QNAP TRX-25GSFP28-SR 25GbE SFP28 Short-Range Optical Transceiver
Overview
The TRX-25GSFP28-SR is a 25GbE SFP28 short-reach optical transceiver designed for use with compatible QNAP network switches and high-density NAS enclosures that support SFP28 uplink slots. Deploying 25GbE optical links between storage nodes, top-of-rack switches, or NAS-to-server backbones requires transceivers validated against the host device firmware — using uncertified third-party modules risks compatibility flags or outright rejection at link negotiation. The TRX-25GSFP28-SR is sourced as a genuine QNAP component, eliminating that variable in your deployment.
Compatibility
Designed for QNAP devices equipped with SFP28 (25GbE) ports. Compatible product families include QNAP QSW-series managed switches with SFP28 uplink ports and QNAP NAS models featuring 25GbE SFP28 expansion slots (such as select TVS-h and TES series units with compatible PCIe network cards). Verify your specific QNAP device's transceiver compatibility list before ordering — SFP28 form factor does not guarantee firmware-level acceptance across all host platforms. LC-LC fiber cabling required; this is an SR (short-range) module suited for intra-rack or short inter-rack runs.
