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 19):
The PON of  claim 18 , wherein the first ONU is further configured to transmit a first upstream optical signal towards the OLT using time-division multiple access (TDMA), wherein the first upstream optical signal comprises a third band, wherein the first upstream optical signal is centered at a wavelength, wherein the second ONU is further configured to transmit a second upstream optical signal towards the OLT using TDMA, wherein the second upstream optical signal comprises a fourth band and a fifth band, wherein the second upstream optical signal is centered at the wavelength, and wherein the OLT is further configured to receive the first upstream optical signal and the second upstream optical signal at different times via the TDMA.
