This fiberoptic data link can be thought of as a general purpose, optically isolated, point-to-point port through which information can be transmitted at relatively high data rates. A commercially available transmitter/receiver chipset, manufactured by Advanced Micro Devices (AMD) and called TAXI, is used. The transmitter chip encodes up to 10 parallel data bits, serializes them, and outputs the result at 125 Mbits/sec. This serial data stream is then fed to an optical transmitter which passes the data through a fiberoptic cable to a remote optical receiver. This optical receiver then converts the optical signal into an electrical bit stream that is applied to the input of the AMD receiver chip. The receiver chip decodes the data, performs a serial-to-parallel conversion, and then outputs the data in parallel along with a strobe which occurs at a data valid point. The result of this operation is the transfer of parallel data over a serial optical link that is basically transparent to the user.
