Qnap 25 Gbps SFP28 transceiver

The Qnap TRX25GSFP28SR is a plug-in optical transceiver designed for 25 Gigabit Ethernet links. It operates at an 850 nm wavelength using LC duplex connectors and supports the 25GBase-SR standard. The module is built for QNAP network equipment requiring short-range fibre connectivity.

Hot-plug LC module installs in seconds

The transceiver uses a standard SFP28 form factor that slides into a compatible cage without tools. Alignment is straightforward thanks to the keyed LC interface, but the spring-loaded latch can snag on adjacent ports if the cage spacing is tight. Dust caps must be removed before insertion and kept for future moves to avoid contaminating the optical faces.

Ideal for 100 m multimode links in QNAP gear

This unit suits administrators extending 25 GbE connections up to 100 metres over OM3 or OM4 multimode fibre within a rack or between adjacent racks. It is not intended for single-mode distances, for 10 GbE-only switches, or for environments where the SFP28 cage is absent. Buyers needing longer reach or different vendor compatibility should evaluate other transceiver types.

Questions about this item

How do I confirm the TRX25GSFP28SR is operating correctly after installation?

Check the link LED on the connected QNAP switch port; a steady light means the 25 Gbps link at 850 nm is active.

What comes with the TRX25GSFP28SR and what must I purchase separately?

The transceiver module itself is included; you must buy LC duplex multimode fibre patch cables to complete the link.

When should I choose this 850 nm SR version over other SFP28 modules?

Select this module when the run is 100 m or less over multimode fibre; longer distances need a different wavelength.
