17 February 2010 Comparison of small fiber connectors for high-power transmission
Author Affiliations +
Small fibre connectors capable of handling medium powered lasers are available on the market from multiple suppliers. Typical connector types are the SMA905 and LD80. The capability to handle power losses, for example radiation falling outside the fibre core is, due to the small size and restrictive design, limited. A new type of SMA fibre connector, designed for high-power loss capability will be presented. The basic principle is to strip off the losses in terms of radiation rather than being absorbed in the fibre connector. The radiation is instead absorbed in the female connector housing or within the laser housing, where it can easily be cooled away. In this paper both the principles and measurement of power capability are presented. Furthermore, in order to give a perspective of the available high-power SMA fibre connectors on the market today, a comparison between the best competitive products is presented.
