Single-port M.2 Gigabit adapter

The LR-LINK LRES2212PF-SFP adds one 1000Mbps SFP fibre port to any system with an M.2 A+E key slot. It targets industrial PCs, single-board computers and compact appliances that lack a full-size PCIe slot but need wired Ethernet. The Intel I210 controller provides four transmit and four receive queues per port. Low-power operation suits space-constrained deployments.

IEEE 802.3az link constraints

The card negotiates at 1000Mbps full-duplex over the SFP cage; it cannot exceed that rate or fall back to 10/100 copper without a compatible module. Cable reach and media type depend entirely on the SFP transceiver inserted, so distance limits are not fixed by the adapter itself. Operating temperature is rated 0°C to 55°C with 0–90 % non-condensing humidity.

One fibre port headroom

A single 1000Mbps fibre link handles typical industrial camera streams, PLC traffic and moderate storage replication without saturation. Workloads that demand multiple concurrent gigabit flows or 10 Gbps uplinks will exceed the available bandwidth. The M.2 2230 form factor also fits 2242 and 2260 key slots, but the controller remains limited to one port.

Questions about this item

Does the LRES2212PF-SFP support different M.2 slot lengths?

The card uses an M.2 A+E key 2230 interface and is compatible with 2242 and 2260 length slots.

What real-world throughput can I expect from the 1000Mbps SFP port?

The Intel I210 controller delivers full gigabit wire speed with four transmit and four receive queues for efficient DMA handling.

Which IEEE standard governs the SFP link and what does it cap?

The adapter follows IEEE 802.3az for 1000BASE-X fibre, capping the link at 1000Mbps full duplex.
