Compatible SFP Transceiver for Extreme Networks

The 10051-ST is a new SFP transceiver module designed, programmed and tested for Extreme Networks switches and routers. It provides 1 Gbps connectivity over multi-mode fiber with an 850nm wavelength and LC duplex connectors. Network administrators can deploy it for building-level links up to 550m.

Low-Power Hot-Swappable Operation

The transceiver draws minimal power and produces no audible noise because it has no moving parts. Its hot-swappable SFP form factor allows insertion or removal without powering down the host switch, keeping rack equipment running during upgrades or maintenance. The 0.04 lb weight adds negligible load to the chassis.

Steady 1 Gbps Throughput Over Distance

Under sustained load the module maintains the full 1 Gbps transfer rate across the entire 550m multi-mode reach. Digital diagnostics monitoring reports real-time temperature, voltage and optical power so operators can verify link health continuously. The 0.49 x 0.54 x 2.23 inch housing fits standard SFP cages without blocking adjacent ports.

Questions about this item

How do I install the 10051-ST SFP transceiver into an Extreme Networks switch, and what step do people often miss?

Slide the module into an open SFP port until the latch clicks, then remove the dust caps and insert the LC connectors; the step most often missed is confirming the latch is fully engaged before cabling.

What maintenance or replacement will the 10051-ST need over time?

The LC connectors and fiber end-faces should be inspected and cleaned with a lint-free wipe and isopropyl alcohol whenever links are reconnected; the module itself has no user-serviceable parts and is replaced only if DDM alerts show declining optical power.

What is the first limit that appears when the 10051-ST runs continuously at 1 Gbps over multimode fiber?

The 550 m reach limit is reached first; beyond that distance the 850 nm signal attenuates too far for reliable 1000BASE-SX operation.
