Filed:

Jul 19, 2005

Appl. No.:

11/185008

Inventors:

Thomas Whitehead - Chicago IL, US
Matthew Block - Maple Park IL, US
John Mszal - Bolingbrook IL, US
John Dallesasse - Geneva IL, US
Dean Richardson - Wilmette IL, US
Anthony Moretti - Saint Charles IL, US

Assignee:

Emcore Corporation - Albuquerque NM

International Classification:

H04B 10/00

US Classification:

398138, 398164

Abstract:

A hermetically sealed optical transmitter module for use in an optical transceiver converting and coupling an information-containing electrical signal with an optical fiber. A plurality of semiconductor lasers are provided on a common support in the housing for converting between an information-containing electrical signal and a modulated optical signal corresponding to the electrical signal according to a standardized optical communications protocol, such as the IEEE 802. 3ae 10 Gigabit BASE LX4 physical layer.
