Low cost Fiber Optic Connectors

Connectors can be quickly attached to optical fibers using two adhesive and a modified ferrule design.

Conventional ""quick attach'' connectors grip and center the fiber with a precision mechanical chuck. In a cheaper, but more time consuming, connector assembly method the optical fiber 10 is inserted into opening 11 in the ferrule 12, as shown in Fig. 1. An epoxy adhesive 14 facilitates the insertion of the fiber into the ferrule, serving as an initial lubricant, and after several hours of curing time, secures the fiber.

The fiber-to-ferrule bond can be hastened using the modified ferrules 16 and 18 shown in Figs. 2 and 3, respectively. The fiber 10 is inserted into a central hole 11 through the ferrule, as before, using an epoxy adhesive 14 as a lubricant for ease of insertion. Immediately after insertion of the fiber, a solvent is used to remove the uncured epoxy 14 from the recesses 20 of the ferrule 16 (Fig. 2) or from the adhesive insertion hole 22 of the ferrule 18 (Fig. 3). A quick curing cyanoacrylate adhesive is then applied to these areas to provide an immediate bond.
