TL;DR: This work proposes a service-level-agreement-based scheduling scheme for passive optical networks in which the optical line terminal can adjust the sleep time and the optical network unit can quit sleep mode for sending high-priority packets.

TL;DR: This work proposed a cost-effective next generation mobile fronthaul architecture with multi-IF carrier transmission scheme and investigated the system performances under various IF carrier operating conditions.

TL;DR: In this article, a spectral filter whose transmission peak is tuned to "mark" wavelength of the modulated laser output is used to suppress the intersymbol interference induced by nonuniform frequency modulation response of semiconductor lasers.

TL;DR: The benefits achieved by SDONs for network operators, and also some of the important and relevant research problems that need to be addressed are outlined.

TL;DR: In this paper, a method for compensating polarization mode dispersion is proposed, which includes transforming states and directions of polarization components of an optical signal received from the optical transmission line, rotating the polarization component of the optical signal output from the polarization controller, separating two orthogonal polarization components from the output, and controlling the polarization rotator by comparing the optical power of the first polarization component transmitted to the output path with an optical power transmitted to a monitoring path.
