40-Gb/s card-edge connected optical transceiver using novel high-speed connector

A novel card-edge connector is proposed that achieves high-speed and compactness through the use of a novel structure with sub-assemblies of a terminal electrode module. An eight-channel double-sided mount, card-edge-connected optical transceiver module was developed by using the connector and our enabling technologies consisting of a highspeed FPC connector, an inductive peaking line, and an integrated lens on a photo diode. Clear eye openings and error-free operation were obtained at 40 Gb/s.
