LR-LINK LREC9030PF 100Mbps PCIe x1 SC Multi-mode Network Card

100Mbps PCIe x1 Fiber NIC

The LR-LINK LREC9030PF is a single-port network interface card built around the Intel 82574 controller. It connects via a PCI Express 1.1 x1 slot and provides a 100Mbps SC multi-mode fiber link. The adapter supports PXE boot and MSI-X interrupts for efficient packet handling. It ships with both low-profile and full-height brackets for flexible installation.

Suited for legacy fiber links; not for gigabit needs

This card fits systems that must maintain existing 100Mbps multi-mode fiber infrastructure or appliances requiring deterministic small-packet performance. It operates reliably from 0°C to 55°C in non-condensing humidity up to 90 percent. Buyers needing 1Gbps or 10Gbps throughput, single-mode reach beyond multi-mode limits, or modern PCIe 2.0 and higher feature sets should select a different adapter.

100Mbps headroom for NFV and appliances

At 100Mbps the controller delivers consistent small-packet rates suitable for network functions virtualisation and lightweight security or medical equipment. The PCIe 1.1 x1 interface supplies 2.5 GT/s bandwidth, which matches the port speed without bottleneck. Multi-mode fiber distance is constrained by the optics; the card itself adds no extra latency. When traffic exceeds 100Mbps sustained, the link saturates and a faster NIC becomes necessary.
