ABSTRACT:
A fiber optic digital communication system and associated transponder architecture interfaces Gigabit Ethernet digital data over an extended range fiber optic link (e.g. upwards of 30 to 100 km), using digital data signal regeneration and optical signal processing components, that pre- and post-compensate for distortion and timing jitter, and thereby ensure accurate regeneration of the data at the far end of the extended distance fiber optic link. Regeneration in both the transmit and receive paths compensates for signal degradation resulting from the very substantial `long haul` fiber distance between transponder sites, and timing jitter customarily present in low cost short haul fiber optic transceiver components. A high speed, low jitter, limiting current driver drives a distributed feedback laser, minimizing jitter generation, and optimizing range extension margin.
