摘要： Ferrules having at least one tapered fiber channel that supports at least one optical fiber are disclosed. The at least one tapered fiber channel is defined by at least one channel wall. The material making up the channel wall is at least one of deformable and removable by forcible contact by the at least one optical fiber when the optical fiber is inserted into the fiber channel. This results in the formation of an interference fit between the front channel end and the optical fiber end when the diameter of the optical fiber end exceeds the diameter of the channel front end. The fiber channel wall may optionally include at least one deformable and/or removable-by-contact protrusion, with the at least one protrusion preferably being located in the channel section adjacent the narrow front channel end. Methods of forming the ferrules are also disclosed. Single-fiber and multi-fiber optical fiber connectors that employ the ferrules are also disclosed.

摘要： A guide block assembly and associated method are provided for retaining a plurality of fiber bore forming pins and at least one guide bore forming pin in precise relation to each other during molding of a multi-fiber ferrule used in a multi-fiber connector. The assembly comprises an array of fiber bore blocks each with a fiber bore therethrough to retain a respective one of the fiber bore forming pins. At least one guide block that defines a guide bore for retaining a guide bore forming pin is assembled with the array of fiber bore blocks. Adjoining surfaces are defined between adjacent fiber bore blocks and between the guide bore blocks and the array of fiber bore blocks. The use of bores more precisely retains the pins during the molding process, and the use of blocks with adjoining surfaces allows for the machining of such surfaces to precisely establish the relationships between successive fiber bore blocks and between the array of fiber bore blocks and the guide bore blocks.

摘要： A guide block assembly for aligning and retaining fiber bore forming pins and guide pin bore fanning pins in precise relation to each other during the molding of a multi-fiber ferrule includes a unitary member defining at least one fiber bore and at least one guide pin bore. Each fiber bore, and optionally each guide pin bore, is formed by creating a starter hole using a first electric discharge machining (EDM) wire and enlarging the starter hale using a second EDM wire. Each fiber bore has a length to diameter ratio of between approximately 3::1 to 10::1, more preferably between approximately 4::1 to 8::1, and most preferably approximately 6::1. The guide block assembly may further include a cavity behind the fiber bore and a front face that forms a non-rectilinear surface on the face of the female. The unitary block assembly contains fewer parts and is less expensive to manufacture.

The multi-fiber ferrule includes an optical fiber receiving portion, a lead-in portion, and an alignment portion. The alignment portion includes a buffered fiber alignment portion to orient and separate buffered optical fibers. The alignment portion may also include a ribbon alignment portion to orient and align the optical fibers of an optical fiber ribbon.

摘要： A ferrule is provided that has an exterior surface that can be defined with sufficient precision to serve as a datum during subsequent polishing operations. The ferrule includes first and second ferrule body portions that are joined along a parting line. The first ferrule body portion has a first width and the second ferrule body portion has a second width that is less than the first width, such as by at least 50 microns. In addition, the width of the first ferrule body portion is defined to be within a first tolerance, while the width of the second ferrule body is defined to be within a second tolerance that is larger than the first tolerance. As such, the first ferrule body portion is not only larger than the second ferrule body portion, but the first ferrule body portion is also more precisely defined. Thus, only one portion of the ferrule of the present invention needs to be precisely defined. A mold for forming the ferrule and a method of fabricating the ferrule are also provided.
摘要翻译：提供了一种套圈，其具有外表面，该外表面可以以足够的精度限定，以在随后的抛光操作期间用作基准。套圈包括沿分型线连接的第一和第二套圈主体部分。第一套圈主体部分具有第一宽度，并且第二套圈主体部分具有小于第一宽度的第二宽度，例如至少50微米。此外，第一套圈主体部分的宽度被限定在第一公差内，而第二套圈主体的宽度被限定在大于第一公差的第二公差内。因此，第一套圈主体部不仅大于第二套圈本体部，而且也更精确地限定第一套圈主体部。因此，仅需要精确地限定本发明的套圈的一部分。还提供了用于形成套圈的模具和制造套圈的方法。

摘要： A precision mold insert and method for manufacturing angled or angled and bumpered multi-fiber ferrules. The precision mold insert includes an angled end face forming portion, one or more optional bumper forming portions, one or more fiber bores for receiving one or more fiber bore forming pins, and one or more guide pin holes for receiving one or more guide pin hole forming pins. A method for manufacturing a precision mold insert for molding angled or angled and bumpered multi-fiber ferrules utilizing electrical discharge machining (EDM) process and/or a poly crystalline diamond (PCD) grinding tool is provided. The mold insert is used to produce a multi-fiber ferrule having a pre-molded angled end face that is not machined, polished or otherwise altered subsequent to the molding process. The ferrule may also include bumpers for polishing end portions of optical fibers positioned within the fiber bores without altering the angled end face.
