Handling
Being extremely thin, an SDF is also extremely fragile. Therefore, an SDF is usually mounted onto a special frame immediately after pulling and is never detached from this frame.
Another issue is dust particles which may adsorb to the surface of an SDF. If significant laser power is coupled into the fibre, dust particles will scatter light in the evanescent field, heat up and may thermally destroy the waist. In order to prevent this, SDF are pulled and used in dust-free environments such as flowboxes or vacuum chambers.

Famous quotes containing the word handling:
“It is curious how instinctively one protects the image of oneself from idolatry or any other handling that could make it ridiculous, or too unlike the original to be believed any longer.”
—Virginia Woolf (1882–1941)
“For a novel addressed by a man to men and women of full age; which attempts to deal unaffectedly with the fret and fever, derision and disaster, that may press in the wake of the strongest passion known to humanity; to tell, without a mincing of words, of a deadly war waged between flesh and spirit; and to point the tragedy of unfulfilled aims, I am not aware that there is anything in the handling to which exception can be taken.”
—Thomas Hardy (1840–1928)
“That a good fit between parental handling and child temperament is vital to help children adapt to the imperatives of their society is a crucial concept that can be applied to other cultures.”
—Stella Chess (20th century)
