Patent number: 8175462Abstract: A fiber optic transceiver (FOT) module is provided that has a circuit board attached to the FOT leadframe. The circuit board, which is typically a printed circuit board (PCB), provides several advantages over typical FOT module designs in that it provides additional surface area for mounting additional components, enables components to be moved from the motherboard into the module, allows the I/O pin count of the FOT module to be increased without increasing the width or footprint associated with the module, allows bond wires to be shortened, provides improved performance over changes in temperature, allows manufacturing yield to be improved, and enables improvements in signal integrity to be realized.Type: GrantFiled: January 7, 2009Date of Patent: May 8, 2012Assignee: Avago Technologies Fiber IP (Singapore) Pte. Ltd.Inventors: Tom Sheau Tong Wong, Tze Wei Lim, Adrianus Van Haasteren

Patent number: 8100588Abstract: A small form factor pluggable (SFP) optical transceiver module and method for performing optical communications are provided. The SFP optical transceiver module has a housing to which a duplex receptacle is secured. The duplex receptacle has a C-shaped opening, the upper and lower portions of which are defined by upper and lower flexible retaining elements for receiving and retaining a duplex optical connector therein. An electrical assembly of the module is secured within the transceiver module housing. The electrical assembly comprises a PCB, the back end of which is configured as a plug end for removably plugging the PCB into a receptacle of an external communications management system.Type: GrantFiled: October 8, 2010Date of Patent: January 24, 2012Assignee: Avago Technologies Fiber IP (Singapore) Pte. Ltd.Inventors: Tom Sheau Tung Wong, Adrianus Van Haasteren, Tze Wei Lim

Publication number: 20090269075Abstract: An electro-optical assembly (EA) is provided in which the transmitter and receiver components are integrated together on a single circuit board, which is encapsulated in a single molded EA package. Integrating the transmitter and receiver components on a single circuit board allows the size and complexity of the EA to be greatly reduced as compared to the traditional TO-can and FOT architectures. A standard semiconductor inline automation system and process may be used to manufacture the EA packages so that they may be mass produced with improved throughput, yield and quality as compared to the method currently used to manufacture and assemble the known EA used in the traditional TO-can and FOT architectures.Type: ApplicationFiled: April 24, 2008Publication date: October 29, 2009Applicant: AVAGO TECHNOLOGIES FIBER IP PTE.

Publication number: 20060098292Abstract: In one embodiment, a lens has an object surface and an image surface, with the shape of the image surface being defined by an equation having a conic component and a cone component. The lens may be incorporated into an optical receiver having a photodetector that is positioned to receive light emitted from the image surface of the lens. In some uses, the image surface of the lens mitigates return loss through the lens.Type: ApplicationFiled: November 8, 2004Publication date: May 11, 2006Inventors: Tom Sheau Wong, Adrianus van Haasteren
