Image of a bubble at the fusion splice between two ordinary multimode fiber optics. This bubble causes extreme fiber optics splicing high loss as shown visually via Visual Fault Locator (VFL) on the right hand side image.
This bubble resulted from dirt on the fiber end surface. Proper care should be taken care of during cleaning process of fiber optics by using appropriate cleaning device such as isoprophyl alcohol. It is better to redo the splicing immediately so as to obtain minimum splicing loss possible.

I have noticed that Fujikura 50S and 60s seem to have more bubbles whereas i never get them on the 30S. I notice that the 30S always has a constant timed , huge arc that hides the entire video screen. Does this giant arc clear/burn away the dirt on the fiber ends resulting in such perfect splices?

AuthorI have been in the field of fiber optics since early 1990s. I gained fiber optics skills and knowledge via my working experience as end-user, main contractor and sub-contractor and finally as an optical fiber enterpreneur. Archives
