摘要:
To provide a photoelectric composite wiring component combining both characteristics of low power consumption of transmission over electrical wiring and large transmission capacity of optical transmission over optical wiring, and exhibiting a high power efficiency for the transmission capacity. A mechanism for switching between transmission of a transmission signal over an electrical transmission path and that over an optical transmission path depending on the modulation rate or the transmission rate of the transmission signal is provided. When the modulation rate or the transmission rate of the transmission signal is low, power supply to an optical transmitting/receiving section is stopped and the signal is transmitted over the electrical transmission path, thus achieving low power consumption. When the modulation rate or the transmission rate of the transmission signal is high, the signal is transmitted over the optical transmission path, thus achieving a large transmission capacity.

A board assembly, an optical transceiver using same, and a method for mounting a board assembly that can relax a stress occurred at a flexible board. A board assembly 1 comprises a flexible board 2, a first rigid board 3, and a second rigid board 4. The first rigid board 3 and the second rigid board 4 are connected with each other by means of the flexible board 2. Since the flexible board 2 is preformed before the attachment, the stress occurred at the flexible board 2 can be relaxed.
