An optical termination element for terminating an optical fiber carrying a
signal of first maximum power level comprises a termination fiber which is
unable to propagate a fiber fuse when the signal power is below a
threshold power level which is greater than the first maximum power level.
The termination fiber is designed by selecting values of the core diameter
and the higher mode cutoff wavelength. The intention provides a
termination component in which a fiber fuse can not be initiated at the
maximum power to be provided to the termination.
