This handbook has been prepared to support the applications of
MIL-STD-1773 systems. It has been written to promote good design
procedures and provide technical guidance for implementing,
installing, and maintaining a MIL-STD-1773 system.
To meet MIL-STD-1773 Users' needs, the following topics are
covered in the handbooks chapters:
Chapter 3. Media Design.
○ Parameters that must be specified to make bus terminals
interoperable.
○ Various topology choices.
○ System performance criteria such as Optical Power Budget
bit error rate (BER), and dynamic range.
○ Describes how 1773 fiber optic systems may be integrated
into electrical 1553 systems to produce a hybrid system.
Chapter 1. Background.
○ A short history of the development of fiber optic
technology and an overview of MIL-STD-1773.
Chapter 2. Components for Media Implementation.
○ Brief descriptions of components that may be used
in MIL-STD-1773 bus media implementation.
○ Relevant properties and features that should be
considered to optimize a design for its intended purpose.
○ Technical issues and available options are discussed.
Chapter 4. Electrical/Optical Interface Considerations.
○ Basic elements of fiber optic transmitter and receiver
design.
○ Descriptions of active components.
○ Tests that measure circuit performance.
Chapter 5. Environmental and Performance Testing.
○ Table of environmental and performance tests compiled
from military standards and Fiber Optic Test Procedures
(FOTPs). These standards and FOTPs have been listed to
show the MIL-STD-1773 system user and designer the types
of adverse environments and conditions which the overall
system and fiber optic components roust withstand.
Chapter 6. Testing and Diagnostics.
○ Measurement methods that establish system performance
limits.
○ Troubleshooting methods.
Chapter 7. Media Installation Considerations.
○ Fiber Cable Assembly and Installation Considerations.
○ Lessons learned on the AV8B Harrier program.
○ Lessons learned during installation of a Fiber Optic
position sensing system on a commercial aircraft.
Chapter 8. Radiation Effects.
○ Provides pointers on the application of MIL-STD-1773 in a
nuclear radiation environment.
○ Overviews the effect of radiation on individual
components.
Chapter 9. Terms and Definitions.
○ Definition of terms important to MIL-STD-1773.
References.
○ Bibliography. The bibliography gives references used to
compile the information given in this documents

Fibers in Avionic Platforms.
○ A discussion of the fiber quality issues and installation
parameters which affect the service life of fibers most
likely to be used in Avionics applications.
