Problems solved by technology

However, such plug connectors do not employ multiple ferrules and as a result the coupling of light into and out of a fiber in an MT-RJ or other multi-fiber single ferrule connector can not be independently optimized for each fiber.
Therefore, optical plug connectors which do not incorporate a single ferrule for a single optical fiber introduce new problems, and, as such, optical plug connectors which do not incorporate a single ferrule in conjunction with a single optical fiber are not further considered.

Embodiment Construction

[0040] Referring now to the drawings, wherein like reference numerals designate identical or corresponding parts throughout the several views, and more particularly to FIGS. 2-5 and 8-23 thereof, is an optical plug 10, 30, 60, 80, 100, 120.

[0041] FIG. 2 is a perspective view of the plug 10 which shows four ferrules 12 held by a body 8. The body 8 is made of a polymer material and is typically formed by an injection molding process. The ferrules 12 are preferably made of a glass, a ceramic material, or a polymer material. Each ferrule 12 has a portion which conforms to the LC standard and, as such, has a nominal diameter of 1.25 mm and an aperture extending along the length of the ferrule 12 so as to receive an optical fiber. FIG. 3 is a top view of the plug 10. FIG. 4 is a side view of the plug 10 showing the ferrules 12, where the ferrules 12 are positioned substantially in a single plane. FIG. 5 is a bottom view of the plug 10 which shows the center-to-center spacing, W, between f...

Abstract

A fiber optic plug for connecting to a receptacle of a small format optoelectronic package or device. The fiber optic plug includes a body and ferrules attached to the body. Each ferrule has an aperture for receiving and holding an optical fiber and each ferrule has a diameter substantially equal to 1.25 mm. The aperture of each adjacent ferrule is separated by a distance of approximately 3.125 mm. The ferrules exist in a plane.

Description

[0001] 1. Field of the Invention[0002] The present invention pertains to fiber optic connectors for optoelectronic devices or optical subassemblies. The invention more particularly concerns a fiber optic plug for connecting to a receptacle of a small format optoelectronic package such as a modular high density multiple optical transmitter / receiver array.[0003] 2. Discussion of the Background[0004] Optoelectronic devices such as optical transceivers are known in the art and include active optical devices or diode packages. One such optoelectronic device is a removable optoelectronic module as described in U.S. Pat. No. 5,546,28, which is hereby incorporated herein by reference. One end of the removable optoelectronic module includes two SC style ports or receptacles forming an SC duplex receptacle for receiving SC style ferrules. Often, the two SC style ferrules are either ganged together or are assembled in a common plug body so as to form an SC duplex plug. The ferrule of an SC plu...
