Patent number: 7056032Abstract: A transceiver assembly for use in fiber optic communications systems where multiple optical fibers are used in transmitting and receiving optical signals. The assembly is adapted for being mechanically and optically connected with a ferrule supporting a set of optical communications fibers. The transceiver assembly supports an optoelectronic device having a corresponding set of photoactive components which are operative for either converting photonic signals to electrical signals (in a receiver) or converting electrical signals to photonic signals (in a transmitter). The transceiver assembly includes a frame section having a carrier which is precisely fabricated for supporting the optoelectronic device and includes an alignment structure for cooperating with the optical ferrule to align the photoactive components with the fibers in the ferrule.Type: GrantFiled: September 17, 2001Date of Patent: June 6, 2006Assignee: Stratos International, Inc.Inventors: Hengju Cheng, Lee L.

Publication number: 20050196109Abstract: An optical module that may be used in small-form factor pluggable applications includes a delatching/latching mechanism. The optical module may be an optical transceiver, for example, and the delatching/latching mechanism may allow for improved insertion and removal of the optical module from a cage in a computer board assembly. A latching assembly that assists in latching and delatching may include a latching member having a slotted mating element that is in contact with, and rotates relative to a substantially-fixed pivot element. Rotation may be achieved via a rotatable actuator having a cam engaging a cam follower. Numerous example biasing apparatuses are described to bias the latching assembly to its latched position and to promote contact between the mating element and the pivot element.Type: ApplicationFiled: March 18, 2004Publication date: September 8, 2005Applicant: INTEL CORPORATIONInventors: Brian Kim, William Wang

Patent number: 6739766Abstract: A lens array for use in fiber optic communications modules where multiple optical fibers are used in either transmitting or receiving optical signals. The lens array is adapted for optically interfacing a set of photoactive components such as semiconductor lasers or photo diodes deployed on an integrated circuit chip with a set of optical communications fibers supported in a ferrule. The individual lens elements within the array are shaped to have a greater height than width and are fitted together by being truncated along their boundaries with adjoining lenses. The increased height of the lens elements allows them to gather and transfer more light between the photoactive components and the optical fibers.Type: GrantFiled: December 17, 2001Date of Patent: May 25, 2004Assignee: Stratos International, Inc.Inventors: Lee L.
