where single-mode fiber infrastructure is already deployed.
Common deployment scenarios include connecting Cisco switches in distributed enterprise environments, extending network segments between buildings, and establishing reliable backbone connections for service provider networks. The hot-swappable design allows for maintenance and upgrades without network downtime, while the MSA compliance ensures broad compatibility beyond Cisco-specific deployments.
Campus Network Expansion
Connect switches across multiple buildings within educational, corporate, or healthcare campuses using existing single-mode fiber runs. The 40km distance support accommodates most campus-scale deployments without requiring intermediate equipment.
Data Center Interconnects
Establish reliable 1GbE connections between data center facilities or within large data center complexes. The single-mode fiber compatibility and DDM support provide the monitoring capabilities needed for critical infrastructure links.
Physical Profile
The compact SFP form factor measures just 0.50" × 0.50" × 2.20" (12.70 mm × 12.70 mm × 55.88 mm), making it suitable for high-density switch installations where space optimization is critical. The lightweight 0.70 oz (19.84 g) construction minimizes mechanical stress on SFP cages during installation and removal cycles.
