This standard practice provides detailed information and guidance to personnel concerned with ensuring standardization of fiber optic cable topologies (optical fiber cabling and associated components) on military mobile vehicl
5、es used in air, land and sea applications. In general, the requirements and methods specified herein are not identifiable to any specific mobile vehicle class or type, but are intended to standardize and minimize variations in requirements, test setups, test measurement procedures, test sample fabri
6、cation configurations and other aspects that must be addressed for completeness. Where specified, constrains for usage or platform types will be listed. The term “platform” will be used to refer to the military mobile vehicles in general or, where designated, one particular class (such as “aircraft
7、platform”) or one particular type within that class (such as “F-35”). 4. In order to provide flexibility in the use and update of the different aspects for requirements and methods, this standard practice is issued in five parts; as follows: Part 1: Design, maintenance and installation requirements.
8、 This part addresses design requirements for platforms that use cable harnesses as the means to transport data through optical fiber among communication network and end user equipment. Larger platforms that route trunk cables through cableways and drop cables to the end user (application equipment),
9、 can cite applicable requirements in Part 1 of the Standard Practice and augment them with use of MIL-HDBK-2051 and MIL-STD-2042 as appropriate. Surface ships and submarines, are to use MIL-HDBK-2051 and MIL-STD-2042 in lieu of Part 1 of this Standard Practice. Part 2 Optical measurements. Part 2 of
10、 this standard addresses further details to refine or bound (constrain) the performance of each optical test measurement addressed. The test methods, such as those in a EIA/TIA-455 series standard or military standard/specification, are cited herein. This part of the standard practice augments the t
11、est method in the standard or specification to ensure consistency with setup and measurement procedure. This consistency minimizes variations when comparing data obtained from different test laboratories (including commercial, vendor, Government, and Government contractor). Part 3 Physical, mechanic
12、al environmental, and material measurements. Part 3 of this standard addresses further details to refine or bound (constrain) the performance of each physical, mechanical, environmental and material test measurement or inspection addressed. The test methods, such as those in a TIA-455 series standar
13、d or military standard/specification, are cited herein. This part of the standard practice augments the test method to ensure consistency with setup, measurement procedure, data recording/analysis and other factors critical to conducting or evaluating test performance. This consistency minimizes var
14、iations when comparing data obtained from different test laboratories (including commercial, vendor, Government, and Government contractor). Part 4 Test sample configuration and fabrication requirements. Part 4 of this standard addresses further details to refine or bound (constrain) the configurati
15、on and fabrication of test samples for the fiber optic components addressed. Fabrication methods, such as those in the Shipboard installation standard, MIL-STD-2042, or in the general series aircraft maintenance manual, NAVAIR 01-1A-505-4/T.O. 1-1A-14-4/TM 1-1500-323-24-4, are cited herein. This par
16、t of the standard practice augments the fabrication method to ensure consistency with use of the same components (such as cable types) and processes and augments the component specification to ensure consistency of the test sample configuration.

Tests that are more unique to the design phase or tests and inspections that are not just primarily for qualification (supplemental measurements) are addressed in Part 5 of this standard prac
18、tice. Also, legacy test methods and legacy criteria measurements are provided in this part of the standard practice with the recommended replacement method for the former (legacy) DOD-STD-1678 methods. These former DOD-STD-1678 test methods are listed under the constraint that they be used only with
19、 the specific military specifications or commercial standards in which they are cited. The intent is to delete each DOD-STD-1678 test method from that standard practice in Part 5 once its reference from military specification or commercial standard is removed. Part 6 Parts and support equipment comm
20、onality and standardization requirements, cable harness configurations. This part of the Standard Practice addresses component part and support equipment standardization requirements for platforms that use cable harnesses as the means to transport data through optical fiber among communication netwo
21、rk and end user equipment. Surface ships and submarines are to use the Navy Shipboard Fiber Optic Recommended Components Parts List (a copy may be found at web site: https:/fiberoptics.nswc.navy.mil/) in lieu of part 6 of this Standard Practice. Likewise, larger platforms that route trunk cables thr
22、ough cableways and drop cables to the end user (application equipment), can cite applicable requirements in Part 6 of the Standard Practice, cite the Navy shipboard Fiber Optic Recommended Components Parts List, or both, as appropriate.

34、 SCOPE 1.1 Scope. Part 3 of this standard practice provides further details to refine or bound (constrict) the performance of each physical, mechanical, environmental, and material test measurement addressed. 1.1.1 Applicability. The test methods, such as those in the TIA/EIA-455 series standard or
35、military standard/specification, are cited already. This part of the standard practice augments the test methods in the TIA/EIA-455 series standard or military standard/specification to ensure consistency with setup and measurement procedure. This consistency minimizes variations when comparing data
36、 obtained from different test laboratories (including commercial, vendor, Government, and Government contractor). The rapidly changing state of the art in fiber optic technology makes it essential that some degree of flexibility be exercised in enforcing this document. When there is a conflict betwe
37、en this document and the platform specification or contract, the platform specification or contract will take precedence. Where obsolescence or other issues are such that the measurement requirements specified for the refinement or bound (constraint) herein cannot be implemented, users will submit a
38、 description of the issue along with a request for clarification or with proposal for redefining the requirement to consider for incorporation into this standard practice to: DLA Land and Maritime, ATTN: VAT, Post Office Box 3990, Columbus, OH 43218-3990, or emailed to FiberOpticGroupdla.mil. 1.2 In
39、tended uses for Part 3. 1.2.1 Primary uses of Part 3. Part 3 of this standard practice was prepared primarily for qualification functions performed by Government Personnel (including Government contractors acting on behalf of the Government) as specified in 1.2.1.1 through 1.2.1.3 1.2.1.1 Auditing.
40、Use for performing audits of test laboratories doing testing for fiber optic cable topology (FOCT) components. 1.2.1.2 Test procedure review. Use to review physical, mechanical, environmental, and material test procedures for a FOCT component. 1.2.1.3 Test report review. Use to review the physical,
41、mechanical, environmental, and material testing performance as part of a test report for a FOCT component. 1.2.2 Supplemental use. Part 3 of this standard practice is intended to identify to vendors and test laboratories the areas of emphasis for Government review for physical, mechanical, environme
42、ntal, and material test measurements performed as part of a FOCT component qualification process. 1.2.3 Use for content. Each physical, mechanical, environmental, and material measurement augments the test methodology and performance requirements in a narrative format to the extent deemed necessary
43、for that measurement. Checklists may be included that contain primary requirements in a table format. When a checklist is included, further clarification of the items in the table can be found in applicable physical, mechanical, environmental, or material measurement. 1.2.4 Constraints on use. a. Co
44、mmercial entities are expected to be familiar with the test standards cited by the Government for use. Part 3 of this standard practice does provide some guidance and clarifications for successful implementation within the test standards cited. b. Part 3 of this standard practice is not intended to
45、be used in lieu of a test laboratory developing physical, mechanical, environmental, and material test procedures specific to the fiber optic component military specification.
