The QNAP QXG-25G2SF-E810 in depth

Scale your 25GbE network

NAS such as the TS-h2287XU-RP can take the QXG-25G2SF-E810 in a PCIe Gen 4 slot to connect more PCs and workstations at 25GbE. Paired with a 25GbE switch, it builds a fast, scalable network.

Multiply throughput with SMB Multichannel

Adding QXG-25G2SF-E810 ports to a NAS with built-in 25GbE and enabling SMB Multichannel can deliver 50Gb/s or higher to connected clients.

Reliable links with FEC

No FEC gives the lowest latency for short links, while BASE-R FEC (around 80ns) and RS-FEC (around 260ns) support longer distances. Both ends must use the same mode.
