                  Ciena Reports Unaudited Fiscal Fourth Quarter
      and Year-End Results; Quarterly Revenue of $118.2 Million Represents
      44% Year-over-Year Growth; Gross Margin Improves More Than 500 Basis
                              Points Sequentially


    LINTHICUM, Md.--(BUSINESS WIRE)--Dec. 8, 2005--Ciena(R) Corporation
(NASDAQ:CIEN), the network specialist, today announced unaudited
results for its fiscal fourth quarter and year ending October 31,
2005.
    Ciena's unaudited fiscal fourth quarter revenue was $118.2
million, representing a 7% sequential increase from fiscal third
quarter revenue of $110.5 million and an increase of 44% over revenue
of $82.0 million for the same period a year ago. For the twelve months
ending October 31, 2005, Ciena's unaudited revenue was $427.3 million,
representing an increase of 43% over revenue of $298.7 million for the
same year-ago period.
    "In the last year, Ciena's employees have demonstrated
extraordinary focus on execution of our strategy and, as a result,
have driven the Company's significant revenue growth and meaningful
financial performance improvement," said Ciena CEO and President, Gary
Smith. "With our seventh sequential quarter of revenue growth, and
with continued gross margin improvement, our fiscal fourth quarter's
results demonstrate Ciena's steady progress toward profitability and
positive cash flow, and more importantly, our continued progress
toward future earnings growth."
    On the basis of generally accepted accounting principles (GAAP),
Ciena's unaudited fiscal fourth quarter net loss was $252.9 million,
or a net loss of $0.44 per share. This loss compares to a GAAP net
loss of $495.1 million, or a net loss of $0.87 per share, in the same
period a year ago. In accordance with Statement of Financial
Accounting Standards (SFAS) 142, an accounting rule that requires
annual testing of possible goodwill impairment, the Company's
unaudited fiscal fourth quarter 2005 GAAP net loss reflects a goodwill
impairment loss of $176.6 million, representing $0.31 of the quarter's
total GAAP net loss per share.
    For the twelve months ending October 31, 2005, Ciena's GAAP net
loss was $435.7 million, or a net loss of $0.76 per share. This
compares to a GAAP net loss of $789.5 million, or a net loss of $1.51
per share, in the same twelve-month period a year ago.

    Non-GAAP Presentation of Results

    In evaluating the operating performance of its business, Ciena's
management excludes certain charges or credits that are required by
GAAP. These items, which are identified in the table that follows (in
thousands except per share data), share one or more of the following
characteristics: they are unusual, and Ciena does not expect them to
recur in the ordinary course of its business; they do not involve the
expenditure of cash; they are unrelated to the ongoing operation of
the business in the ordinary course; or their magnitude and timing is
largely outside of the Company's control.

    Adjusting Ciena's unaudited fiscal fourth quarter 2005 GAAP net
loss of $252.9 million for the items noted above would reduce the
Company's net loss in the quarter to $11.6 million, or a loss of $0.02
per share. This compares with an adjusted net loss of $33.9 million,
or a loss of $0.06 per share, in the same year-ago period.
    Adjusting Ciena's unaudited twelve-month fiscal year 2005 GAAP net
loss of $435.7 million for the items noted above would reduce the
Company's net loss for the year to $89.4 million, or a loss of $0.16
per share. This compares with an adjusted net loss of $158.6 million,
or a loss of $0.30 per share, in the same year-ago period.
    These adjustments are not in accordance with GAAP, and making
these adjustments may not permit meaningful comparisons to other
companies.

Fourth Quarter 2005 Operational Highlights

    --  Ciena delivered sequential revenue growth of 7% and
        year-over-year revenue growth of 44%.

    --  As a result of continued product and manufacturing-related
        cost reductions and product mix in the quarter, overall gross
        margin improved more than 500 basis points, from 34.1% in the
        fiscal third quarter to 39.9% in the fiscal fourth quarter.

        --  Improved product gross margin from 35.6% in the fiscal
            third quarter to 42.2% in the fiscal fourth quarter.

        --  Improved services-related gross margin from 22.5% in the
            fiscal third quarter to 24.5% in the fiscal fourth
            quarter.

    --  Ciena used $8.9 million in cash for operations in the fiscal
        fourth quarter compared to fiscal third quarter cash use of
        $39.3 million (which was inclusive of a $12.9 million
        semi-annual interest payment on the Company's outstanding
        3.75% convertible notes).

    --  Ciena ended the fiscal fourth quarter 2005 with cash and
        short- and long-term investments of $1.11 billion.

    --  Ciena expanded the Company's global presence with the launch
        of a research and development centre located in Gurgaon,
        India.

Fourth Quarter 2005 Customer and Product Highlights

    --  Ciena strengthened its relationship with EMC Corporation,
        adding the Ciena CN 4200(TM) FlexSelect Advanced Services
        Platform to the EMC(R) Select Program and joining the EMC
        Authorized Services Network's (ASN) Solution Alliances.

    --  Telecom Ottawa announced the availability of a suite of SONET,
        WDM and storage extension services enabled by Ciena platforms
        and designed to provide Canadian federal government agencies,
        as well as enterprises and carriers, with reliable,
        high-performance 10-Gigabit Ethernet (GbE) connectivity
        throughout the Ottawa metropolitan region.

    --  Adelphia Communications Corporation, a leading U.S. cable
        provider, deployed Ciena's optical Ethernet platforms across
        western New York to interconnect 106 school districts serving
        189,000 students with a wide range of applications for
        distance learning, including video conferencing and broadband
        data networking.

    --  HSE&DEM, the Republic of Slovenia's largest producer of
        electricity, selected Ciena's next-generation optical
        multiservice switches, optical multiplexers, storage extension
        platforms and network management systems to interconnect its
        locations nationwide with a reliable, high-performance
        Adaptive WAN(TM) (wide area network) to deliver IT services
        used in the production and delivery of electrical energy to
        customers.

    --  Ciena successfully completed interoperability testing and
        qualification of its ONLINE Metro(TM) Multiservice DWDM
        Platform for IBM GDPS eServer zSeries mainframe environments.
        IBM's validation of ONLINE Metro was based upon the successful
        completion of test scenarios on IBM zSeries mainframes deemed
        vital to GDPS operation.

    Business Outlook

    "We continue to see signs of improving overall market strength and
expect our network specialist approach will enable us to continue to
grow faster than the market in 2006," said Smith. "In addition, as a
result of relentless execution across the Company, including our
ongoing efforts to reduce product and manufacturing-related costs, we
expect to demonstrate gross margin improvement over the course of the
year," said Smith. "Provided we execute on plan, we believe we are
well positioned to achieve profitability on an as-adjusted basis
during a quarter prior to the end of fiscal 2006."
    "We expect our fiscal first quarter revenue will be flat to up
slightly from our fiscal fourth quarter revenue, and we expect to see
sequential gross margin improvement in our fiscal first quarter,"
concluded Smith.

Appendix A

The adjustments management makes in analyzing Ciena's fiscal fourth
quarter 2004 and 2005 GAAP results are as follows:

    --  Stock compensation costs - a non-cash expense (unrelated to
        share-based payment expense under SFAS 123(R) which the
        Company adopted in its fiscal first quarter 2006), which
        arises under GAAP accounting from the assumption of unvested
        stock options issued by any companies we acquire and which the
        Company feels is not reflective of its ongoing operating
        costs.

    --  Amortization of intangible assets - a non-cash expense arising
        from acquisitions of intangible assets, principally developed
        technology, which Ciena is required to amortize over its
        expected useful life and which the Company feels is not
        reflective of its ongoing operating costs.

    --  In-process research and development - a non-recurring expense
        related to in-process technology that, as of the date of
        acquisition, has not reached technological feasibility and has
        no alternative future use.

    --  Restructuring costs - non-recurring charges incurred as the
        result of reducing the size of the Company's operations to
        align its resources with the reduced size of the
        telecommunications market as well as the result of targeting
        new segment opportunities within the overall market, which the
        Company feels are not reflective of its ongoing operating
        costs.

    --  Goodwill impairment - non-cash expense resulting from the
        decline in the forecasted market demand for the Company's
        products.

    --  Long-lived asset impairments - non-recurring charges, incurred
        as a result of excess equipment classified as held for sale
        which the Company feels are not reflective of its ongoing
        operating costs.

    --  Recovery of use tax payments - a non-recurring gain unrelated
        to normal operations

    --  Provision for (recovery of) doubtful accounts - a
        non-recurring charge unrelated to normal operations resulting
        from an assessment of doubtful payment due to a customer's
        financial condition.

    --  Accelerated amortization of leasehold improvements - a
        non-cash expense related to the closure of our San Jose,
        California facility.

    --  Loss on equity investments, net - a non-recurring gain or loss
        related to changes in the value of the Company's equity
        investments which the Company feels is not reflective of its
        ongoing operating costs.

    --  Loss (gain) on extinguishment of debt - a non-recurring gain
        or loss related to the early extinguishment of outstanding
        debt.

    --  Income tax benefit on adjusted net loss - the income tax
        charge or benefit on the adjusted net loss, which is a
        necessary adjustment for consistency. The Company currently
        has a full valuation allowance for GAAP reporting purposes and
        accordingly does not recognize a tax benefit for losses
        generated.
