The NEPTUNE Scientific Submarine Cable System
The NEPTUNE scientific submarine cable system will “wire” the Juan de Fuca tectonic plate and turn it into an interactive ocean sciences laboratory. NEPTUNE will provide 30 seafloor nodes distributed over a 500 by 1000 km area to which many scientific instruments may be attached. The nodes will supply power at the several kW level and data communications at a Gb/s rate. NEPTUNE will utilize an ...
متن کاملNon-cooperative Diagnosis of Submarine Cable Faults
Submarine cable faults are not uncommon events in the Internet today. However, their impacts on end-to-end path quality have received almost no attention. In this paper, we report path-quality measurement results for a recent SEA-ME-WE 4 cable fault in 2010. Our measurement methodology captures the path-quality degradation due to the cable fault, in terms of delay, asymmetric packet losses, and...
متن کاملWavelength Demultiplexer for Optically Amplified WDM Submarine Cable System
The wavelength demultiplexer, using cascaded optical fiber gratings and circulators, was proposed and developed for application to optically amplified wavelength-division multiplexing (WDM) submarine cable systems with 100GHz channel spacing. Our proposed demultiplexer cannot only achieve high wavelength selectivity, small excess loss and effective allocation of dispersion compensation fibers f...
متن کاملPhysical Oceanography from Deep Ocean Submarine Cable Observatories
Seafloor cabled observatories have an obvious role as part of the sustained infrastructure needed to observe climate variability. To highlight this point a couple of important discoveries of the physical climate of the ocean that have been based on data acquired at open ocean “observatories” are reviewed. Perhaps the more important role for observatories in physical oceanography may be the prov...
متن کاملGalvanic gold plating for fixed dental prosthesis
Metal ceramic partial fixed dental prostheses have been commonly used for the replacement of missing teeth for many years. Because of an increase in the price of gold, base metal alloys have been the choice of alloy for the fabrication of metal ceramic restorations in many dental clinics. Some major disadvantages of base metals are their corrosion and the dark coloration they may cause at the c...
