</FONT>

<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;145 of the Delaware General Corporation Law permits
indemnification of officers, directors and other corporate agents under certain
circumstances and subject to certain limitations. The Registrant&#146;s Third
Amended and Restated Certificate of Incorporation and bylaws provide that the
Registrant shall indemnify its directors, officers, employees and agents to the
full extent permitted by Delaware General Corporation Law, including in
circumstances in which indemnification is otherwise discretionary under
Delaware law. In addition, the Registrant has entered into separate
indemnification agreements with its directors, officers and certain employees
which require the Registrant, among other things, to indemnify them against
certain liabilities which may arise by reason of their status or service (other
than liabilities arising from willful misconduct of a culpable nature) and to
maintain directors&#146; and officers&#146; liability insurance, if available on
reasonable terms. The Registrant has directors&#146; and officers&#146; liability
insurance with up to $100&nbsp;million coverage per year. These indemnification
provisions and the indemnification agreement between the Registrant and its
officers and directors may be sufficiently broad to permit indemnification of
the Registrant&#146;s officers and directors for liabilities (including
reimbursement of expenses incurred) arising under the Securities Act.

<P align="center"><FONT size="2"><B>*&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; *</B>
</FONT>
<P align="left"><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers, and controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

PART I
INFORMATION REQUIRED IN THE SECTION 10(a) PROSPECTUS
The documents containing the information specified in Part I will be sent
or given to employees as specified by Rule 428(b)(1) of the Securities Act of
1933 (the "Securities Act"). In accordance with the instructions to Part I of
Form S-8, such documents will not be filed with the Securities and Exchange
Commission (the "Commission"). These documents and the documents incorporated
by reference pursuant to Item 3 of Part II of this registration statement,
taken together, constitute a prospectus that meets the requirements of Section
10(a) of the Securities Act.
PART II
INFORMATION REQUIRED IN THE REGISTRATION STATEMENT
Item 3. Incorporation of Documents by Reference.
CIENA Corporation (the "Registrant") hereby incorporates by reference into
this registration statement the following documents filed by it with the
Commission:
(a)
The Registrant's Form 10-K for the fiscal year ended October
31, 2002 and filed December 12, 2002;
(b)
All reports filed with the Commission pursuant to Section
13(a) or 15(d) of the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), since October 31, 2002, including the
Registrant's Current Reports on Form 8-K filed with the Commission
on December 12 and 20, 2002, January 10, 14 and 23, 2003; and
(c)
The description of the Registrant's Common Stock, $.01 par
value per share ("Common Stock"), contained in the Registrant's
Registration Statement on Form 8-A filed with the Commission on
January 13, 1997, including all amendments and reports filed under
Section 13(a) or 15(d) of the Exchange Act for purposes of updating
the description of Common Stock.
In addition, all documents and reports filed by the Registrant subsequent
to the date hereof pursuant to Sections 13(a), 13(c), 14, and 15(d) of the
Exchange Act, prior to the filing of a post-effective amendment to this
registration statement which indicates that all securities offered have been
sold or which deregisters all securities remaining unsold, shall be deemed to
be incorporated by reference in this registration statement and to be part
hereof from the date of filing of such documents or reports. Any statement
contained in a document incorporated or deemed to be incorporated by reference
herein shall be deemed to be modified or superseded for purposes of this
registration statement to the extent that a statement contained herein or in
any other subsequent filed document which also is or is deemed to be
incorporated by reference herein modifies or supersedes such statement. Any
such statement so modified or superseded shall not be deemed, except as so
modified or superseded, to constitute a part of this registration statement.
Item 4. Description of Securities.
Not applicable (the Common Stock is registered under Section 12(g) of the
Exchange Act).
Item 5. Interests of Named Experts and Counsel.
Not applicable.
Item 6. Indemnification of Directors and Officers.
Section 145 of the Delaware General Corporation Law permits
indemnification of officers, directors and other corporate agents under certain
circumstances and subject to certain limitations. The Registrant's Third
Amended and Restated Certificate of Incorporation and bylaws provide that the
Registrant shall indemnify its directors, officers, employees and agents to the
full extent permitted by Delaware General Corporation Law, including in
circumstances in which indemnification is otherwise discretionary under
Delaware law. In addition, the Registrant has entered into separate
indemnification agreements with its directors, officers and certain employees
which require the Registrant, among other things, to indemnify them against
certain liabilities which may arise by reason of their status or service (other
than liabilities arising from willful misconduct of a culpable nature) and to
maintain directors' and officers' liability insurance, if available on
reasonable terms. The Registrant has directors' and officers' liability
insurance with up to $100 million coverage per year. These indemnification
provisions and the indemnification agreement between the Registrant and its
officers and directors may be sufficiently broad to permit indemnification of
the Registrant's officers and directors for liabilities (including
reimbursement of expenses incurred) arising under the Securities Act.
*               *             *
Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers, and controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.
Item 7. Exemption from Registration Claimed.
Not applicable.

Item 9. Undertakings.
(a)  The undersigned Registrant hereby undertakes:
(1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this
registration statement:
(i) To include any prospectus required by Section 10(a)(3) of the
Securities Act of 1933;
(ii) To reflect in the prospectus any facts or events arising after the
effective date of the registration statement
(or the most recent post-effective
amendment thereof) which, individually or in the aggregate, represent a
fundamental change in the information set forth in the registration statement.
Notwithstanding the foregoing, any increase or decrease in volume of securities
offered (if the total dollar value of securities offered would not exceed that
which was registered) and any deviation from the low or high end of the
estimated maximum offering range may be reflected in the form of prospectus
filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the
changes in volume and price represent no more than a 20 percent change in the
maximum aggregate offering price set forth in the "Calculation of Registration
Fee" table in the effective registration statement; and
(iii) To include any material information with respect to the plan of
distribution not previously disclosed in the
registration statement or any
material change to such information in the registration statement.
Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply
if the registration statement is on
Form S-3, Form S-8 or Form F-3, and the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed with or furnished to the
Commission by the Registrant pursuant to Section 13 or Section 15(d) of the
Securities Exchange Act that are incorporated by reference in the registration
statement.
(2) That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective
amendment shall be deemed to
be a new registration statement
- 3 -
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial
bona fide
offering thereof.
(3) To remove from registration by means of a post-effective amendment any
of the securities being registered which
remain unsold at the termination of
the offering.
(b)  The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial
bona fide
offering thereof.
(c)  The undertaking concerning indemnification is set forth under the
response to Item 6.
