Abstract

The use of a multi-termini optical connector has been adopted on two GSFC programs. This connector system introduces the use of individually removable, specially polished, physically touching, optical contacts. This evaluation addresses performance of the Amphenol-Bendix "453" connector using optical contacts in a random vibration environment. The results show that this multi-termini connector performs within the manufacturer's specifications to at least 37 Grms random vibration, with thermal cycling preconditioning. Contamination was found to be generated by the connector itself, indicating the need for attention to cleanliness and the development of adequate cleaning procedures. Alignment sleeve retention force played a role in the occurrence of metal filing contamination between one of the optical contact pairs, indicating that alignment sleeve retention force should be more closely controlled. Finally, the optical contacts with less than ideal polish qualities tended to degrade over the duration of the evaluation which indicates that cleave and polish damage can lead to increased polish surface defects over the life of the optical connector. While the "453" connector was found suitable for use in environments that experience mild thermal cycling, further study of the relationship between the surface polish defects, temperature and fiber tension will show their suitability for use in more thermally stressful environments.
