Introduction For much of the late 1990s and early 2000s, JDSU (JDS Uniphase Corporation) was the embodiment of the dot-com bubble’s fever dream—and its subsequent nightmare. At its peak in March 2000, the company boasted a market capitalization of over $100 billion , making it one of the most valuable technology companies in North America. Less than three years later, its stock had lost over 99% of its value.
Today, the name “JDSU” lives on only in financial archives and the memories of telecom veterans. But its engineering legacy is everywhere: in the lasers that read barcodes, the instruments that certify fiber to your home, and the components that route data through the cloud. The phoenix that rose from the dot-com ashes didn’t keep the old name—but it kept the technology. Note: Stock prices, market caps, and valuations are historical approximations.
