Abstract:
A launch fiber termination including in combination:a quartz or silica ferrule having a bore therethrough with at least a portion having a first predetermined diameter;an optical fiber having a silica core and a polymer external jacket, the jacket being stripped from a predetermined length of an end of the optical fiber to expose a portion of the silica core which is placed in the bore of the quartz ferrule, with at least the portion of the exposed silica core in the bore of the ferrule being heat fused to the portion of the bore of said first predetermined diameter to bond the ferrule and the silica core of the optical fiber together; anda beam block located adjacent the entry end of the quartz ferrule and bonded to it, with the beam block including an extension having a length sufficient to extend over the external jacket of the optical fiber when the predetermined length of exposed silica core is placed in the bore of the quartz ferrule, and wherein the extension of the beam block is secured to the external jacket of the optical fiber by mechanical crimping.
