PCI Express Over Fiber Optic Extensions

Overview

PCI Express over fiber optic extension systems allow standard PCI Express cards to operate remotely from the host computer. No additional programming or drivers are required. The operation is transparent, so the add-in cards operate as if they were installed locally in the computer PCIe slots.

  • PCI Express bus is extended up to 500 m
  • Electrical isolation from the host computer
  • Slots support hot-plug for production testing
  • Backplanes operating temperature range from -40° to +85° C
  • Digital monitor and diagnostics via Ethernet port

Performance

The achievable performance of the PCIe cards installed in the extension depends on the card’s PCIe interface implementation, the card drivers, the performance of the chipset in the computer, and the cable length. The achievable performance and technical details of what affects the PCI Express performance can be found in the technical notes:

The system bandwidth is limited by the fiber optic connection. The fiber optic bandwidth is shared between all PCIe cards in the remote backplane.

Custom backplanes and embedded solutions.

The standard extension systems can be modified to meet specific application requirements. For more detailed information, please visit the Embedded Solutions  page.

Optical transceivers and cables

The systems can operate with standard pluggable multi-mode or single-mode QSFP and SFP transceivers, Active Optical Cables (AOC), and Direct Attach Cables (DAC).

Gen 3 extension:

  • 32 or 64 Gb/s cable data rate using 4 or 8 PCIe Gen 3 lanes
  • 1 or 2 QSFPs (1 QSFP per 4 PCIe lanes, 32 Gb/s)
    • Multi-mode or single-mode optical transceivers
      • LC-LC duplex cable (4 lanes optically multiplexed into a single cable)
      • MPO/MPT cable
    • AOC
    • DAC

Gen 2 extension:

  • 5 or 20 Gb/s cable data rate using 1 or 4 PCIe Gen 2 lanes
  • 1 or 4 SFPs (1 SFP per 1 PCIe lane, 5 Gb/s)
  • Multi-mode or single-mode optical transceivers
  • LC-LC duplex cable
