  • Error detection for fiber distributed interfaced optic link
    Patent number: 5068854
    Abstract: Error detection of digital data transmitted on an optic link is accomplished by creating, before transmission, a check code comprising check bits that correspond to spaced one of the data bits forming the plurality of bits. The check code is then transmitted with the plurality of bits to a receiver, where the plurality of bits are used to create an error code in the same manner as the check code, the error and check codes compare, and an indication of error generated when a miscompare is detected.
