Claims19
1-15. (canceled)
An optical network unit for an optical network comprising:
- (a) a light sensitive diode suitable to sense light from said optical network and provide a first output in response thereto;
- (b) a transimpedance amplifier that receives said first output and provides a second output in response thereto;
- (c) a switch selectively providing said second output to a first amplifier or a second amplifier;
- (d) said first amplifier receiving said second output and amplifying said second output based upon a limiting amplifier to provide a limited amplified output;
- (e) said second amplifier receiving said second output and amplifying said second output based upon a non-limiting amplifier to provide a non-limited amplified output;
- (f) a processor selectively receiving either of said limited amplified output and said non-limited amplified output for subsequent processing.

An optical network unit for an optical network comprising:
- (a) a conversion module that receives an optical signal from said optical network and in response thereto provides a voltage output;
- (b) a switch selectively providing said voltage output to a first amplifier or a second amplifier;
- (c) said first amplifier receiving said voltage output and amplifying said voltage output based upon a limiting amplifier to provide a limited amplified output;
- (d) said second amplifier receiving said voltage output and amplifying said voltage output based upon a non-limiting amplifier to provide a non-limited amplified output;
- (e) a processor selectively receiving either of said limited amplified output and said non-limited amplified output for subsequent processing.

An optical network unit for an optical network comprising:
- (a) said optical network unit including a laser providing an optical output at a selected frequency;
- (b) a first laser driver that includes a first bias current source interconnected with said laser to provide a first bias current thereto and a first modulation current source interconnected with said laser to provide a first modulation current thereto;
- (c) a second laser driver that includes a second bias current source interconnected with said laser to provide a second bias current thereto and a second modulation current source interconnected with said laser to provide a second modulation current thereto;
- (d) said laser driver controller configured in a first configuration to selectively cause to be provided at least one of said first bias current and said first modulation current to said laser by selection of at least one of said first bias current source and said first modulation current source thereby providing two different current levels to said laser, without selecting said second bias current source nor said second modulation current source of said second laser driver;
- (e) said laser driver controller configured in a second configuration to selectively cause to be provided at least one of said first bias current, said first modulation current, said second bias current, and said second modulation current to said laser by selection of at least one of said first bias current source, said first modulation current source, said second bias current source, and said second modulation current source thereby providing four different current levels to said laser.
