Reporters obtained the following quote from the background information supplied by the inventors: "Manufacturing a mass-produced optical connector may involve quickly and permanently securing one or more optical fibers in a precise position relative to one or more lenses. Positioning the optical fibers relative to the lenses and simply applying epoxy may run the risk of applying epoxy on the ends of the optical fibers or on the lenses, which may produce a defective connector.
"The subject matter claimed herein is not limited to embodiments that solve any disadvantages or that operate only in environments such as those described above. Rather, this background is only provided to illustrate one exemplary technology area where some embodiments described herein may be practiced."
In addition to obtaining background information on this patent application, VerticalNews editors also obtained the inventors' summary information for this patent application: "Embodiments relate to systems and methods for securing an optical fiber. In particular, embodiments may relate to securing an optical fiber relative to a lens.
"This Summary introduces a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential characteristics of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.
"In an example embodiment, an optical fiber securing device may include a passage, an epoxy well, an epoxy path, an optical fiber seat, and a protrusion. The passage may have an entrance and an exit, the passage configured to receive therein an optical fiber inserted through the entrance. The epoxy well may be configured to receive therein an epoxy. The epoxy path may provide a pathway for epoxy between the epoxy well and the passage. The optical fiber seat may be configured to receive at least a portion of the optical fiber, the optical fiber seat configured to position an end of the optical fiber in optical alignment with a lens. The protrusion may define an upper boundary of the passage at the exit of the passage, the protrusion configured to restrain epoxy received within the passage such that the epoxy does not become interposed between the end of the optical fiber and the lens.
"In another example embodiment, an active cable device may include an optical cable and an optoelectronic plug. The optical cable may have opposing first and second ends and may include an optical fiber extending from the first end to the second end. The optoelectronic plug may be coupled to the first end of the optical cable, the optoelectronic plug including a lens block. The lens block may include a lens, a passage, an optical fiber seat, an epoxy well, and an epoxy path. The passage may be configured to receive therein a portion of the optical fiber. The optical fiber seat may define a lower boundary of the passage and may be configured to optically align an end of the optical fiber with the lens. The epoxy well may be configured to receive therein epoxy. The epoxy path may provide a pathway for epoxy to travel from the epoxy well to the passage.
"In another example embodiment, a method of assembling an active cable device is described. The active cable device may include an optical cable with an optical fiber and an optoelectronic plug coupled to one end of the optical cable. The method may include inserting the optical fiber of the optical cable into a passage of a lens block of the optoelectronic plug such that a portion of the optical fiber is positioned within the passage and an end of the optical fiber is positioned outside the passage. The method may also include optically aligning the end of the optical fiber with a lens of the lens block. The method may also include adding epoxy to an epoxy well of the lens block, where an epoxy path of the lens block provides a pathway for epoxy to travel from the epoxy well to the passage. The method may also include securing the optical fiber to the lens block using the epoxy.
"Additional features and advantages will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by the practice of the embodiments. The features and advantages of the embodiments will be realized and obtained by means of the instruments and combinations particularly pointed out in the claims. These and other features will become more fully apparent from the following description and claims, or may be learned by the practice of the embodiments as set forth hereinafter.
