Finisar's 40G Quadwire AOC is a 40 Gb/s parallel active optical cable for storage, data, and high-performance computing interconnectivity. It transmits error-free parallel 4x10 Gb/s data over multimode fiber (MMF) ribbon cables. Based on Finisar's vertically integrated VCSEL array technology and designed with QSFP MSA-compliant high-density connectors, this cable is compact, lightweight, and low power. The Quadwire AOC is ideally suited for datacenter reaches up to 100m for InfiniBand QDR, 40G Ethernet, and other datacom and high-performance computing applications. The FCCx410QD3Cxx features Finisar's Connectivity Diagnostics suite of tools, which helps data center technicians quickly and intuitively find specific modules in a sea of sockets using a visual indicator. LynkFind™ allows an operator to light up the pull-tab of the module at the far-end of a link by pressing the pull-tab of the near-end module. LynkGuardian™ lights up the modules at both ends of a link when either module experiences a fault. Together, these patented tools bring the intelligence normally available through data center monitoring software to a simple and intuitive visual indicator. The benefits to the data center operator enable faster installation and maintenance, easier troubleshooting, and simplified operations.
