Title: Light transmitter for burst signal
Inventor: IMAMURA KEIICHI
IPC: H04B10/556
Filed: 1988-05-31
Abstract: PURPOSE:To make the title transmitter suitable for a signal transmission system in which an optical fiber is used by completely getting off signals in a state that the signal to be transmitted is not inputted in a light transmitter which is used for the communication of inter-computer and discriminating whether the signal is in the middle of transmission or silent in a reception side. CONSTITUTION:When the input signal with respect to the light transmitter does not exist or it has terminated, a counter C outputs the silent state signal of '1' and as a result, the input voltage of a non-inverted input in a comparator IC2 becomes higher than the input voltage of an inversion input, whereby it outputs the signal in a low level being the inversion output of the comparator IC2 to the base of a transistor Q4. Thus, the transistor Q4 is set in an interrupted state, and a light-emitting element LD is completely made into a getting off state. When the signal changes after the same signal continues in the counter C, the counter C is reset, outputs the signal state signal of '0', sets the inversion output of the comparator IC2 to '1', conducts the transistor Q4 and outputs an optical signal from the light-emitting element LD.
