Abstract
An optical transceiver includes an electrical connector, an internal circuit, first switch and second switch. The internal circuit is electrically connected to the apparatus through the electrical connector when the optical transceiver is completely inserted into the apparatus, and generate a switching signal after a first signal pad and a second signal pad in a second row of the electrical connector are electrically connected. The first switch isolates a third signal pad in a first row of the electrical connector when the optical transceiver is not fully inserted, and puts the third signal pad electrically connectable in accordance with the switching signal when the optical transceiver is fully inserted. The second switch isolates a fourth signal pad in the first row when the optical transceiver is not fully inserted, and puts the fourth signal pad electrically connectable in accordance with the switching signal when the optical transceiver is fully inserted.
