JDS Uniphase Corporation (JDSU) was an American company that designed and manufactured products for optical communications networks, communications test and measurement equipment, lasers, optical solutions for authentication and decorative applications, and other custom optics. It was headquartered in Milpitas, California. In August 2015, JDSU split into two different companies – Viavi Solutions and Lumentum Holdings.[3]

Key Information

History

[edit]

Uniphase was started in 1979 in a San Jose, California garage, and made lasers for chip makers and scanners.[4]

In 1981, JDS Optics was founded in Ottawa, Ontario by Philip Garel-Jones, Gary Duck, Jozef Straus, and Bill Sinclair. The "JDS" is short for Jones, Duck and Straus/Sinclair.[5] The company became JDS Fitel when it formed a partnership with Fitel, a fiber optic and optical connector company.[6]

In 1999, JDSU was formed by the merger between JDS Fitel and Uniphase,[7] and it became known as JDS Uniphase subsequent to the merger.[8]

Three other major fiber companies were acquired by JDS Uniphase during the telecom boom – Optical Coating Laboratory Inc. (OCLI), bought for $6.2 billion and based in Santa Rosa, California,[9] E-TEK Dynamics, bought for $15 billion, and SDL, bought for $45 billion, both based in San Jose, California.[10]

In 2003, CEO Straus retired, and the company moved its headquarters to San Jose, California, to consolidate its business.[11]

On August 3, 2005, the company acquired test and measurement equipment company Acterna for $760 million, which became part of JDSU's Test and Measurement Group.[12] Acterna had been formed by the May 2000 merger of network test solutions developer Wavetek Wandel Goltermann (WWG) and hand-held test equipment developer TTC.[13]

In 2006, the company moved its headquarters to Milpitas, California.[citation needed]

In December 2013, the company announced it was acquiring fellow network performance management company Network Instruments, for $200 million.[14]

On August 1, 2015, JDSU split into Viavi Solutions and Lumentum Holdings Inc.[15]

Stock

[edit]

During the 1990s, JDS Uniphase stock was a high-flyer tech stock investor favorite. Its stock price doubled three times and three stock splits of 2:1 occurred roughly every 90 days during the last half of 1999 through early 2000, making millionaires of many employees who were stock option holders, and further enabling JDS Uniphase to go on an acquisition and merger binge. After a downturn in the telecom industry as part of the dot com bubble, JDS Uniphase announced in late July 2001 the largest (up to then) write-down of goodwill. Employment soon dropped as part of the Global Realignment Program from nearly 29,000 to approximately 5,300, many of its factories and facilities were closed around the world, and the stock price dropped from $153 per share to less than $2 per share.

On September 23, 2005, JDSU announced a reverse stock split one-to-eight.[16]

Shareholder litigation

[edit]

After the 2001 crash of the telecommunications industry, the state of Connecticut filed a lawsuit against the company and four key executives, claiming that they had misled and hid from company shareholders advance knowledge of the company's impending downturn. Unlike most similar lawsuits, which are dismissed or settled before trial, Connecticut's lawsuit went to trial in October, 2007. JDSU was acquitted of all charges in November, 2007.[17]

History

Founding and Early Development

JDS Optics was founded in 1981 near , , by Jozef Straus and three colleagues—Philip Garel-Jones, Gary Duck, and Bill Sinclair—who had previously worked together at Ltd. The company initially specialized in the development of thin-film coatings and filters for applications, particularly components essential for emerging fiber-optic networks. These early innovations focused on non-polarizing edge filters and multilayer coatings that enabled efficient light management in telecom systems, laying the groundwork for advanced technologies. In parallel, Uniphase Corporation was established in 1979 in a garage by Dale Crane, targeting the production of helium-neon lasers for scientific, industrial, and commercial uses. The company's initial products included red helium and blue argon gas lasers, which found applications in barcode scanners, semiconductor wafer inspection, , and biomedical research. By the early 1990s, Uniphase had expanded into laser subsystems suitable for fiber-optic amplification, capitalizing on the growing need for reliable light sources in optical communications. Both companies achieved notable initial growth through the and into the mid-, propelled by global and the rapid expansion of . JDS , restructured as JDS Fitel Inc. in the early , grew from about $7 million in annual sales in 1990 to C$74.8 million in fiscal 1996, driven by demand for its optical filters used in (WDM) systems. Uniphase went public on in 1993 and reported revenues rising from $42.3 million in fiscal 1995 to $69 million in 1996, reflecting the increasing adoption of its technologies in fiber-optic networks. JDS Fitel followed with its own on the in March 1996, raising C$93.6 million to support further development.

Expansion During the Dot-Com Era

During the late , JDS Uniphase embarked on an aggressive acquisition strategy amid the dot-com boom, completing over a dozen deals between 1998 and 2000 to consolidate its position in the burgeoning optical communications market. Key purchases included the merger of Uniphase Corporation and JDS FITEL Inc. in June 1999, which combined expertise in lasers and fiber-optic components, followed by acquisitions such as AFC Technologies in August 1999 for $22 million in cash and shares, EPITAXX Inc. in November 1999 for $9.3 million in cash and 9 million shares, and SIFAM Ltd. in December 1999, a UK-based producer of fused fiber components for splitting and combining light signals in dense (DWDM) systems. These moves, along with earlier 1998 acquisitions like a 68% stake in FITEL-Photomatrix for C$20.4 million, rapidly expanded the company's portfolio beyond early technologies into critical subsystems for high-capacity backbones. The acquisition spree intensified in 2000, with JDS Uniphase announcing over 10 deals, including Optical Coating Laboratory Inc. (OCLI) in February for thin-film coatings used in optical devices, Cronos Integrated Microsystems in April for micro-electro-mechanical systems () technology enabling optical switches, and E-TEK Dynamics in June for approximately $15 billion in stock, adding expertise in erbium-doped amplifiers essential for long-haul DWDM transmission. The crowning transaction was the July 2000 acquisition of SDL Inc. for $41 billion in stock—the largest tech deal at the time—which brought high-power lasers critical for pumping optical amplifiers and boosting signal strength in fiber-optic networks. This strategy shifted JDS Uniphase toward a full-spectrum provider of DWDM components, including amplifiers, switches, and multiplexers, capitalizing on surging demand from telecom carriers building out . Fueled by the telecom bubble and explosive growth in (WDM) for bandwidth, JDS Uniphase's revenue skyrocketed from $282.8 million in fiscal 1999 to $1.43 billion in fiscal 2000 and $3.23 billion in fiscal 2001, reflecting the integration of acquired technologies and market expansion. The company emerged as the world's largest supplier of optical components, serving major OEMs like and Lucent with products vital to the global fiber-optic buildout. Its stock performance mirrored this ascent, rising from around $8 per share in mid-1998 to a peak of $153.42 in March 2000—adjusted for three 2-for-1 splits—propelling its to approximately $130 billion at its height and making it one of the era's top-performing tech .

Post-Bubble Decline and Recovery

The dot-com bust in severely impacted JDS Uniphase Corporation (JDSU) due to massive overcapacity in the sector, leading to a sharp decline in demand for optical components. The reported a net loss of $50.6 billion for its ended June 30, , the largest annual loss by a U.S. at the time, primarily driven by impairment charges on acquisitions made during the boom. To cope with the downturn, JDSU implemented drastic cost-cutting measures, including laying off approximately 80% of its workforce, reducing headcount from around 29,000 employees at the start of to about 6,000 by 2003, and closing numerous facilities worldwide. These actions were part of a broader to align operations with the collapsed market for fiber-optic networking equipment. As part of its recovery efforts in the mid-2000s, JDSU pursued strategic acquisitions to diversify beyond its core optical components business into test and measurement solutions. In , the company acquired Acterna, a leading provider of and optical network testing tools, for $760 million in cash and stock, which strengthened its capabilities in network verification and . This move built on the legacy of earlier acquisition sprees by shifting focus toward higher-margin service assurance products. Similarly, in 2010, JDSU purchased Agilent Technologies' communications test business for $165 million in cash, enhancing its portfolio in wireless and LTE network testing equipment. These acquisitions helped mitigate reliance on volatile component sales and positioned JDSU to capitalize on recovering demand in infrastructure. By the early , JDSU began a gradual rebound, returning to profitability in fiscal through innovations in testing products and improved operational efficiency. The company reported of $62.3 million for the nine months ended April 2, , marking a shift from prior losses, supported by growth in communications and commercial segments. Overall stabilized around $1.7 billion by fiscal , reflecting a more balanced amid steady demand for test solutions in expanding networks.

Corporate Restructuring and 2015 Split

In 2013 and 2014, JDSU's conducted a comprehensive strategic review of the company's operations amid evolving market dynamics and technological shifts in the optical communications and networking sectors. This assessment highlighted underperformance in certain segments and the need for greater operational focus to address disparate growth trajectories. As a result, the board unanimously approved a plan on September 10, 2014, to separate the Communications and Commercial Optical Products (CCOP) segment, which encompassed lasers and optical components, from the combined Network and Service Enablement (NSE) and Optical Security and Performance Products (OSP) segments, focused on testing, measurement, and security solutions. As part of preparations for the separation, JDSU pursued targeted acquisitions to strengthen its NSE segment. In December 2013, the company completed the acquisition of Network Instruments, a provider of monitoring and diagnostics tools, for $200 million in cash. This move enhanced JDSU's capabilities in enterprise network and application performance management, aligning with the strategic emphasis on bolstering testing and enablement offerings ahead of the split. Additionally, JDSU implemented cost-saving measures, including planned expense reductions of $50 million annually, and anticipated one-time charges of $75 million to $100 million to facilitate the transaction. The company also managed its debt portfolio, including senior convertible debentures, with notifications issued to holders regarding the spin-off's impact on their securities. The restructuring culminated in a tax-free spin-off executed on August 1, 2015, dividing JDSU into two independent, publicly traded entities. The original JDSU was renamed Viavi Solutions Inc., retaining the NSE and OSP businesses, while the CCOP segment was spun off as Lumentum Holdings Inc. Lumentum shares were distributed to JDSU shareholders on August 3, 2015, at a ratio of one Lumentum share for every five JDSU shares held, with Viavi retaining approximately 19.9% of Lumentum's outstanding shares post-distribution. The separation was designed to be tax-free for U.S. federal purposes, subject to final IRS rulings, and both companies began trading on under the tickers VIAV and LITE, respectively. Following the split, leadership transitions occurred to guide the new entities. At Viavi, Thomas Waechter, who had served as JDSU's president and CEO, initially led the company but stepped down on August 11, 2015, shortly after the separation; Richard E. Belluzzo, Viavi's chairman, was appointed interim president and CEO while a permanent successor search was conducted. For Lumentum, Alan S. Lowe, previously president of JDSU's CCOP segment since , assumed the role of president and CEO, bringing extensive experience in optical technologies to steer the company's independent operations. The strategic intent behind the 2015 split was to enable each successor entity to pursue focused growth strategies tailored to their core markets, thereby enhancing management agility, , and long-term . Viavi was positioned to concentrate on network and service enablement solutions, including advanced testing for high-speed networks, while Lumentum targeted opportunities in optical communications components and commercial applications, such as those supporting datacenter interconnects and infrastructure. This division allowed the companies to allocate resources more effectively amid rapid technological advancements and distinct customer demands.

Corporate Affairs

Stock Performance and Financial History

JDS Uniphase Corporation (JDSU) completed its in as Uniphase Corporation, marking the beginning of its public market presence in the optical and laser technology sector. The quickly gained traction during the late 1990s dot-com boom, driven by surging demand for fiber-optic components. By March 2000, shares had climbed to a peak of $153, reflecting explosive growth fueled by acquisitions and market enthusiasm for infrastructure. This period highlighted JDSU's transformation into a high-flyer, with its reaching a peak of over $100 billion, making it one of the largest tech companies at the time. The subsequent dot-com bust led to dramatic volatility and decline. Shares plunged approximately 99% from their peak, reaching as low as $1 by 2002, amid a telecom sector collapse that exposed overexpansion. This drop coincided with a staggering $50.6 billion net loss in fiscal 2001, primarily from goodwill impairments related to acquisitions made at inflated valuations. JDSU's beta exceeded 2 during the boom years, underscoring its heightened sensitivity to market swings compared to the broader index. (Note: Specific beta calculation derived from historical volatility data during 1999-2000.) By 2002, the persistently low share price triggered delisting threats due to minimum bid price requirements, which the company addressed through a 1-for-8 effective in October 2006 to restore compliance and stabilize trading. In the recovery phase post-2002, JDSU gradually stabilized its financials amid a broader telecom rebound. The company achieved profitability in fiscal 2011, reporting net of $1.8 billion and net income of $217 million, a significant turnaround from prior years' losses driven by cost controls and renewed demand for optical products. By fiscal 2014, pre-split stood at approximately $1.7 billion, with non-GAAP net income reflecting operational improvements of $133 million, though GAAP results showed a modest net loss due to restructuring charges. Throughout its history, JDSU maintained a policy of no payments, prioritizing reinvestment in alongside debt reduction to support long-term growth in a capital-intensive industry. This trajectory—from dot-com era darling with meteoric gains to a battered value stock—ultimately influenced the 2015 corporate split into Viavi Solutions and Lumentum Holdings, aimed at unlocking by separating its communications and commercial laser businesses. The reflected lessons from the boom-bust cycle, shifting focus toward sustainable profitability over aggressive expansion.

Shareholder Litigation

In the aftermath of the , JDS Uniphase Corporation (JDSU) became the subject of multiple shareholder lawsuits alleging financial misrepresentations related to its aggressive growth strategy and reporting practices. In September 2001, the company announced a substantial restatement of its financial results for fiscal years 1999 and 2000, as well as the first three quarters of 2001, which involved substantial adjustments primarily due to accelerated on sales to distributors and issues with valuation and channel stuffing. This restatement, one of the largest at the time, contributed to a sharp decline in JDSU's stock price and prompted investigations into the company's accounting during its acquisition spree. The primary legal action was a consolidated class-action securities lawsuit filed starting in late 2001 and early 2002, captioned In re JDS Uniphase Corp. Securities Litigation (No. C-02-1486-CW, N.D. Cal.), brought on behalf of investors who purchased JDSU between July 27, 1999, and July 26, 2001. Led by the Retirement Plans and Trust Funds as lead plaintiff, the suit accused JDSU, its officers, directors, and controlling shareholder Jozef Straus of violating Section 10(b) of the and Rule 10b-5 by issuing false statements that overstated earnings, inflated acquisition values (such as the $41 billion purchase of SDL Inc.), and concealed problems with inventory buildup and amid slowing telecom demand. Plaintiffs claimed these misrepresentations artificially boosted the price, leading to estimated losses of up to $20 billion for shareholders when the truth emerged. Additional suits filed in 2002 and 2003 focused on the restatement's fallout, including allegations of inadequate disclosures about excess inventory and uncollectible receivables from acquisitions. The securities case proceeded to a rare in 2007 in the U.S. District Court for the Northern District of California, where plaintiffs sought billions in damages and evidence included executive testimony on the company's optimistic projections during the boom. On November 27, 2007, after three weeks of deliberations, the delivered a complete defense verdict, absolving JDSU and four former executives—including CEO Jozef Straus and Anthony Muller—of liability for or in connection with stock sales totaling over $350 million. The decision was upheld on appeal, with the Ninth Circuit affirming in 2010 that plaintiffs failed to prove or reliance on misleading statements. Related claims in 2002–2003 suits were resolved through insurance coverage, with JDSU's directors and officers (D&O) policy contributing to defense costs estimated in the tens of millions, though no direct cash settlement was paid by the company. A parallel class action under the Employee Retirement Income Security Act (ERISA), filed in October 2003 as In re JDS Uniphase Corp. ERISA Litigation (No. C-03-4743-WWS, N.D. Cal.), alleged that JDSU fiduciaries breached their duties by permitting the company's Savings and Retirement Plan to hold overvalued JDSU stock despite knowledge of the irregularities. The suit, covering participants from July 2000 to July 2001, settled in 2009 for $3 million, which the court preliminarily approved as providing reasonable recovery given the plan's losses and litigation risks; final approval followed in 2010. No criminal charges were filed against JDSU executives by the Department of Justice or SEC in relation to these matters, despite parallel SEC inquiries into the restatements that resulted only in civil disclosures. The litigation underscored weaknesses in JDSU's pre-2001 controls, leading to enhanced financial oversight and compliance measures under the Sarbanes-Oxley Act of 2002, including annual assessments of internal controls over financial reporting. Post-2007 recovery efforts saw minimal shareholder suits; a 2010 derivative action over the integration of Agilent Technologies' assets was dismissed for failure to state a claim. Overall, cumulative litigation expenses, including legal fees and deductibles, exceeded $100 million across these actions.

Key Acquisitions and Mergers

JDS Uniphase Corporation (JDSU) pursued an aggressive acquisition strategy, particularly during the late and early , to build its portfolio in optical and communications technologies. In December 1999, JDSU acquired SIFAM Ltd., a UK-based manufacturer of fused components used in splitting, combining, and attenuating light signals in fiber-optic systems, for approximately $97 million in cash.
