US Patent:

7354203, Apr 8, 2008

Filed:

Jul 11, 2005

Appl. No.:

11/178624

Inventors:

Stefan Pfnuer - Los Gatos CA, US
Tengda Du - Fremont CA, US
Kevin Zhang - San Jose CA, US
Julie S. Eng - Los Altos CA, US
Axel Mehnert - Sunnyvale CA, US

Assignee:

Finisar Corporation - Sunnyvale CA

International Classification:

G02B 6/36

US Classification:

385 92

Abstract:

A package for maintaining alignment of components includes a frame and a beam with the beam attached to the frame and one end of the beam. One or more components are mounted to the beam. The frame and a portion of the beam are separated from each other by a channel which allows portions of the beam to flex substantially independently of the frame when a force is applied to the frame. Thus, the effects resulting from forces applied to the frame are not experienced by the beam, or are at least attenuated, so that the alignment of the components mounted on the beam is substantially preserved.

Abstract:

This disclosure concerns optoelectronic transceivers. In one example, a transceiver is implemented as an uncompensated architecture that is substantially compliant with the SFP MSA and is capable of effective operation at a data rate of about 8. 5 Gb/s. The transceiver includes a TOSA, ROSA, a printed circuit board, an LDPA disposed on the printed circuit board and configured for communication with the TOSA and the ROSA. Finally, the transceiver includes SFP compliant optical and electrical connections.
