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 16):
The ONU of  claim 15 , wherein the first baseband IM signal is a first non-return-to-zero (NRZ) signal or a first four-level pulse-amplitude modulation (PAM-4) signal, and wherein the second baseband IM signal is a second NRZ signal or a second PAM-4 signal.
