Recently, various architectures for future networks have been researched and discussed. In one of these approaches, we assume the deployment of an access network in which wavelength division multiplexing (WDM) and time division multiplexing (TDM) techniques will be applied to user and service multiplexing, respectively. In line with the envisioned scenario, we are studying a new access network based...
We report a 1-chip MUX/DEMUX LSI that can handle mixed rate signals at over 10 Gb/s; it is the key technology for future optical access networks that offer highly efficient use of wavelengths in multi-wavelengths systems.
We propose a service rate matching optical receiver module for PS-based WDM PON systems that offer maximum bit rates of over 40 Gb/s. Proposed module provides line rate flexibility with low power consumption.
We propose a multilevel transmission technique using stacked optical binary signals without any loss budget reduction when receiving multilevel signals. The principle is described and the validity of the technique is verified by numerical calculation.
