88100 Delock 2.5G RJ45 PCIe 2.1 x1 Ethernet Network Card

Low-Profile PCIe 2.5GbE NIC for edge and SMB servers with the 88100

The 88100 is a low-profile PCIe 2.1 x1 Ethernet adapter engineered to add a dedicated 2.5GbE RJ45 uplink to compact servers, desktops, and appliance builds where slot real estate and airflow are constrained. Based on the Realtek RTL8125B controller, the design targets stable multi-gigabit connectivity while remaining compatible with standard copper cabling and existing switching, making the 88100 a practical upgrade path from 1GbE without changing the physical network layer.

Architecturally, the PCIe 2.1 x1 host interface of the 88100 aligns well with platforms that reserve higher-lane PCIe slots for storage HBAs, GPUs, or NVMe expansion, while still providing sufficient bandwidth for 2.5GbE traffic. VLAN capability supports segmented networks for management, storage, or tenant isolation, and PXE boot enables standardized bare-metal provisioning workflows. The single-port layout favors deterministic link behavior for dedicated uplinks, out-of-band style management networks, or appliance-facing interfaces where predictable latency and straightforward cabling are preferred.

Why Choose the 88100?

The 88100 delivers a strong density-to-performance ratio by adding 2.5GbE through a low-profile PCIe x1 footprint, enabling incremental network modernization in space-limited nodes. For enterprise deployments, the 88100 supports scalable rollouts across edge sites and SMB racks by keeping integration simple: consistent copper RJ45 connectivity, VLAN-ready segmentation, and PXE-based operational consistency across heterogeneous hosts.

Delock focuses on pragmatic hardware engineering for data-centre-adjacent environments, emphasizing mechanical compatibility, controller stability, and adherence to widely adopted interface standards to reduce deployment risk and streamline lifecycle maintenance.
