RADIO FREQUENCY BURST MODE OPTICAL TO ELECTRICAL CONVERTER FOR PASSIVE OPTICAL NETWORKS

摘要

An optical to electrical converter that detects RF burst from a terminal on a passive optical network and selectively activates a laser detection circuit and a laser based on the power level of the RF burst such that noise being transmitted from said terminal to a head-end will not activate said laser detection circuit. The RF burst is detected prior to activating the laser via a burst detection circuit which comprises a burst detector and a reference voltage generator.
