The Gigabit Link Interface Board (GLIB) is a mid-size double-width Advanced Mezzanine Card (AMC) conceived to serve as an evaluation platform and an easy entry point for users of high speed optical links in high energy physics experiments. It can process data to/from four SFP+ transceiver modules, each operating at bi-directional data rates of up to 6.5Gbps since it is based on a Virtex-6 FPGA with twenty 6.5Gbps transceivers. Its I/O capability can be further enhanced with two FPGA Mezzanine Cards. The GLIB also carries a GbE PHY as well as an Ethernet plug in order to interface to a PC through a standard Ethernet cable, while in bench-top operation.
