“…The advantages inherent in using longer wavelength fiber optic links in a spacecraft with a high radiation requirement, as in the proposed Europa mission (greater than 1 Megarad(Si)), are further emphasized by the data in Figure 3 [6] for single mode fibers Co-60 irradiated at 22 rads at room difference in the induced attenuation at 10 krads between 850 nm and 1550 nm. Thus, from the point of view of radiation hardness, longer operating wavelengths are more desirable unless for some reason, the fiber must contain phosphorus.…”

Ken .label @ g sfc.nasa.gov (301) 286-9936Abstruct-As civilian and military spacecraft continue to evolve, meeting performance demands will become particularly challenging because performance levels will be constrained by severe cost and weight restrictions. To meet these challenges, new technologies, such as photonics, w i l l be employed that can provide desired performance levels within the framework dictated by these constraints. For the insertion of a new technology into a spacecraft to be successful, the radiation hardness assurance (RHA) of the technology must be established so that the mission is not jeopardized by exposure to the space radiation environment. In this paper we discuss the RHA issues associated with the infusion of photonics into space systems, both military and civilian. These issues w i l l be contrasted with similar problems that have been encountered in the more traditional area of RHA for Si microcircuits.
