Zusammenfassung: | An object of the present invention is a modular optoelectronic connector that can be used especially when high transmission bit rates are encountered. High bit rates of this kind are encountered for example in the field of telecommunications, especially for the interconnection of SDH type telephone exchanges. Each channel of an exchange of this kind must indeed give a bit rate of 622 Mbits. The expected developments are such that these bit rates must be raised to 2.5 Gbits and then 10 Gbits. High bit rates of this kind are furthermore being encountered in more limited spaces, as for example in computer local area networks or in aircraft. The bit rate requirements may then be also high owing to transmissions of image signals. Furthermore, inside one and the same piece of equipment, for example for the connection between several electronic racks in one and the same electronic cabinet, it may be planned to have very high bit rates.
To resolve the problems of the manufacturing costs of an optoclectronic connector, and optoelectronic coupling integrated circuit chip () is mounted directly () into a package () of the connector. This package has an internal shielding metallization and metallizations () connected by microconnection techniques to pads () of the integrated circuit. The integrated circuit has laser diodes () on its surface also connected () to the pads () of this integrated circuit. These laser diodes are spaced out with respect to one another by a distance corresponding to a distance () between the optical fiber terminations () in a standardized optical connector (). The number of elements of the connector is reduced whereas, at the same time, its efficiency in terms of electrical consumption and in terms of transmission quality of a signal is improved. |
