Avago Technologies Ltd and PLX Technology Inc. are teaming up on the use of optics in an attempt to widen PCI Express' (PCIe) scope from within the box to a cabled box-to-box solution.

According to PLX, a supplier of high-speed I/O connectivity solutions, and Avago, a supplier of analog interface components, this higher-performance alternative paves the road for next-generation data center applications where lower latency, lower cost, extended cabling distances and I/O conversion minimization create simpler architectures for cleaner PCIe end-to-end environments.

The demonstration from the collaboration features PLX PEX8748 PCIe Gen3 (8Gbps per lane) switches, along with Avago high-density MiniPOD parallel fiber optic modules, both of which are set up in an x8 configuration, showcasing external box-to-box high-performance connectivity at 64Gbps, the companies said.

The companies said through a statement that PCI Express as an interconnect for data centers using parallel optics will enable a wide variety of applications including storage, servers and GPU clustering.

"With PCI Express now native virtually everywhere, including Intel platforms and SSD storage modules, the market is hungry for reliable and harmonious solutions," said Reggie Conley, senior director of hardware applications at PLX. "As the market drives down the cost of optical solutions, today's cumbersome and costly conversion of PCI Express to Ethernet or InfiniBand will be replaced by clean system architectures enjoying the fruits of PCIe and optical connectivity's premium performance."
