The present invention relates to a hybrid connector. The connector comprises an insulating housing having parallel rows of first and second terminals disposed in the housing. Each first and second terminal includes a terminal portion configured to make contact with an electrically conductive trace of a circuit board; and a mating portion configured to contact a terminal of a mating connector, themating portions of the first terminals parallel to and facing the mating portions of the second terminals. The housing defines a cavity formed therein between the mating portions of the first and second terminals, wherein the cavity defining a cavity opening at an external surface of the housing for receiving light therefrom. An optical relay portion is disposed in the cavity, wherein the opticalrelay portion comprises at least one of an optical transceiver, an optical lens and an optical waveguide.
Description
technical field [0001] The present invention relates to hybrid cable-to-board connectors, and more particularly to fine-pitch, high-speed hybrid cable-to-board connection systems for midplane applications. Background technique [0002] In traditional electronic equipment such as portable communication devices and notebook computers, board-to-board connections are typically made with low-profile board-to-board electrical connectors, which enable circuitry on different circuit boards to be placed in close proximity to each other. However, as data rates continue to increase, electrical connectors may not be able to handle the amount of data that needs to be transferred. [0003] Transmitting large amounts of high-speed (>10Gbps) digital signals from onboard modules to the midplane or backplane can be challenging. The higher the frequency of the signal, the greater the loss caused by the signal passing through the copper traces on the printed circuit board (PCB). Additional...
