Light source for a passive optical network |
摘要 |
A method comprises: receiving an RF signal; providing an RF signal level; setting a DC optical power level at one of at least two levels depending on whether the RF signal level is above or below an RF threshold; and modulating with the RF signal optical output power about the DC optical power level. An apparatus comprises: a light source; an RF detector arranged to receive the RF signal and to provide the RF signal level; an optical power control circuit coupled to the RF detector and to the light source that includes a comparator and is arranged to set the DC optical power level according to the RF signal level; and an optical modulator coupled to the light source and arranged to receive the RF signal and to modulate therewith optical output power about the DC set point.
