  • High dynamic range OTDR data acquisition circuit
    Patent number: 5485264
    Abstract: An OTDR stores data samples in a predetermined sequence in a memory. Data is read from and written to the memory in the predetermined sequence by application of successive control signals. The stored data is read, added to a correlated sample of a new signal and the result stored to maintain the predetermined sequence of samples. Successive tests thus accumulate samples in sequence to provide an indication of the variation of the signal as the light pulse passes along the fiber under tests.
