Abstract
The disclosure describes an optical network terminal (ONT) for use in a passive optical network (PON) that includes power conversion circuitry to accommodate a variety of power source options. In particular, the power conversion circuitry converts a wide range of input direct current (DC) voltages to a DC supply voltage that powers ONT circuitry that supports communication of information via the PON.
Claims35
An optical network termination (ONT) for use in a passive optical network (PON), the ONT comprising:
- ONT circuitry to support communication of information via the PON;
- and
- power conversion circuitry to provide operating power to the ONT circuitry, wherein the power conversion circuitry is capable of converting a range of input voltages to a supply voltage that powers the ONT circuitry.
A method for powering an optical network termination (ONT) for use in a passive optical network (PON), the method comprising:
- generating an input voltage;
- and
- converting the input voltage to a supply voltage to power circuitry within the ONT using power conversion circuitry that is capable of converting a range of input voltages to the supply voltage.
An optical network termination (ONT) for use in a passive optical network (PON), the ONT comprising:
- ONT circuitry to support communication of information via the PON;
- and
- power conversion means for providing operating power to the ONT circuitry, wherein the power conversion means is capable of converting a range of input voltages to a supply voltage that powers the ONT circuitry.
The ONT of 24, wherein the power conversion means is coupled to an offline converter to receive the input voltage, wherein the offline converter converts power from an alternating current (AC) power supply to a direct current (DC) input voltage.
