AMERICAN NATIONAL STANDARD
Approval of an American National Standard requires verification by ANSI that the requirements for due
process, consensus, and other criteria for approval have been met by the standards developer.
Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial
agreement has been reached by directly and materially affected interests. Substantial agreement means
much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and
objections be considered, and that a concerted effort be made toward their resolution.
The use of American National Standards is completely voluntary; their existence does not in any respect
preclude anyone, whether he has approved the standards or not, from manufacturing, marketing,
purchasing, or using products, processes, or procedures not conforming to the standards.
The American National Standards Institute does not develop standards and will in no circumstances give
an interpretation of any American National Standard. Moreover, no person shall have the right or
authority to issue an interpretation of an American National Standard in the name of the American
National Standard Institute. Requests for interpretations should be addressed to the secretariat or
sponsor whose name appears on the title page of this standard.
CAUTION NOTICE: This American National Standard may be revised or withdrawn at any time. The
procedures of the American National Standards Institute require that action be taken periodically to
reaffirm, revise, or withdraw this standard. Purchases of American National Standards may receive
current information on all standard by calling or writing the American National Standards Institute.
NOTE: The user’s attention is called to the possibility that compliance with this standard may require use
of an invention covered by patent rights.
By publication of this standard, no position is taken with respect to the validity of this claim or of any
patent rights in connection therewith. The patent holder has, however, filed a statement of willingness to
grant a license under these rights on reasonable and nondiscriminatory terms and conditions to
applicants desiring to obtain such a license. Details may be obtained from the standards developer.

Introduction
1
The VITA 66 base standard defines physical features of a stand-alone compliant blind mate Optical
Interconnect for use in VPX systems. This standard does not apply to monolithic VPX connectors such
as, but not limited to, [VITA 60] or [VITA 64].
1.1 Objectives
The objectives of this standard are:
Define a suitable family of optical interconnects for use on [VITA 46.0] plug-in modules and
backplanes
1.2 Terminology
1.2.1 Specification Key Words
To avoid confusion and to make very clear what the requirements for compliance are, many of the
paragraphs in this standard are labeled with keywords that indicate the type of information they contain.
These keywords are listed below:
Rule
Recommendation
Suggestion
Permission
Observation
Any text not labeled with one of these keywords is to be interpreted as descriptive in nature. These will be
written in either a descriptive or a narrative style.
The keywords are used as follows:
Rule -:
Rule 1.2.1-1: Rules form the basic framework of this standard. They are sometimes expressed in
text form and sometimes in the form of figures, tables or drawings. All rules shall be followed to
ensure compatibility between board and backplane designs. All rules use the “shall” or “shall not”
words to emphasize the importance of the rule. The “shall” or “shall not” words are reserved
exclusively for stating rules in this standard and are not used for any other purpose.
Recommendation -:
Recommendation 1.2.1-1: Wherever a recommendation appears, designers would be wise to take
the advice given. Doing otherwise might result in poor performance or awkward problems.
Recommendations found in this standard are based on experience and are provided to designers to
speed their traversal of the learning curve. All recommendations use the “should” or “should not”
words to emphasize the importance of the recommendation. The “should” or “should not” words
are reserved exclusively for stating recommendations in this standard and are not used for any other
purpose.
Suggestion -:
Suggestion 1.2.1-1: A suggestion contains advice, which is helpful but not vital. The reader is
encouraged to consider the advice before discarding it. Some design decisions that need to be made
are difficult until experience has been gained. Suggestions are included to help a designer who has
not yet gained this experience.

Permission -:
Permission 1.2.1-1: In some cases a rule does not specifically prohibit a certain design approach,
but the reader might be left wondering whether that approach might violate the spirit of the rule or
whether it might lead to some subtle problem. Permissions reassure the reader that a certain
approach is acceptable and will cause no problems. All permissions use the “may” word to
emphasize the importance of the permission. The lower-case “may” word are reserved exclusively
for stating permissions in this standard and are not used for any other purpose.
Observation -:
Observation 1.2.1-1: Observations do not offer any specific advice. They usually follow naturally
from what has just been discussed. They spell out the implications of certain rules and bring
attention to things that might otherwise be overlooked. They also give the rationale behind certain
rules so that the reader understands why the rule must be followed.
1.2.2 Definitions
The following terms are used within the body of the specification. In this context, they have the following
meanings.
Table 1.2.2-1: Term Definitions
Term
Definition
Compliance
Conformity in fulfilling Official Requirements.
Compatibility
Conformity
Connector
Full-width
Optical Terminus
Interoperability
Half-width
Module
The ability of an item not meeting all requirements of compliance to
interoperate with compliant items albeit with less capability.
The act of Verifying the item's performance against each declared
requirement.
A mechanical device used to hold two parts of an electrical or optical
circuit together.
In the context of this standard, Full-width is defined as the width of a
[VITA 46.0] electrical connector block occupying a J1/P1 through J6/P6
(6U) or J2/P2 (3U) position on the backplane or module.
A specific element in an optical connector that couples a functional signal
between the two mating halves.
The ability of two items that is compliant or compatible to the same sets of
requirements to function together.
In the context of this standard, Half-width is defined as one half of the
width of a [VITA 46.0] electrical connector block occupying a J1/P1
through J6/P6 (6U) or J2/P2 (3U) position on the backplane or module.
A printed wire assembly which conforms to defined mechanical and
electrical specifications.
MT or MT Ferrule
MT or MT Ferrule is a rectangular optical component with a typical 2,5mm
by 6,4mm mating face and contains multiple fiber positions.
Official Requirements
Those declared by this specification and any referenced specifications
and standards.

PWB
Verification
Printed Wiring Board. A component of a Module containing the
interconnecting printed copper traces and on which electronic
components are soldered.
Verification is accomplished by one or more of several accepted methods:
Inspection, Demonstration, Analysis, Test.
1.3 Normative References
The publications listed in this Section are referenced by this standard. Unless otherwise noted the use of
the latest revision is assumed.
The following standards are available from the VMEbus International Trade Association (VITA).

2 Compliance
2.1 Statement of Compliance
Any product claiming compliance to this specification must provide, on request, a statement of
compliance which clearly indicates the following:
The specific revision of the specification,
Rules plus verification outcome (Pass/Fail),
The state of recommendations and permissions (implemented/did not implement), and verification
outcome (Pass/Fail).
In the event of a dispute arising between a product’s performance to the specification and the claim of
compliance, a user may request evidence of conformity for only those requirements in dispute. The
evidence of conformity may contain intellectual property or industrial secrets of a highly proprietary
nature, and therefore it is recommended that any user, before executing a request of this nature, verify
both Non-Disclosure Agreements, and any contractual restrictions that may exist.
Rule 2.1-1: For any product claiming compliance to this specification the supplier shall provide, on
request, a Statement of Compliance.
Observation 2.1-1: Future work might include an example of a Statement of Compliance included in
an appendix.
2.1.1 Compatibility
Items claiming compatibility will have the characteristic of Interoperability, albeit with less functionality. A
specific example is fewer fibers on the module side than available on the backplane side, thus limiting the
number of optical channels that may be supported, but in all other respect fully compliant with the mating
interface.
2.2 Verification Method Notation
At the end of each Rule and Recommendation the verification method is specified and denoted as
follows:
[VM = vmlist]
Where:
VM = Verification Method,
vmlist = Verification Method List
The Verification Method List consists of one or more of the following: I (Inspection), D (Demonstration), A
(Analysis), T (Test), VNR (Verification Not Required), and are listed in the recommended order. For
example:
[VM = I] means Inspection only
[VM = D,A,T] means Demonstration is recommended, Analysis and Test are permitted
[VM = T,D] means Test is recommended, Demonstration is permitted
[VM = VNR] means Verification Not Required.
Each of the four methods of verification are described in section 2.3
