Abstract
We demonstrate downstream transmission of a four-channel 40-Gb/s-per-channel time- and wavelength-division-multiplexed PON over a 42-km, 64-split fiber plant using optical duobinary modulation. At 1550 nm, we obtain a reach of 0-26 km or 16-42 km using two dispersion-precompensation values.
Highlights
Optical access systems and core transport systems have distinct attributes and requirements, the historical evolution of commercial core transport can inform the current evolution of access
We demonstrate downstream transmission of a four-channel 40Gb/s-per-channel time- and wavelength-division-multiplexed passive optical network (PON) over a 42-km, 64-split fiber plant using optical duobinary modulation
Operation in O-band would not require dispersion precompensation and a single passive optical network (PON) design could operate over the full 0-40 km range addressed by the ITU-T standard, but would require higher launch power to offset the increased fiber loss
