The wide extensions occupied by the new last-generation radiotelescopes (formed by arrayed antennas) made necessary the distribution of synchronism signals between different antennas, assuring his functionality as a whole. In some cases, these harnessing distributions can get 15km. The transmitted high frequencies and the high stability requirements of the signals have caused the rejection of electrical harnessing, which would be even more expensive.
The transport of the synchronism signal through optical fiber is the only method currently used in the great developed radiotelescopes, assuring their functionalities with the maximum guarantee regarding phase-stability, transmission losses or high-frequency signal transportation, among others.
DAS Photonics has a great experience in developing optical harnesses to distribute synchronism signals in outdoor environments, assuring the most demanding performances and allowing a mass and volume reduction, in comparison with its electrical counterpart.
Some of the most remarkable characteristics of the harnesses developed by DAS are:
- Harnesses with SM, MM and PM fibers, single or mixed
- Ruggedized cables for severe outdoor and indoor environments
- Use of simple or multipolar connectors, following MIL-DTL-XXX military standards
