Technology Directions in Fiber-Optic CommunicationDecember 12, 2007
Chris Cole, Finisar Corporation
The lecture will first summarize standard communication system limitations, including symbol rate, channel capacity, modulation format, and distortion. Several communication system examples will be described including voice-band datacom, computer datacom, and optical datacom. Several examples of today's fiber-optic communication modules will be described. With this background, new technology directions in fiber-optic communication will be presented. These are multiple channels, complex modulation, distortion compensation, and single channel full-duplex.
Chris Cole is a director at Finisar Corp., Sunnyvale, Calif. He received a B.S. in aeronautics and astronautics, and B.S. and M.S. in electrical engineering from the Massachusetts Institute of Technology. At Hughes Aircraft Co. (now Boeing SDC,) and then M.I.T. Lincoln Laboratory, Chris contributed to multiple imaging and communication satellite programs. Later, he consulted on telecom ICs for Texas Instruments' DSP Group and Silicon Systems Inc. (now Teridian.) At Acuson Corp. (now Siemens Ultrasound,) Chris was one of the architects of the Sequoia coherent imaging ultrasound platform, where he was also director of hardware and software development groups. As a principal consultant with the Parallax Group, he carried out signal processing analysis and product definition for several imaging and communication systems. Chris is now managing the development of 40-Gb/s and 100-Gb/s LAN and WAN optical transceivers at Finisar (which acquired his previous company, Big Bear Networks.) He is a Senior Member of the IEEE.
