High performance gigabit passive optical network

A device comprising:

• a fixed wavelength optical source to generate a first optical signal associated with a first wavelength;
• and
• a wave guide assembly connected to the fixed wavelength optical source, the optical sensor, and an optical network, where the wave guide assembly includes a plurality of fixed wavelength optical filter elements that pass optical signals associated with a respective plurality of wavelengths, where the wave guide assembly is to:
• direct the first optical signal generated the fixed wavelength optical source to the optical network,
• detect a second wavelength associated with a second optical signal present on the optical network,
• activate, based on the second wavelength, one of the plurality of fixed wavelength optical filter elements, where the one of the plurality of fixed wavelength optical filter elements transmits the second wavelength and blocks other wavelengths carried on the optical network, including the first wavelength, and
• direct, via the one of the plurality of fixed wavelength optical filters, the second optical signal from the optical network to an optical sensor.

A method comprising:

• transmitting, by an optical device, a first optical signal, associated with a first wavelength, to an optical network;
