Title: Optical output disconnection detection circuit
Inventor: SUZUKI MUNETOSHI
IPC: H04B10/556
Filed: 1997-07-02
Abstract: PROBLEM TO BE SOLVED: To instantaneously detect an optical output disconnection in case of deterioration of a light emitting element light output in an optical transmission line of burst signals. SOLUTION: An optical output signal 9 from a light emitting element 2 driven by a light emitting element operating circuit 1, to which a transmission signal 8 of a burst state is inputted, is received by a light output monitoring detector 3 for a light emitting element. Its output signal 10 is outputted as an output signal 11 whose polarities are reversed for transmission period and non-transmission period by a monitoring signal instantaneous peak detection circuit 4. An amplifier discrimination circuit 5 compares the output signal 11 with a set value of a reference voltage source 6 and outputs an output signal 12 of a fixed amplitude when a level of the output signal 11 is higher than the set value of the reference voltage source 6.  This output signal 12 and a burst gate signal 13 for outputting the transmission period as a low level and non-transmission period a high level are inputted to a NAND circuit 7 for logical discrimination and their output becomes an optical output disconnection detection signal 14.
