StarTech.com SFP transceiver

If you manage a campus, office building or data centre, you know how frustrating it can be to run short-range copper cables that limit bandwidth and distance. You need a solution that plugs into existing Cisco Meraki switches, extends reach, and stays reliable. This SFP transceiver matches Meraki hardware, eliminates bottlenecks and simplifies network expansion.

Benefits of StarTech.com SFP transceiver

• Easy installation: Hot-swap design means no network downtime.
• Long reach: 550 m capability reduces the need for extra equipment.
• Low power: Under 1.2 W keeps operating costs down.
• Real-time monitoring: DDM lets you track health and prevent failures.
• Lifetime warranty: Peace of mind with free technical support forever.

Usages of a 1.25 Gbps SFP transceiver

Ideal for connecting Meraki switches to remote floor switches, linking server rooms across a building, or extending campus networks where fibre runs are required but budget constraints limit the use of higher-cost optics. It works perfectly in enterprise, education and small-business environments that rely on 1000BASE-SX multimode fibre.
