ECSS-Q-TM-70-51A – Termination of optical fibres (16 April 2010)


This Standard defines the technical requirements and quality assurance provisions for optical fibre terminations, fibre optic terminations, cable assemblies and installation for use in spacecraft and associated equipment. The rigorous standards set by this specification ensure the high reliability of optical fibre and fibre optic connections intended to withstand both normal terrestrial conditions and the vibrational G-loads and environment imposed by space flight.

The proper tools and equipment, correct materials, design and workmanship are covered by this Standard. Acceptance and rejection criteria are stated and some workmanship standards are included to aid discrimination between acceptable and unacceptable.

The requirements for optical fibre based sensors and health monitoring systems that require specific treatments along the optical core such as metal deposition or Bragg grating are not part of this Standard. The repair of fibre optic cables requires the development of a specific repair process procedure by the supplier that is related to the cable and its use. Repair procedures are not covered by this Standard.

This Technical Memorandum may be referred for the specific characteristics and constrains of a space project in conformance with ECSS-S-ST-00.
