US Classification:

707/500000, 707/907000

Abstract:

A file is separated into three sections: a root, one or more fragments, and a fragment index. The root, which is uncompressed, maintains relationship information regarding fragments within the file. The fragments contain the actual data and are compressed, and the index, which is uncompressed, provides a list of all the fragments and, for example, an identification of any attributes associated with those fragments. Using this nomenclature, selective compression and decompression documents is possible.

Abstract:

A housing for fiber optic components reduces stress on optical fibers and protects the components from environmental shock and vibration. The housing includes a protective body having a receiving space wherein the fiber optic component is positioned. A rigid adhesive applied to the fibers in a specific stress reducing profile near the ends of the receiving space secures the component out of contact with the wall of the receiving space without inducing stress on the jacketless optical fibers. A gel support material fills the receiving space surrounding the component and providing vibration isolation. The invention is particularly uses for housing fiber optic couplers which are subject to shock, vibration, and temperature extremes.
