C&N TXA309 10Gb SFP+ Adapter

The C&N TXA309 adds a single open SFP+ port to a server or workstation through a PCI Express x4 slot. It uses the Intel 82599EN controller to deliver 10 Gbps Ethernet connectivity for high-speed local data transfer and stable Internet access. The low-profile bracket fits standard and compact chassis alike.

Upgrade from 1 GbE copper links

Replacing a gigabit NIC with this card removes the 1 Gbps bottleneck on backbone links, backup targets and storage clusters. The jump is worth it when sustained throughput above one gigabit is needed for virtualisation traffic, large file moves or multi-user NAS access. The SFP+ cage accepts the transceiver or DAC that matches your fibre plant.

Sustained 10 Gbps line-rate operation

The Intel 82599EN handles full-duplex 10 Gbps without throttling under continuous load. Hardware flow control (IEEE 802.3x), VLAN tagging (IEEE 802.1Q) and link aggregation (IEEE 802.3ad) keep frames ordered during prolonged bursts. Supported IEEE 1588 and 802.1AS precision time protocols maintain sync for latency-sensitive workloads.

Questions about this item

What PCIe slot width does the TXA309 require?

The TXA309 uses a PCI Express x4 bus and fits x4, x8 or x16 slots.

How is the Intel 82599EN controller initialised during setup?

Install the card, attach an SFP+ module or DAC, then load the Intel driver for your OS; the port will not link without a transceiver.

Which transceiver types can be used later with the open SFP+ port?

The port accepts 10GBase-SR, LR, ER, ZR and LRM modules, plus direct-attach or active optical cables.
