Ain't no such critter, c is c is c, to paraphrase Gertrude Stein (or was it GB Shaw?) You may be thinking of high frequency, short wavelengths?

Short wavelengths do allow smaller spot sizes for diffraction-limited optics, and can support higher frequency modulation- *but* UV does not propagate through any optical materials well enough to be used in fiber transmission. The lowest losses are in the near IR at around 1100 to 1500 nm, and IR transmission is used exclusively despite visible light diode lasers being available.

Blue lasers based on gallium nitride are bleeding-edge tech even nowUV lasers will be even more painful.
