We probe the limits, both experimentally and analytically, of passive optical network (PON) monitoring using periodic coding technology. The experimental demonstration focuses on a 16 customer PON with a 20 km feeder fiber followed by either a single cluster or a tiered hierarchy. A directly modulated laser modulated at 1 GHz was used to generate the monitoring probe signals. The measured data from...
In this paper, we study bandwidth management of a wireless/optical based access/metro network in support of voice and data services. For voice services, we use a finite state Markov Chain to estimate the blocking probability of voice circuits over an Adaptive modulation and coding wireless channel, as a function of the channel parameters. For data services, we evaluate a rate matching and a buffer...
Optical communication systems based on dense wavelength division multiplexing (DWDM) would benefit from the ability to adjust the operating wavelength of a laser transmitter. Previous attempts, including thermal adjustment, etalon based wavelength locking, and various types of optical frequency and phase locked loops such as the Pound-Drever-Hall technique suffer from weaknesses including sensitivity...
