This Department of Defense Standard Practice is approved for use by the Defense Supply Center Columbus, Defense Logistics Agency, and is available for use by all Departments and Agencies of t
3、he Department of Defense. 2. Comments, suggestions or questions on this document should be addressed to Defense Supply Center Columbus, ATTN: VAT, Post Office Box 3990, Columbus, OH 43218-3990, or emailed to FiberOpticGroupdla.mil. Since contact information can change, you may want to verify the cur

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
5、) on military mobile vehicles 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 p
6、rocedures, test sample fabrication 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 particu
7、lar class (such as “aircraft 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, installation
8、and maintenance requirements. 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
9、user (application equipment), 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 Op
10、tical measurements. Part 2 of this standard practice addresses further details to refine or bound (constrain) the performance of each optical test measurement addressed. The test methods, such as those in a TIA-455 series standard or military standard/specification, are cited already. This part of t
11、he standard practice augments the test 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 cont
12、ractor). Part 3 Environmental, mechanical and physical measurements. Part 3 of this standard practice addresses further details to refine or bound (constrain) the performance of each environmental (including material), mechanical and physical test measurement or inspection addressed. The test method
13、s, such as those in a TIA-455 series standard or military standard/specification, are cited already. 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 tes
14、t performance. This consistency minimizes variations when comparing data obtained from different test laboratories (including commercial, vendor, Government, and Government contractor). Part 4 Test sample preparation/fabrication requirements. Part 4 of this standard practice addresses further detail
15、s to refine or bound (constrain) the preparation 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 maintainers manual, NAVAIR 01-1A-505-4/TO 1-1A-14-1, a
16、re cited already. This part of the standard practice augments the fabrication method to ensure consistency with use of the same components (such as cable types) and processes.

17、Design phase and legacy measurements. Tests that are more unique to the design phase are addressed in Part 5 of this standard practice. These test methods are provided in this part of the standard practice with the recommended replacement method. These latter test methods are listed under the constr
18、aint that they be used only with 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. Provide

SCOPE 1.1 Scope. Part 5 of this standard practice provides further details to refine or bound (constrict) the p
29、erformance of each legacy measurement addressed. 1.1.1 Applicability. Part 5 of this Standard Practice was developed to retain applicable legacy test requirements, test methods, and support processes to be used for performing testing of fiber optic components. The rapidly changing state of the art i
30、n fiber optic technology makes it essential that some degree of flexibility be exercised in enforcing this document. When there is a conflict between this document and the platform specification or contract, the platform specification or contract shall take precedence. Where obsolescence or other is
31、sues are such that the measurement requirements specified for the refinement or bound (constraint) herein cannot be implemented, users shall submit a description of the issue along with a request for clarification or with proposal for redefining the requirement to consider for incorporation into thi
32、s standard practice to: Defense Supply Center Columbus, ATTN: VAT, Post Office Box 3990, Columbus, OH 43218-3990, or emailed to FiberOpticGroupdla.mil. 1.2 Intended uses for Part 5. 1.2.1 Primary use of Part 5. Part 5 of this standard practice was prepared primarily to augment developmental testing
33、performed prior to qualification. 1.2.2 Supplemental use. Part 5 of this standard practice is intended to retain measurements or their support processes that were once cited in other parts of this standard practice, or their precursors, and are relevant to retain for legacy purposes. 1.2.2.1 Residua
34、l DOD-STD-1678 content. Part 5 addresses some test methods cited in former DOD-STD-1678. Although the test methods cited in DOD-STD-1678 are considered obsolete, a few military specifications and commercial standards still refer to some of the test methods. This residual DOD-STD-1678 content is prov
35、ided under the restrictions listed in 4.5.3.1. 1.2.3 Constraints on use. Part 5 of this standard practice is not intended to be used in lieu of a test laboratory developing test procedures specific to their test instrumentation and test equipment/apparatus.
