26-Gb/s DMT Transmission Using Full C -Band Tunable VCSEL for Converged PONs
IEEE Photonics Technology Letters(2017)
Abstract
Wavelength division multiplex (WDM) passive optical network (PON) is considered for converged fixed mobile broadband access networking. We propose to utilize low-cost tunable lasers at the remote sites, together with a centralized wavelength locker. Practical implementations require a transparently added downstream signaling channel and upstream per-channel pilot tones for channel tagging and remo...
