USB 3.0 Fiber Network Adapter

The LR-LINK LREC3210PF-SFP adds a 1000Mbps SFP fiber port to any system with a USB 3.0, 2.0 or 1.1 socket. It uses a Realtek RTL8153 controller and supports IEEE 802.3az for energy-efficient Ethernet. The aluminum shell aids heat dissipation during operation. It suits users who need fiber connectivity without an internal PCIe slot.

Sustained Load Behavior

The adapter maintains gigabit throughput over extended transfers using the USB 3.0 interface. It supports Jumbo Frames and IEEE 802.1Q VLAN tagging for managed network traffic. PXE, DPDK and iSCSI boot or storage protocols function across long sessions. Driver support spans Windows, Linux, FreeBSD and VMware ESXi kernels.

Thermals Noise and Power

The passively cooled aluminum enclosure operates silently without a fan. Power is drawn directly from the USB bus, eliminating the need for an external supply. The IEEE 802.3az standard reduces energy use during low-link utilisation. The compact form factor fits in tight workspaces where active cooling is impractical.

商品問答

How much heat or noise does the LR-LINK LREC3210PF-SFP produce when running continuously?

The adapter has no fan and uses an aluminium shell for passive cooling, so it runs silently; power comes from the USB 3.0 port.

What must I already own to use the SFP port on this adapter?

You need a compatible SFP transceiver module and matching fibre patch cable; the card only provides the SFP cage.

Will the Realtek RTL8153 controller work with my older Linux 2.6.32 kernel or Windows XP machine?

Yes, the driver supports Linux kernel 2.6.32 and later, plus Windows XP through Windows 10 and Server 2008 R2 through 2019 R2.
