Link-disjoint routing strategy can offer a set of reliable alternate paths when the active best path fails. However, simply employing a set of fully disjointed paths may not necessarily result in the efficient network resource utilization in some circumstances, which degrades the performance of the network system under a highly loaded traffic condition. In this study, we propose two heuristic link-disjoint...
In this paper, an all optical wavelength multicasting service in AWG-based WDM PON is introduced, and a novel architecture supporting multiple multicasting groups is proposed. The novel characteristic is that different from the PON systems which broadcast the signals to all the receivers, multicasting signals are only delivered to desired users. This restricted member multicasting brings the trusted...
In this paper, an all optical wavelength multicasting service in AWG-based WDM PON is introduced. Two novel architectures of remote node supporting all optical wavelength multicasting functionality are proposed. The interesting characteristic of this function is that, different from the current PON systems which broadcast the signals to all the receivers, here, multicasting signals will be delivered...
AGC-EDFA for the burst-mode signals is one of the most important devices in the next generation WDM. We have realized the AGC-EDFA without gain excursion in 20-ns and 21-dB ramped input with the high-speed VOA.
We investigated a multi-frequency light source with 50-GHz spacing based on the optical frequency comb generation. The error-free 10-Gbps DWDM transmission was successfully achieved over 100-km.
A multi-frequency light source with 50-GHz channel spacing was constructed based on optical frequency comb generation. The error-free 10-Gbps WDM transmission over 100-km was successfully achieved using the multi-frequency light source.
Fiber optic power and signal transmission systems are discussed from the viewpoint of their application to DC powering to information tools such as personal computers. We discuss the system requirements and the technical issues of the system components including high power laser diodes and photovoltaic cells. We also discuss wavelength division multiplexing transmission of power and signal light.
