CD laser optical data links for workstations and midrange computers

Abstract

The Optical Link Card (OLC) is a high speed fiber optic data link developed for low cost computer interconnect applications Several versions of thls OLC family are now in volume production They incorporate a short-wavelength, CO-type laser source, high-density surface mount (SMT) packaging. and a novel technique to comply with worldwide laser safety regulations The current cards operating at 220 Mbls and 266 Mbls over 2 km of multimode optical fiber, provide compalibility with the emerging ANSI standard called Fiber Channel Future extensions. especially lo higher data rates, are being developed to meet the computer user's growing demand for higher bandwidth networking solutions

Advances in local area optical data communication systems

“…That meant modal noise was not an issue. In addition, they showed that CD lasers of the self-relaxationoscillation type could be modulated at gigabit per second data rates [70,71].…”
