Abstract
Disclosed is a mixed fiber adapter cable, which is capable of performing direct data transfers from a multi-mode transceiver of a first FDDI node and a single-mode transceiver of a second FDDI node. The mixed fiber adapter cable comprises a multi-mode graded index optical fiber and a single-mode step index optical fiber. The multi-mode graded index fiber conducts an optical signal from an LED source of a multi-mode FDDI connector/transceiver combination to a photodetector receiver of a single-mode connector/transceiver. Conversely, the single-mode step index fiber conducts an optical signal from a laser source of a single-mode FDDI connector/transceiver combination to a photodetector receiver of the multi-mode connector/transceiver at the other end. This adapter cable is possible because the photodetectors of both the single-mode transceiver and the multi-mode transceiver accept optical input from either source with corresponding fiber type. Thus, the mixed fiber adapter cable will permit laser signals to be transmitted from the single-mode transceiver to the multi-mode transceiver and light signals to be transmitted from the multi-mode transceiver to the single-mode transceiver.
