Title: Optical signal switching device
Inventor: KAJITANI SHUNICHI
IPC: H04B10/27
Filed: 1989-04-13
Abstract: PURPOSE:To constitute a reception terminal equipment having plural outputs through the use of one photoelectric converter by providing a selecting circuit to time-serially select plural arbitrary signals among plural optical signals in the time of one bit of the optical signal outputted from an optical branching device and to output the optical signal to be time-division multiplexed. CONSTITUTION:As selecting circuits (3-1)-(3-m), optical matrix switches in a tree constitution where a connected condition can be switched at the high speed, are used. The selecting circuits (3-1)-(3-m) input the optical signals outputted from the optical branching devices (2-1)-(2-n), select plural arbitrary signals out of plural optical signals time-serially by switching them at the high speed in the time of one bit and output the signal to be time-division-multiplexed. Thus, since the time division multiplexed signal can be generated by selecting plural optical signals and, simultaneously, can be made as the optical signal as it is when photoelectric converters (5-1)-(5-m) and time division separating circuits (6-1)-(6-m) are provided, light receiving terminals (7-1)-(7-m) having plural outputs can be composed by using one photoelectric converter.

Filed: 1985-05-07
Abstract: PURPOSE:To reduce an oscillating phenomenon by forming a feedback circuit for superposing a feedback current from respective bases of a pair of pnp transistor (TR) to a reference current through an amplifier and a resistor for controlling gain. CONSTITUTION:When the reference current I1 determined by a constant current circuit CS1 flows into a current mirror circuit consisting of the pnp TRs Q1, Q2, an output current I2 flows into the TR Q2 and a load circuit RL. The current of IbQ1+IbQ2 flows into the resistor R1 and a current fed back from the base of a TR Q3 to the collector of the TR Q1, i.e. to the current course of the reference current I1, is determined by IbQ1+IbQ2/hFEQ3. The emitter resistance reQ3 of the TR Q3 is increased by connecting the resistor R1 and the gain of a closed loop circuit which is the current course of the feedback current is reduced. Consequently, the oscillation phenomenon is reduced.
