PCI Express-to-Fiber Cable Adapter
The PCIe x4 Fiber Cable Adapter converts PCIe signals from electrical to fiber optics, then back to electrical again. On the rear panel of the module, OSS-PCIe-FCA-x4 mates with the standard PCIe x4 cable. On the front panel, it mates with a standard MTP/MPO ribbon fiber connector containing 12 fiber optic links (only 8 of the 12 fibers are used).
OSS-PCIe-FCA-x4
Product Features
- Supports PCI Express x4 links
- Utilizes the POP4 optical transceiver for cable lengths up to 300 meters
- Automatic Host/Target mode detection
- Module supplies PCIe reference clock (no SSC support)
- Other PCIe cable sideband signals connected via CAT5 cable

Typical Configurations
Networked Application
Where multiple computers are networked through the SuperSwitch products, one end of the FCA connects to the host PC through a PCIe cable to a PCIe host cable adapter installed in the host PC’s PCI Express slot. An optical fiber cable then connects the other end of the FCA to another FCA cabled to another PC or the 1U PCIe switch. The following illustration shows the FCA connected to multiple computers using SuperSwitch.
IO Expansion Application
Where a host computer is cabled to downstream expansion or IO end points, the FCA connects to the host PC through a PCIe cable to a PCIe host cable adapter installed in the host PC’s PCIe slot. An optical fiber cable then connects the other end of the FCA to another FCA cabled to a downstream board installed in an expansion system or IO end point. The following illustration shows the FCA connected to an IO end point.
