Abstract
Abstract A device for splicing multiple optical fibers includes a splice element having means for holding the optical fibers, a splice body having a slot containing the splice element, and extensions on either end of the splice body for supporting a portion of the fibers. Each of the extensions has an end cover positionable in open and closed positions which provides protection to the fibers against environmental influences. The end covers may advantageously include collapsible compartments filled with a sealant material whereby, when the covers are moved to the closed positions, the sealant material is channeled towards the slot containing the splice element.
