Gould Fiber Optics has developed a glass solder process (US Patent numbers 5,500,917 and 5,682,453) for making a glass to glass bond between optical fibers and silica substrate. The patented technique produces a uniform “solder” bead that affixes the fiber to the substrate to provide exceptional mechanical and environmental stability. This bond is much stronger than epoxy and is not susceptible to degradation from humidity. The significance of this packaging improvement is evident in High Temperature Oil & Gas Down-Hole and outside plant applications where long term reliability requirements are stringent.
