发明名称 Dual inner diameter ferrule device and method
摘要 A fiber optic ferrule includes a body extending from a first end to a second opposite end, with the body including an axial passage extending between the first and second ends. The axial passage includes a first diameter portion having a diameter of at least 125 microns, and a second diameter portion having a diameter of at least 250 microns and less than a diameter of the buffer, the second diameter portion positioned between the first diameter and the second end. The axial passage further defines a tapered shape at the second end extending inward from the second end to the second diameter portion. A hub holds the ferrule. A method of assembling a terminated fiber optic cable is also provided.

主权项 1. A fiber optic ferrule and cable, the fiber optic ferrule terminating the cable, the fiber optic ferrule and cable comprising: an optical fiber cable including an inner fiber, an outer coating, and a buffer layer, the outer coating positioned around the inner fiber and the buffer layer positioned around the outer coating, a portion of the outer coating and inner fiber extending beyond an end of the buffer layer and a portion of the inner fiber extending beyond an end of the outer coating; a ferrule body extending from a first end to an opposite second end, the ferrule body including an axial passage extending between the first and the second ends of the ferrule body, the axial passage of the ferrule body including: a first portion extending from a first end to an opposite second end, the first end of the first portion adjoining the first end of the ferrule body, the first portion defining a first internal cylinder closely surrounding the inner fiber from the first end to the second end of the first portion;a second portion extending from a first end to an opposite second end, the second portion positioned between the first portion and the second end of the ferrule body, the second portion defining a second internal cylinder from the first end to the second end of the second portion; anda transition portion extending from a first end to an opposite second end, the first end of the transition portion continuing from the second end of the first portion and the first end of the second portion continuing from the second end of the transition portion, and a diameter of the transition portion continuously increasing from the first end to the second end of the transition portion; a hub fixedly mounted around the second end of the ferrule body, the hub including an axial passage; and an adhesive material within the axial passage of the ferrule body fixedly holding the inner fiber of the optical fiber cable to the ferrule body; wherein the first portion of the axial passage receives the inner fiber; wherein the second portion of the axial passage receives the outer coating; wherein the end of the buffer layer is positioned in the axial passage of the hub; wherein the end of the outer coating is spaced a first distance away from the transition portion when the adhesive material fixedly holds the inner fiber of the optical fiber cable to the ferrule body; and wherein the end of the buffer layer is spaced a second distance away from the transition portion when the adhesive material fixedly holds the inner fiber of the optical fiber cable to the ferrule body, the second distance being greater than the first distance.
