Exemplifies Corporation's Overall Commitment to Quality

Ottawa, Ontario and San Jose, California - February 20, 2001 -JDS Uniphase Corporation (NASDAQ: JDSU; TSE: JDU) became the first TL 9000-Hardware/ISO 9001:1994 certified producer of micro-electro-mechanical systems (MEMS) with the certification of its MEMS division located in Research Triangle Park, NC.

TL 9000, developed by the Quality Excellence for Suppliers of Telecommunications (QuEST) Forum, is the telecommunications industry's extension to ISO 9001:1994. The purpose of TL 9000 is to define the quality management system requirements for the design, development, production, delivery, installation and maintenance of products and services for telecommunications. Included in TL 9000 are performance and cost-based metrics that measure reliability and quality performance of the products and services.

"Meeting the requirements for the TL 9000-Hardware quality management system at our MEMS facility in December, 2000, represents a major milestone in our path toward introducing MEMS-based products into our industry," remarked Jesko von Windheim, General Manager of the MEMS division. "This achievement also exemplifies our company's overall commitment to quality."

As part of JDS Uniphase's quality program, it has established a Corporate Reliability Council to set policy, maintain standards and establish best practice methods for the company's reliability and quality efforts including product qualifications. As a part of this effort, cross-functional teams with representation from manufacturing, development, and reliability engineering are established from initiation of a design activity. These teams are subsequently responsible for ensuring that reliability considerations are addressed during the concept, development and pilot phases for new product introductions.

One approach being used by the Company to gain greater understanding about the development of highly reliable products is subjecting components to extreme environmental conditions beyond current reliability requirement standards and forcing failures during the design and development phases. "We are looking to continually improve all our products and the processes used to assemble them - from design throughout manufacturing," added Tom Adda, Director of Quality Assurance for Amplifier Components and a member of the JDS Uniphase Corporate Reliability Council.

With a unique "inside out" viewpoint, the JDS Uniphase Corporate Reliability Council is intended to complement industry-wide certification programs such as TL 9000 with particular emphasis on customer satisfaction. Discovering new and better ways of delivering reliable products to meet or exceed customer expectations is the ultimate objective of this company-wide initiative.
