Abstract:
An apparatus comprises a DAC configured to convert a digital electrical signal to an analog electrical signal and a laser coupled to the DAC. The laser is configured to generate an optical signal using the analog electrical signal for modulation, the optical signal is a band-multiplexed optical signal comprising frequency bands, the frequency bands comprise a lowest-frequency band, and the lowest-frequency band comprises a baseband IM signal. The laser is configured to transmit the optical signal. A PON comprises an OLT configured to transmit a downstream optical signal, the downstream optical signal is a band-multiplexed optical signal comprising a first band and a second band. The PON includes a first ONU configured to receive the downstream optical signal and equalize only the first band; and a second ONU configured to receive the downstream optical signal and equalize the first band and the second band.

Claim (Index 18):
A passive optical network (PON) comprising:\n an optical line terminal (OLT) configured to transmit a downstream optical signal, the downstream optical signal is a band-multiplexed optical signal comprising a first band and a second band; a first optical network unit (ONU) comprising:\n a first photodiode (PD) configured to receive the downstream optical signal, and \n a first equalizer configured to equalize only the first band; and \n a second ONU comprising:\n a second PD configured to receive the downstream optical signal, \n a second band separator configured to separate the first band from the second band, and \n a second equalizer coupled to the second band separator and configured to equalize the first band and the second band.
