When using the LaTeX package url (\usepackage{url} somewhere in the preamble) which tends to give much more nicely formatted web addresses, the following may be preferred:

 @misc{ wiki:xxx,
   author = "Fixme.ch",
   title = "Free Space Optics --- Fixme.ch{,} ",
   year = "2019",
   url = "\url{https://fixme.ch/w/index.php?title=Free_Space_Optics&oldid=5618}",
   note = "[Online; accessed 6-January-2026]"
