A system for expanding PCI Express (PCIe) compliant signals over a fiber optic medium with no latency. A standardized fiber optic transceiver is adapted to provide an optimal PCIe expansion over a fiber optic medium. Signal buffers are utilized to translate and fine-tune standardized PCIe traffic to a level of low voltage differential signaling (LVDS) that is comprehensible to a wide range of fiber optic transceivers over a wide range of interface bandwidths. The intended use for such a high-speed LVDS buffer is to strengthen and enable PCIe signals over metal (copper) cable or metal printed circuit board (PCB) traces for large PCBs, such as backplanes, server motherboards, etc. By disposing the PCIe buffer used for metal (copper) cable between the PCIe bus and the fiber optic transceiver, one can achieve the signal conditioning and translating required to allow PCIe signals to pass over the fiber optic medium. |
