10Gbps BNC Ethernet PCIe Card
Budget: $250 – $750 USD
I need a custom PCI-e network interface card that combines a legacy thin-Ethernet BNC connector with modern 10 Gbps performance. The primary purpose is to let multiple devices—servers, workstations and a few printers—join the same coax segment without migrating our existing cabling.
Scope
• Hardware: complete schematic, multilayer PCB layout, verified BOM and Gerber files.
• Firmware / Logic: MAC-level handling that sustains 10 Gbps over the coax interface, plus EEPROM configuration for plug-and-play recognition in Windows and Linux.
• Driver: a clean, compile-ready driver (preferably based on an open-source 10 GbE stack) that exposes standard settings in the OS network panel.
• Prototype: at least one proof-of-concept board assembled, smoke-tested and ready for field evaluation.
Acceptance criteria
1. Reaches 9.5 Gbps or better in iperf3 tests over 30 m of RG-58 while maintaining <1 % packet loss.
2. Enumerates flawlessly in Windows 10/11 and recent Debian kernels with no unsigned-driver warnings.
3. Thermals stay below 70 °C at ambient 35 °C during a one-hour stress test.
4. Full documentation package (PDF schematics, source files for Altium/KiCad, compiled driver binaries and source).
If you’ve tackled high-speed PCB routing, SerDes, or custom NIC firmware before, let’s talk—I’m ready to move as soon as we agree on the milestones.
