| PURPOSE:To facilitate the handling of a transmission line and to simplify the connection by providing an electrooptic converting means converting each of a branched electric signal into a visual signal light and constituting an optical fiber with a plastic optical fiber. CONSTITUTION:An electric signal 8 drives a 0.67mum use semiconductor laser device 21 irradiating a visual light and the visual signal light 22 being the output is inputted to a plastic optical fiber 23 having, e.g., 1mm diameter of the core. Thus, the adjustment and connection of the optical system are executed while observing them visually and since the diameter of the core of the plastic optical fiber is considerably larger, the tolerance required for alignment adjustment or connection is relaxed by one digit or over. A light emitting diode is used in place of the semiconductor laser as the electrooptic conversion element. Further, the photodetector for a signal light irradiated from a main system transmission line can be a photo diode. | ||||||

| PURPOSE:To minimize the leakage quantity of a signal, and to improve the transmission quality by covering a light emitting element, photodetector, lens and a filter, respectively, with a light shielding member, except a filter opening part, and inserting individual aperture diaphragm between the light emitting element and the lens and the photodetector and the lens, between the lens and the filter, and into at least one place of the filter opening part. CONSTITUTION:The light whose radiation angle is small, among the lights which is emitted from a light emitting diode 1 is sent out to an optical fiber 5. Among the lights which is emitted from the light emitting diode 1, the light which has a large radiation angle and is not made incident on a lens 32, such as light 71 is brought to light shielding by a light shielding member 81, and attenuated as its multipath reflection is repeated in this member. Also, the light which goes into an opening of the lens 32 but is subjected greatly to an aberration of the lens 32, for instance, such as light 72 is shielded and attenuated by an aperture diaphragm 91 or 92. In such a way, a light radiated into an optical circuit device always becomes only a light whose unnecessary wavelength component is attenuated by a filter 43. | ||||||

| PURPOSE:To obtain a receiver with stable PCM code by providing an integration circuit to the pre-stage of a demodulation circuit to improve the identification performance of a signal and a noise. CONSTITUTION:An LC selection circuit 7 consists of a transistor Q2 and a tuning circuit 6 and outputs a signal in tuning with a carrier frequency received. The signal is integrated by an integration circuit 4 comprising a resistor R1 and a capacitor C1, the integrated signal is subjected to waveform shaping by a waveform shaping circuit 5 comprising a Schmitt trigger circuit or the like and the signal subjected to waveform shaping is demodulated by a demodulation circuit 3 and outputted as a PCM code. Since the signal is the PCM code and has a pulse width over a prescribed value, an output of a prescribed level or over is obtained from the integrated waveform of the signal. When the pulse width is small like a noise, the integrated waveform does not reach a prescribed level or over, then even when the signal C is waveform- shaped normally by the waveform shaping circuit 5, the integrated output of the noise N does not reach an on-level of the waveform shaping circuit 5, then the output by noises N is not obtained. | ||||||

| PURPOSE:To prevent electromagnetic induction and to simplify connection between cabins by using an optical fiber for a transmission line in a vehicle and applying optical space transmission line to the transmission line between the vehicles in the transmission of data where transmission stations in a train and the transmission are arranged. CONSTITUTION:The data transmission line in a train is connected in a loop by data stations ST1-ST3 in each vehicle, an optical fiber cable L, space optical transmitters LTX1-LTX4, between vehicles and space light receivers LRX 1-LRX4.

The optoelectric converter O/E in the LTX converts an optical signal into an electric signal, and amplifies the result, then the E/O generates a space optical signal, which is fed to the LRX. The O/E of the LRX receives the space optical signal and converts it into an electric signal, which is amplified and converted into an optical signal by the E/O and the result is transmitted to the optical fiber L. The optical signal from the optical fiber L is converted (O/E) into an electric signal by the ST and transmitted to the TCU. | ||||||

| PURPOSE:To transmit various signals through one optical fiber cable, by optically transmitting the signals by using a multicolored luminous element at the transmitting side and a color sensor at the receiving side. CONSTITUTION:CPU1 and CPU2 are connected and linked with each other by means of one optical fiber cable 2.

| The invention relates to a method of increasing the signal-to-noise ratio of a periodical electrical signal. In general, noise suppression of a periodical signal may be obtained by means of averaging a number of successive signals. In one embodiment of the present invention, the amplitudes of successive periodical signals are integrated for successive time periods which exclude various signal suppression subperiods. The suppression subperiods may be of variable duration, and are positioned beside each other in consecutive fashion. An overall integration value is also formed, by processing the amplitude of the signal without suppressing any portion thereof. From this overall integration value, the integration values associated with the various suppression subperiods are subtracted. The resulting difference signals are arranged in the same sequence as their associated suppression subperiods so as to produce an output signal having the same general waveform as the periodical signal. In an alternative embodiment, instead of integration values, corresponding average values of the signal amplitude may be used. | ||||||

| PURPOSE:To prevent the transmission of an erroneous signal by bringing the level of a specific edge connector of an input/output module of an optical multiplex transmitter into logical H and detecting the potential of a specific bus on a mother board on the other hand so as to detect the presence of the module on the mother board. CONSTITUTION:When a certain module 2 is assembled to a connector T1, i.e., the mother board 5, the level of a terminal t1 of the connector T1, i.e., the bus A obtains logical H. If the module is not assembled conversely, the level of the terminal t1 of the connector T1, i.e., the bus A obtains logical L. Further, a control module is fitted to the edge connector the same as other modules, the voltage of the bus A is checked in this state and only when the voltage exists, each input/output module is made possible for the operation. Thus, if the input/output module is not assembled to the mother board, the transmission is prevented by reading the state of the bus. | ||||||

The light switching circuit 12 outputs only an signal having an input optical signal to be actually transmitted from an output terminal P0 on the basis of self-control. | ||||||

| PURPOSE:To obtain an optically converted signal with a simple method despite an input of an electric signal of a series different from an optical input signal, by supplying the electric signal, i.e., an input signal of a series different from the optical input signal to an equalizing/amplifying part directly or via an AC connection and then converting the electric signal into an optical signal after reproduction. CONSTITUTION:The supplied electric signal of a series different from an optical input signal is supplied to a termial (c). When this electric signal is extracted to a terminal (e) as an identification output, it is equalized at an equalizing/ amplifying part 2. This equalized output signal is identified through an identifying circuit 3 by the clock signal delivered from a timing circuit 4, and the output of the circuit 3 is obtained at the terminal (e). As a result, a new clock input signal is not required for the input electric signal. Thus the input signal, i.e., the equalized output to be supplied to the circuit 3 and 4 has no difference of input between the optical signal and the electric signal in terms of the potential and the amplitude. Thus, it is possible to always obtain a stable output at both terminals (e) and (f), respectively. | ||||||
