An environmentally sealed electronics assembly. The assembly includes a flexible envelope surrounding the active electronics board. The electronics board is insertable into the envelope and with subsequent sealing provides a reenterable but environmentally sealed active electronics package. Methods of manufacturing the assembly are also described.

An optical fiber water sensor includes a mandrel having a convex or concave shape adjacent to an optical fiber which is adjacent to a water swellable material held in a reservoir. Upon coming in contact with water, the material swells and deforms a section of the optical fiber about a contour defined by the mandrel thus attenuating a signal propagating through the fiber which is detected by an optical detector to indicate the presence of water.
