ABSTRACT:
An insert (21) is molded within an optical fiber connector (2,3) to provide more precisely defined and symmetric alignment surfaces (5,6). The insert may be used for connectors directly molded about an optical fiber or for field mountable connectors subsequently affixed thereto. During molding, the insert partitions the mold cavity into two portions. The first portion (53) defines the alignment surfaces and the second defines the balance of the connector. Filler material (55) fills the second portion first and then is conducted through the insert to symmetrically fill the first portion. This directed flow control also precludes bending of the optical fiber (32) during direct molding of a connector about the fiber.
