From fiber to AI: A laser giant’s rebirth

Asianometry doesn't just recount the history of a failed telecom giant; they frame the story of JDS Unifase as a cautionary tale of how technological necessity can be hijacked by financial insanity, only to be redeemed by a completely different technological revolution. The author's most striking claim is that the same company which once paid $41 billion for a firm with $187 million in revenue is now the silent backbone of the artificial intelligence boom, proving that capital destruction does not always mean technological obsolescence.

The Architecture of a Bubble

The narrative begins not with the crash, but with the quiet ingenuity that preceded it. Asianometry writes, "Prior to the 1990s, Nortell's fiber optic business lost money for 10 years straight," setting the stage for the founders of JDS Optical to step in. The author effectively highlights how the company's early success was built on dense wavelength division multiplexing (DWDM), a technology that allowed single-mode fiber to carry multiple signals simultaneously by encoding them in different light wavelengths. This technical detail is crucial; it explains why the company was so valuable before the bubble burst. The ability to upgrade capacity without laying new cable was the holy grail for telecoms.

From fiber to AI: A laser giant’s rebirth

As the internet demand surged, the author notes the shift from linear growth to exponential mania. "The entire telecommunications industry is growing like a fast spinning vortex driven by the need for more bandwidth at lower costs and greater flexibility," explains co-founder Joseph Strauss in a 1998 interview cited by Asianometry. This quote captures the zeitgeist perfectly, but the commentary rightly points out the disconnect between the physical reality of the technology and the financial reality of the market. The author details how JDS Unifase (JDSU) became a "one-stop shop" for buyers like Lucent and Nortell, merging the passive components of JDS Fitel with the active lasers of Unifase.

"The company can now serve as a one-stop shop for buyers like Lucent and Nortell, who use those components to produce equipment to fulfill the seemingly insatiable demands of telecoms."

The author's description of the subsequent acquisition spree is particularly vivid. Asianometry writes, "JDSU, you should see them feast. They were like a mantis." This metaphor lands because it captures the predatory nature of the stock-swap deals that defined the era. The text details the absurdity of the valuations, noting that in mid-July 2000, JDSU's market cap hit $110 billion, surpassing GM and Ford combined, despite trailing revenues of only $1.4 billion. The author doesn't shy away from the sheer scale of the irrationality, citing the $41 billion acquisition of SDL, a company with just $25 million in profits. A counterargument worth considering is whether this bubble was "good" because it built the infrastructure for the modern internet, but Asianometry pushes back, noting the "social and economic annihilation of entire communities" left in the wake of the crash.

The Long Winter and the AI Rebirth

The narrative then pivots to the brutal correction. Asianometry writes, "Demand for fiber optic components was vanishing faster than an ice cube in the Sahara." The author details the cascading layoffs, from 700 contract workers to 16,000 jobs cut in a single year, painting a grim picture of the human cost. The text highlights the irony that while the stock plummeted from $293 to $2, the company remained cash-flow positive because the acquisitions were paid for in overvalued stock rather than debt. This financial nuance is often missed in broader summaries of the bubble, but Asianometry includes it to explain how the entity survived long enough to reinvent itself.

The most compelling part of the commentary is the transition from the telecom bust to the current AI boom. The author connects the historical dots, reminding readers that the fiber overhang from the early 2000s meant JDSU had to pivot to testing and maintenance, a move that kept the lights on. Now, the same fiber infrastructure is being repurposed for AI data centers. Asianometry writes, "But now, thanks to the massive AI data center boom, it is so back." This simple phrase carries the weight of the entire article: the technology didn't die; the business model just had to wait for the right application.

Critics might argue that the author glosses over the specific technical challenges of adapting old fiber for new AI protocols, but the broader point holds: the capital destruction of the bubble was a necessary, albeit painful, filter that left behind a resilient industry leader. The author's use of the "Intel of fiber optics" analogy for JDSU's peak dominance helps modern readers grasp the company's former stature, even if that dominance was built on shaky financial ground.

Bottom Line

Asianometry's strongest asset is its refusal to treat the telecom bubble as a mere footnote, instead treating it as the essential context for today's AI infrastructure boom. The piece's biggest vulnerability is a slight tendency to romanticize the "rebirth" without fully detailing the specific technical hurdles the company faces in the current AI landscape. However, the core verdict is clear: JDSU survived the bubble not by luck, but by the sheer utility of the fiber it helped lay, proving that while stock prices can be delusional, the physics of light remain constant.

From fiber to AI: A laser giant’s rebirth

Lumenum makes lasers, fiber optics, and some other stuff. It has a wild history. During the peak of the telecom bubble, this company with less than $2 billion in revenue was worth more than GM and Ford combined. After it all came crashing down, the company languished in obscurity for over a decade.

But now, thanks to the massive AI data center boom, it is so back. In today's video, the glorious rebirth of a fiber optic highf flyier and why. I want to thank Irrational, author of the irrational analysis newsletter, for inspiring me to do this video and working with me on the AI and laser section. Check out his newsletter in the description below.

Act one, scene one. We opened at Bell Northern Research or BNR, the research laboratory lab of the telecom giant Nortell in the 1970s. Canadians Yseph Strauss, Gary Duck, Philip Geral Jones, and Bill Sinclair are part of a team working on components for the first optical fiber technologies. Their efforts relate to reducing noise and increasing data capacity for carrying multiple video streams.

One technology they focused on was dense wavelength division multipplexing or DWDM. This lets a type of optic fiber called single mode fiber carry multiple signals simultaneously by encoding them in different light wavelengths. Such signals can be switched, routed and separated without fear of interference. Fiber optics are a wondrous technology but also have an infamous reputation as a destroyer of capital.

Prior to the 1990s, Nortell's fiber optic business lost money for 10 years straight. So Nortell somewhat understandably didn't want to make these fiber optic components in house. When that became clear, Strauss, Duck, Geralt Jones, and Sinclair left in 1981 to start JDS Optical. JDS Optical produced passive fiber optic network components, meaning those that control light without using any power.

Optical couplers, splitters, filters, and isolators. In 1990, they struck a distribution and technology sharing deal with the Japanese giant Furukawa Electric. Furukawa bought half of the company for about $9 million. As part of the deal, JDS Optical changed their name to JDS Fitel.

Vital being a Furukawa brand. Over the next few years, the company produced optical switches, couplers, and lasers, essential items for optical fiber networks. Overall, people knew them as a quiet, low-key company that kept their heads down. In this manner, the company emulated its co-founder and second CEO, ...
