A mechanical splice is indeed a method of joining two fiber optic cables using an alignment fixture or a mechanical connector. This technique allows the two fiber ends to be aligned precisely, enabling the light signals to pass through with minimal loss. The alignment fixture holds the fibers together at their ends, and an adhesive or index-matching gel can be used to reduce any air gaps that might cause signal loss.

This method is particularly useful when a permanent fusion splice is not feasible or desirable, as it allows for the temporary connection of fibers and can be easily reconfigured or adjusted. The clarity of this definition aligns with the function of mechanical splices in ensuring effective signal transmission through fiber optic networks.
