Allied Telesis AT-DNC10LC-901 TAA, 10G /LC, MM Network Adapter Card

Product Overview

The Allied Telesis AT-DNC10LC-901 is a TAA-compliant 10 Gigabit PCIe NIC with a fixed LC fiber connector, engineered for servers and workstations requiring high-throughput optical fiber uplinks. This Allied Telesis 10G PCIe NIC LC fiber adapter TAA delivers up to 10Gbps over multimode optical fiber via a PCI Express x4 slot. Powered by an energy-efficient Aquantia (Marvell) AQC10x chipset, the DNC10LC-901 consumes under 2W during normal operation — a critical advantage in high-density server environments. The fixed LC optic design enhances physical security by eliminating the SFP swap vulnerability common in modular NICs, making it a strong choice for government and regulated deployments that require TAA compliance.

Product Description

The AT-DNC10LC-901 belongs to Allied Telesis's DNC10 Series of 10 Gigabit PCI-Express network adapters, designed to meet the bandwidth demands of modern data center applications including large file transfers, virtual machine workloads, and high-density storage traffic. The card installs into a PCIe x4 slot and exposes a single 10GBase-X LC port, ready to connect to multimode fiber infrastructure at full 10Gbps line rate. Unlike the DNC10SP — which accepts pluggable SFP+ optics — the DNC10LC features a permanently integrated LC transceiver, providing both a lower profile and a tamper-resistant optical interface preferred in secured data centers and government networks. TAA compliance makes this adapter eligible for federal procurement under the Trade Agreements Act. The Marvell AQC10x chipset supports Wake-on-LAN (WoL), hardware offload functions, and is validated across a broad set of operating systems and server platforms. With PCIe x4 bus architecture, the DNC10LC-901 can sustain theoretical throughputs of up to 2000 MB/s between the NIC and the host system, keeping the 10GbE link from becoming a bottleneck. The card measures 3.8" x 2.7" x 0.5" and weighs approximately 2.75 oz, fitting standard PCIe slots with a low power draw that minimizes thermal load in dense 1U and 2U server chassis. Available from Creation Networks, this Allied Telesis 10G fiber NIC TAA compliant PCIe adapter is in stock and ships with a US power cord as part of the -901 SKU designation.

Key Features

• PCI Express x4 Interface — Up to 2000 MB/s host bus throughput; compatible with PCIe x4, x8, and x16 slots.
• TAA Compliant — Meets Trade Agreements Act requirements for US federal, state, and regulated-sector procurement.
• Ultra-Low Power: <2W — Energy-efficient Marvell AQC10x chipset reduces heat generation in high-density server deployments.
• Wake-on-LAN (WoL) — Enables remote server power management for data center operations teams.
• Broad OS and Platform Validation — Tested across major server operating systems and hypervisors for assured compatibility.
• Single-Port Design — Dedicated 10Gbps fiber uplink per card; add multiple cards for aggregated bandwidth or redundancy.

Typical Applications

• Data center servers requiring 10G fiber uplinks to top-of-rack switches
• Federal and government IT infrastructure subject to TAA procurement requirements
• Virtualization hosts (VMware, Hyper-V, KVM) needing dedicated 10GbE NIC bandwidth
• Storage servers connecting to 10G fiber SAN or NAS fabric
• High-performance workstations in secure or air-gapped environments
• Network upgrades from 1G copper to 10G fiber without SFP management overhead

Frequently Asked Questions

Q: Does the AT-DNC10LC-901 use a pluggable SFP+ transceiver or a fixed optic?

The DNC10LC-901 uses a fixed, integrated LC optical transceiver. Unlike the DNC10SP model which accepts pluggable SFP+ modules, the DNC10LC has a permanently attached optic. This improves physical security and removes the possibility of an incorrect transceiver being installed.

Q: What fiber type does the AT-DNC10LC-901 support?

The DNC10LC-901 connects via multimode optical fiber (OM3/OM4 recommended for 10GBase-SR distances). Confirm distance requirements against the transceiver's datasheet specifications before deployment.

Q: Is the AT-DNC10LC-901 TAA compliant?

Yes. The AT-DNC10LC-901 is fully TAA (Trade Agreements Act) compliant, manufactured in Singapore, and is eligible for US federal, DoD, and GSA Schedule procurement.

Q: Which PCIe slot sizes does the card fit?

The card uses a PCIe x4 edge connector but is backward compatible with x8 and x16 slots. It will not fit a x1 slot.

Q: Does this NIC support jumbo frames?

Yes, the Marvell AQC10x chipset supports jumbo frames, which is beneficial for iSCSI storage and NFS workloads that benefit from larger MTU sizes.

Q: What operating systems are supported?

Allied Telesis validates DNC10 Series adapters across major operating systems. Refer to the Allied Telesis compatibility matrix for current OS support, which typically includes Windows Server, Linux (RHEL, Ubuntu, SLES), and VMware ESXi.

Q: Where can I purchase the AT-DNC10LC-901?
