20090175579 | OPTICAL TRANSMISSION MODULE, CONNECTING PART, AND ELECTRONIC DEVICE HAVING OPTICAL TRANSMISSION MODULE - A connection member electrically connects an optical element configured to convert an electric signal to an optical signal or to convert an optical signal to an electric signal, a first substrate including an incident/releasing port of an optical transmission path for an optical signal at least one end portion thereof, and a second substrate to each other. The optical transmission path is optically coupled with the optical element to transmit the optical the connection. The connection member includes a connection unit connected to the second substrate and a holding unit having elasticity and holding the first substrate. The holding unit is provided with an electrode at a connecting position to the first substrate, and the holding unit holds the first substrate by connecting the first substrate to the electrode. | 07-09-2009 |
20100046956 | OPTICAL TRANSMISSION SYSTEM AND ELECTRONIC DEVICE - A light transmission system includes a core for transmitting a clock signal as an optical signal, a core for transmitting a data signal or a control signal as the optical signal in a first direction, which is a direction same as a transmission direction of the clock signal, and a core for transmitting the data signal or the control signal as the optical signal in a second direction, which is an opposite direction to the transmission direction of the clock signal are arranged, thereby bi-directionally transmitting the data signal or the control signal. | 02-25-2010 |
20100119236 | OPTICAL TRANSMISSION MODULE AND ELECTRONIC DEVICE - A light transmission module has a light transmitting unit having a light emitting portion for outputting an optical signal corresponding to a data signal input as an electrical signal, and a first power supply controller for controlling a drive power supply of the light emitting portion, a light transmission path for transmitting the optical signal introduced from the light transmitting unit, a light receiving unit having a light receiving portion for receiving the optical signal output from the light transmission path and outputting an electrical signal corresponding to the optical signal, and a second power supply controller for controlling a drive power supply of the light receiving portion, and at least one electrical transmission path, connecting the light transmitting unit and the light receiving unit, for transmitting a control signal for controlling power supply to the light emitting portion and the light receiving portion to the first power supply controller and the second power supply controller. The first power supply controller and the second power supply controller control the power supply to the light emitting portion and the light receiving portion based on the control signal input via the electrical transmission path. | 05-13-2010 |
20100124422 | OPTICAL TRANSMISSION MODULE - A light transmission module includes an optical converter for converting an electrical signal to an optical signal; a light transmission path for transmitting the optical signal converted by the optical converter; an electrical transmission path for transmitting an input electrical signal; and a control instructing unit for instructing stop of drive to the optical converter based on a detection of an input electrical signal. When an input electrical signal having a predetermined frequency is detected, the input electrical signal having the predetermined frequency is converted to an optical signal and transmitted in the light transmission path. When input of an electrical signal other than the predetermined frequency is detected, the electrical signal other than the predetermined frequency is transmitted by the electrical transmission path without being converted to an optical signal due to the stop of the drive of the optical converter. | 05-20-2010 |
