OPTICAL NETWORKING SYSTEMS

Optical networking increases the capacity of the fiber in a network, enabling service providers to carry more of their customers’ voice, data and video signals over the same infrastructure. Optical networking relies on wavelengths and fibers to move massive amounts of voice and data. A wavelength can carry voice, video or data traffic from an optical carrier (OC)-3 or synchronous transfer mode (STM)-1 (up to two thousand simultaneous phone conversations or Internet connections) up to OC-768 or STM-256. A fiber can carry anywhere from one to 160 wavelengths, depending on the type of equipment used to terminate the fiber.

Tellabs’ optical networking systems are designed to help service providers lower costs, generate more revenues and efficiently manage bandwidth as the end-user demand for communication services grows. The Company’s optical networking systems consist of technologically sophisticated digital cross-connect, transport switching and optical transport systems. These transmission systems are designed to meet or exceed domestic and international industry standards. Product offerings include the Tellabs 5000 series of digital-cross connect systems, the Tellabs 6400 series of transport products, the Tellabs 6500 transport switch and the Tellabs 7100 series of optical transport systems.

A digital cross-connect system is a high-speed data channel switch, which connects transmission paths based on network needs, rather than call-by-call. Digital cross-connect systems manage and route network traffic and combine, consolidate and segregate signals to maximize efficiency. The Tellabs 5000 series of digital cross-connect systems operate under software control and are typically used to build and control the narrowband and wideband transmission infrastructure of telecommunication service providers. These products augment the ability of service providers to provide current, emerging and future services to business and residential customers.

Telecommunication managers utilize the digital cross-connect systems to generate revenue and to reduce cycle time while minimizing capital and operating expense. Key applications include centralized and remote testing of transmission facilities, grooming of voice, data, and video signals, automated provisioning of new services and restoration of failed facilities. All of the Company’s systems include a feature for monitoring facility performance, which reduces troubleshooting time in a complex network. The user can detect the early warnings of facility degradation rather than reacting to a network outage. These systems also convert international to domestic transmission and signaling standards.

The Tellabs 5000 series digital cross-connect systems vary in switching rate and facility interface speed. The Tellabs 5300 line of narrowband cross-connect systems is the highest density narrowband system on the market with the ability to satisfy small cross-connect application requirements. More than 1,000 Tellabs 5300 systems have been implemented in wireless/mobile networks The Company's flagship Tellabs 5500 digital cross-connect system is one of the industry’s highest capacity wideband digital cross-connects. The system efficiently grooms voice and data traffic over a SONET-based network. More than 4,000 Tellabs 5500 systems have been deployed in a variety of networks including local telephone service, long distance, wireless, private and emerging networks across the United States. With its scalability and carrier-class architecture, the Tellabs 5500 system helps service providers reduce equipment and maintenance costs while maximizing network profitability.

The Tellabs 6400 product line, obtained in the acquisition of Ocular Networks, Inc., in January 2002, is also designed for use in the metro optical networking market. The Tellabs 6400 transport switch increases network utilization efficiency in Tier 2 and Tier 3 offices by integrating cross-connect technology, add-drop multiplexing and highly efficient data switching for Internet protocol (IP) and Ethernet traffic. The Tellabs 6410 transport edge node is a compact, low-cost full SONET add/drop multiplexer system for time division multiplex (TDM) access and data services. By combining TDM and Ethernet interfaces with high-speed optical or electrical transport, carriers can achieve a cost-effective solution to link the new edge of the metro network with the dense metro core.

The Tellabs 6500 transport switch is a broadband transport platform that performs bandwidth grooming, add-drop multiplexing (ADM) and cross-connections at higher speeds than the 5500 series products. The new Tellabs MetroVantage™ solution extends this capability to remote locations via metro aggregation/backhaul and virtual cross-connections. The Tellabs 6500 system’s redundant, carrier-class architecture ensures reliability during operation and service continuity during system expansion. The Tellabs 6500 system is fully bi-directional and non-blocking/non-stranding, enabling addition of port complexes up to the switch core capacity in any combination of port bandwidths. This system supports hitless scalability from 20 gigabits per second to 1.2 terabits per second, and is expandable from the smallest system to the largest.

The Tellabs 7100 optical transport system is designed for use in the metropolitan (metro) optical networking market, to enable service providers to deliver high-speed broadband services to Internet service providers and Fortune 500 companies, helping to alleviate the bandwidth bottlenecks of the Internet “on ramps.” The system accomplishes this by utilizing densewavelength-division multiplexing (DWDM) technology to increase the capacity of a network. DWDM is the process of increasing the amount of traffic a single fiber can carry. The Tellabs 7100 system utilizes DWDM to increase an individual fiber’s capacity up to 32 times and when used in conjunction with other Tellabs solutions, enables end-to-end fiber and lightpath management.

Optical networking system products accounted for approximately 44%, 55% and 64% of sales for 2002, 2001 and 2000, respectively.

BROADBAND ACCESS

The Company’s broadband access systems consist primarily of the Tellabs 8100 and Tellabs 6300 series of managed access and transport systems, the Tellabs 7200 optical transport system and the Tellabs 2000 family of cable telephony distribution systems. The Company’s broadband access solutions consist of managed access and transport systems used to deliver wireless and business services as well as an access product designed to deliver telephone and data services over cable television networks.

The Tellabs 8000 series of managed access systems is designed for the connectivity services segment of the overall Europe, Middle East, Africa, Asia Pacific and Latin America business services market, which includes business-class Internet connectivity and managed data networks.

Broadband Access products accounted for approximately 35%, 24% and 22% of sales in 2002, 2001 and 2000.

VOICE-QUALITY ENHANCEMENT

The Company’s voice-quality enhancement systems consist primarily of the Tellabs 3000 family of broadband and narrowband echo cancellers and Tellabs voice-quality enhancement (VQE) solutions that enable wireless and wireline providers to improve voice quality in long distance, wireless and private networks.

The Tellabs 3000 series of echo cancellers operate in a variety of network environments to ensure that a subscriber’s phone call is echo-free. The VQE solutions are application-specific software that operate seamlessly with the Tellabs 3000 family of echo cancellers to optimize voice clarity for improved customer satisfaction. Tellabs VQE products primarily address the needs of cellular companies, ILECs and IXCs, both domestically and internationally. Over 300 customers in 70 countries rely on Tellabs echo canceller and VQE solutions.

In the case of wireline customers, the ability to control the clarity of speech quality is becoming more and more difficult, because of the deregulation of networks and the move from circuit-based to cell- and packet-based networks. These networks introduce delays and other issues that are not present in circuit-based calls, such as inconsistent speech-level control during calls. In the case of wireless operators, to compete with wireline operators for call revenues, the clarity of a mobile call must be as good as a wireline call. These changes have resulted in a move away from pure echo cancellation, to providing echo cancellation as a platform for voice-quality enhancing software, such as level control and noise reduction. This development in the market has opened up opportunities, not just to provide solutions to the wireline and wireless operators worldwide, but also to the manufacturers of telecommunications products worldwide, who integrate these voice-quality enhancing solutions into their products. Competition is driving many wireline and wireless customers to re-evaluate and upgrade their existing infrastructure, based on the voice-enhancing technology solutions now available. Tellabs VQE solutions include Tellabs Noise Reduction (TNR), which reduces background noise in mobile calls; Tellabs Level Control (TLC), which addresses voice level variations by automatically compensating for high or low audio levels on a cell-by-cell basis; and Tellabs Acoustic Control (TAC), which eliminates acoustic echo originating from digital mobile handsets and hands-free kits.

The Tellabs 3100S VQE system combines an echo canceller and a fully functional digital cross-connect, along with optional voice-quality enhancements, to offer digital wireless and long distance service providers improved voice quality and enhanced network performance.

In 2002, the Company introduced the Tellabs 3600 OC-3 broadband echo control solution, which improves voice quality and enhances network performance for digital wireless and long-distance service providers.

Voice-quality enhancement products accounted for approximately 5% of sales in 2002 and 6% of sales in both 2001 and 2000.

The Company also owns three office buildings in Espoo, totaling 132,000 square feet, which contain production, research and development and administrative functions.

Additionally, the Company has two locations that are classified as “held for sale” as of December 27, 2002. These locations include 19.1 acres of land with three buildings totaling 220,000 square feet in Lisle, Illinois, and a 124,000-square foot building on approximately 76 acres of land in Round Rock, Texas.

In Shannon, Ireland, the Company owns a 135,000-square foot manufacturing facility, which is built on land obtained through a long-term lease entered into during 1997. The Company is currently in the process of finding a buyer for this building.

Significant facilities leased by the Company include: a facility in Ashburn, Virginia (72,000 square feet) for research and development; two locations in Espoo, Finland (60,000 square feet, total) housing administrative and engineering functions; and locations in Oulu, Tampere, and Verkaus, Finland (94,000 square feet, total) for research and development.

The Company owns substantially all of the equipment used in its business. The Company believes that its facilities are adequate for the level of production anticipated in 2003, and that suitable additional space and equipment will be available to accommodate expansion as needed.

ITEM 3. LEGAL PROCEEDINGS

On June 18, 2002, a class action complaint was filed in the United States District Court of the Northern District of Illinois against the Company, Michael Birck, and Richard Notebaert (former CEO, Director, and President of the Company). Thereafter, eight similar complaints were also filed in the United States District Court of the Northern District of Illinois against the same defendants. All nine of these actions were subsequently consolidated, and on December 3, 2002, a consolidated amended class action complaint was filed against the Company, Mr. Birck, Mr. Notebaert, and certain other of the Company’s current or former officers and/or directors. The consolidated amended complaint alleges that during the class period (December 11, 2000-June 19, 2001) the defendants allegedly violated the federal securities laws by allegedly making materially false and misleading statements, including, among other things, providing revenue forecasts that plaintiffs allege were false and misleading and allegedly reporting overstated revenues for the fourth quarter of the year 2000 in the Company’s financial statements. Further, certain of the individual defendants are alleged to have violated the federal securities laws by trading Company securities while allegedly in possession of material, non-public information about the Company pertaining to these matters. No specific amount of damages has been claimed. On January 17, 2003, the Company and the other named defendants filed a motion to dismiss the consolidated amended class action complaint in its entirety. The Company intends to defend this action vigorously.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The Management’s Discussion and Analysis of Financial Condition and Results of Operations on pages 20 through 27 of the Annual Report are incorporated herein by reference. This information is also included in Exhibit 13, as filed with the SEC.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Investments in marketable securities

During the normal course of business, the Company invests a portion of its cash and cash equivalents in marketable securities. The Company accounts for these investments using the guidance in Statement of Financial Accounting Standards (SFAS) No. 115, "Accounting for Certain Investments in Debt and Equity Securities" and its related interpretive guidance. All securities in the Company’s short-term marketable securities portfolio are considered available-for-sale securities and are marked-to-market on a monthly basis with the resulting unrealized gains and losses, net of deferred taxes, reported as a separate component of stockholders’ equity.

In accordance with SFAS No. 115, when the Company determines that a decline in the fair value of a security is other than temporary, the Company will record an impairment loss to adjust the security to its new, lower market value. In assessing whether a decline in market value for a security is considered other than temporary, the Company examines a variety of factors, including: current and anticipated macro-economic conditions, the outlook for the particular industry, the long-term business outlook for the investee, the amount of time the investment’s fair value has been below cost and the Company's liquidation strategy with respect to the particular investment.

At December 27, 2002, and December 28, 2001, the Company’s short-term marketable securities consisted of the following:

(In millions)	Amortized Cost	Unrealized Gain/(Loss)	Market Value
2002
State and municipal securities	$149.9	$1.6	$151.5
Preferred and common stocks	47.9	1.5	49.4
U.S. government and agency debt obligations	212.5	4.9	217.4
Corporate debt obligations	57.4	2.4	59.8
Foreign government obligations	15.9	0.1	16.0
Foreign bank obligations	71.5	–	71.5
	$555.1	$10.5	$565.6
2001
State and municipal securities	$135.9	$1.8	$137.7
Preferred and common stocks	93.7	2.6	96.3
U.S. government and agency debt obligations	65.9	2.1	68.0
Corporate debt obligations	55.8	0.7	56.5
Foreign bank obligations	41.3	(0.1)	41.2
	$392.6	$7.1	$399.7

The Company’s preferred and common stock portfolio consists of investments in preferred securities of various public companies and governmental agencies, investments in mutual funds that invested in preferred stock holdings and investments in common shares of publicly traded technology companies.

The Company also maintains investments in start-up technology companies and partnerships that invest in start-up technology companies. These investments are recorded in Other Assets at cost, which approximates fair market value. At December 27, 2002, and December 28, 2001, these investments totaled $9.0 million and $36.0 million, respectively. During 2001, the Company recorded a $12.8 million pre-tax gain on the sale of a certain equity investment.

Management conducts a quarterly review of each investment in its portfolio, including historical and projected financial performance, expected cash needs and recent funding events. Other-than-temporary impairments are recognized if the market value of the investment is below its cost basis for an extended period of time or the issuer has experienced significant financial declines or difficulties in raising capital to continue operations. Other-than-temporary impairments were $29.6 million in 2002 and $25.9 million in 2001.

Financial Instruments

The Company conducts business on a global basis in several major currencies and is subject to the risks associated with fluctuating foreign exchange rates. In response to this, the Company developed a foreign currency exposure management policy with the objective of mitigating financial exposure to changing foreign exchange rates resulting from nonfunctional currency receivables and payables that are expected to be settled in one year or less. The Company utilizes derivatives, primarily foreign currency forward contracts, to manage its foreign currency exposure. The Company does not engage in hedging specific individual transactions, but rather uses derivatives to manage overall exposure levels for a specific currency. Gains and losses related to these derivatives are recorded to the Consolidated Statement of Operations each period.

The Company’s policy is to hedge 90% of the calculated exposure. Foreign currency forward contracts are executed weekly with the final contracts for each period executed one week before the end of the period. As a result of this timing, additional nonfunctional foreign currency transactions can occur during the last week of the period that could cause the Company’s hedge percentage at the end of the period to be greater or less than the 90% target. The Company enters into forward exchange contracts only to the extent necessary to meet its overall goal of minimizing nonfunctional foreign currency exposures. The Company does not enter into hedging transactions for speculative purposes. The Company’s foreign currency exposure management policy and program remained unchanged during 2000, 2001 and 2002, and no significant changes are currently planned.

In accordance with SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activity,” all forward exchange contracts are recorded on the balance sheet at fair value. Forward exchange contracts receivable are included in other current assets, while forward exchange contracts payable are included as part of accrued liabilities in the Consolidated Balance Sheet. Changes in the fair value of these instruments are included in earnings, as part of other income and expense, in the current period. The Company had a net gain of $5.5 million on forward exchange contracts in 2002. Net losses on forward exchange contracts were $4.7 million and $1.8 million 2001and 2000, respectively. The Company's current hedging practices do not qualify for special hedge accounting treatment as prescribed in SFAS No. 133 since hedges of existing assets or liabilities that will be remeasured with changes in fair value reported currently in earnings are specifically excluded.

Derivative financial instruments involve elements of market and credit risk not recognized in the financial statements. The market risk that results from these instruments relates to changes in the foreign currency exchange rates, which is generally offset by movements in the value of the underlying assets or liabilities being held. Credit risk relates to the risk of nonperformance by a counterparty to one of the Company's derivative contracts. The Company does not believe there is a significant credit risk associated with its hedging activities because counterparties are all large international financial institutions with high credit ratings. In addition, the Company also limits the aggregate notional amount of agreements entered into with any one financial institution in order to mitigate credit risk.

The table that follows presents a summary of the notional value and the fair value of forward exchange rate contracts for each currency in which the Company had hedged exposure at December 27, 2002, and December 28, 2001. The principal currencies currently being hedged by the Company are the British pound, Danish krone, Euro, Mexican peso and U.S. dollar. The notional amounts shown are the U.S. dollar values of the agreed-upon amounts in each foreign currency that will be delivered to a third-party on the agreed-upon date.
