Intel's E810-CQDA1 single-port 100GbE adapter draws approximately 20W under full load—a critical detail when you're building out a data centre with dozens or hundreds of these cards. At that power envelope, monitoring becomes more than an operational nicety; it becomes a budgeting reality and a thermal planning requirement. The Intel E810-CQDA1 includes DDM (Digital Diagnostic Monitoring) capability, which means your network operations centre can track optical power levels, temperature, and transceiver health in real time without requiring separate management interfaces or pulling cables to inspect module status. For infrastructure teams scaling 100G fabric across multiple racks, that visibility into per-port power and signal integrity translates directly into faster incident response and fewer truck rolls.

This is a single-port PCIe card, not a multi-port NIC, which means the Intel E810-CQDA1 occupies one full x16 PCIe 4.0 slot but delivers the entire bandwidth to a single QSFP28 interface running at 100Gbps. Network architects and infrastructure engineers select this form factor when they need deterministic, high-priority connectivity to a specific resource—a direct path to a storage array, a dedicated uplink to a spine switch, or an isolated 100G connection to an external HPC cluster. The single-port design eliminates port contention and simplifies traffic engineering compared to multi-port adapters where bandwidth must be shared across several lanes. Passive cooling via a small aluminium heatsink keeps the card silent and eliminates the fan noise that can accumulate in dense server environments, provided ambient temperatures stay within the operating range of 0°C to 55°C, which is standard for most data-centre deployments.

Intel built the E810-CQDA1 with hardware offload for Ethernet, RoCE (RDMA over Converged Ethernet), and iWARP protocols. This means your system can handle remote direct memory access operations without burning CPU cycles—critical for AI labs running distributed model training, financial services firms executing microsecond-sensitive trades, or enterprises deploying SAP HANA clusters where sub-millisecond latency and predictable jitter matter. The card integrates into Intel-based servers and workstations seamlessly; there is no firmware negotiation or driver hunt across multiple vendors. You slot it into an x16 PCIe 4.0 socket, install Intel's network drivers, and the operating system recognizes it as a standard network interface. Height of 111.15 mm and width of 68.6 mm keep the form factor compact enough to fit in single-socket and multi-socket server chassis without requiring custom riser cards or creative cable routing.

The physical QSFP28 port connects directly to your transceiver ecosystem—whether you're running Intel E810 QSFP28 optics, third-party modules, or DAC (direct-attach copper) for short-reach connections within the rack. The E810-CQDA1 itself is the adapter; the transceiver is a separate purchase, which gives you flexibility to match optics to your specific distance requirements and budget. Network teams in the GCC region typically pair these adapters with either 2km LR4 modules for inter-rack fabric or 10km modules for campus-to-campus links, depending on topology. DDM monitoring on the transceiver side feeds back real-time optical metrics—transmitted and received power, temperature offsets, and voltage thresholds—allowing your management platform to alert before a module begins to degrade. In high-density deployments where you're running 48 or more 100G ports across a cluster, that early warning capability prevents cascading failures and keeps your RTO within SLA bounds.

Omnixon Global supplies the Intel E810-CQDA1 and associated optics infrastructure to data-centre operators, AI research labs, and enterprise IT teams across the UAE, Saudi Arabia, Kuwait, and into South Asia and Europe. If you are building or expanding 100G network fabric and need a trusted distributor with stock, technical depth, and local presence, we invite you to submit an RFQ through our portal or contact our sales engineers directly.
