Loss Budget Specification for Fiber Optic Links
This document defines a quantified means of specifying a digital fiber optic link loss budget:
- Between end users and system integrators
- Between system integrators and subsystem suppliers
- Between subsystem suppliers and component vendors
The standard specifies methods and the margin required for categories of links.
Rationale: The aerospace industry requires precise standards for avionics system design. To ensure that the aerospace fiber optics industry also adopts these same high standards, it is essential that a common set of fiber optic system design procedures be established. This document outlines procedures needed for digital avionics fiber optic link system design that help to assure it complies with aerospace industry best practices.
It also provides an easily specified document for use during a complex system acquisition referencing back to the previously approved standard AS5603 for the detailed calculations.
