Questions about this item

Will the LFP441 SFP transceiver operate at 1.25GB with legacy Gigabit switches using 850NM multimode fibre?

Yes, the LFP441 is a 1.25GB 850NM SFP transceiver designed for standard Gigabit Ethernet links over multimode fibre, so it will interoperate with older Gigabit switches that accept SFP modules.

How can I verify the LFP441 is functioning correctly once installed in my switch?

Check the switch port status LEDs for link and activity, then confirm the interface shows a 1.25 Gbps connection with no CRC errors in the switch management console.
