摘要： A transmitter and receiver integrated optical sub-assembly includes a housing including a side wall structure and a bottom wall, a transmitter-side optical receptacle and a receiver-side optical receptacle attached to the side wall structure, a second circuit board inserted into the housing, laser diodes and photo diodes arranged on the bottom wall, a transmitter-side optical system that is disposed on the bottom wall and combines optical signals from the laser diodes, a receiver-side optical system that is disposed on the bottom wall and splits an optical signal from the receiver-side optical receptacle, a driver integrated circuit, and an amplifying integrated circuit. In the transmitter and receiver integrated optical sub-assembly, electrodes formed at the other end portion of the second circuit board are connected to the driver integrated circuit and the amplifying integrated circuit.

摘要： A cable connection structure is provided with an electronic component including electrodes on an electrode-forming surface, a cable including electric wires connected to the electrodes respectively, and a buried member which is composed of a cured resin and embedded with the electric wires. At least three electric wires are separating wires including separating regions being separated from each other in the normal direction as being distant from the electrode-forming surface. At least three electrodes are arranged side by side on a virtual circle. At least three separating wires are connected to the at least three electrodes. The separating regions of the at least three separating wires are provided to be located eccentric radially outwardly in the virtual circle as being distant from the electrode surface in the normal direction of the electrode-forming surface. An angle between the separating region and the normal direction of the electrode-forming surface is 10 degrees or more and 45 degrees or less.

摘要： A multiplexing optical system in an optical transmitter module has first to third wavelength selective filters and a reflection mirror. The reflection mirror reflects a fourth optical signal to make it enter the first wavelength selective filter and reflects a third optical signal to make it enter the third wavelength selective filter. The third wavelength selective filter reflects a second optical signal to make it enter the second wavelength selective filter and transmits the third optical signal to make it enter the second wavelength selective filter. The first wavelength selective filter transmits a first optical signal to make it enter the second wavelength selective filter and reflects the fourth optical signal to make it enter the second wavelength selective filter. The second wavelength selective filter transmits the first and fourth optical signals and reflects the second and third optical signals to make them enter a lens.

摘要： An optical transceiver includes: a first WDM filter which reflects a first optical signal from a first light source and passes a second optical signal from a second light source; a first total reflection mirror which reflects the first optical signal to make it enter the first WDM filter; a second total reflection mirror which reflects the second optical signal; and a second WDM filter which reflects the second optical signal reflected by the second total reflection mirror to make it enter the first WDM filter. The first and second WDM filters are disposed on a light path, the first and second light sources are disposed back and forth along the light path on both sides thereof, the first and second total reflection mirrors are disposed outside the light path, and an incident angle of the first optical signal to the first WDM filter is smaller than 45 degrees.

摘要： An electric wire connection structure is composed of insulated electric wires each including a core and an insulation coating covering the core. The cores of the insulated electric wires are connected to pads provided on a substrate. The insulated electric wires are arranged along a predetermined alignment direction and arranged parallel to each other. The insulation coating is removed at a part in a longitudinal direction of each of the insulated electric wires to expose the core. Exposed portions of the cores are connected to the pads, respectively. Some of the insulated electric wires are configured in such a manner that the core is exposed in an area where the insulation coatings of adjacent ones of the other insulated electric wires in the alignment direction are not removed.
