Disk storage (also sometimes called drive storage) is a data storage mechanism based on a rotating disk. The recording employs various electronic, magnetic, optical, or mechanical changes to the disk's surface layer.
A bundle of optical fibers A TOSLINK fiber optic audio cable with red light shone in one end. An optical fiber, or optical fibre, is a flexible glass or plastic fiber that can transmit light [a] from one end to the other.
Current optical data storage media, such as the CD and DVD store data as a series of reflective marks on an internal surface of a disc. In order to increase storage capacity, it is possible for discs to hold two or even more of these data layers, but their number is severely limited since the addressing laser interacts with every layer that it passes through on the way to and from the ...
From June 2009 to April 2018, Telus resold BCE's satellite Bell Satellite TV service in parts of Alberta and British Columbia as Telus Satellite TV.The agreement was designed to allow Telus the ability to offer a quadruple play of services in markets where it had not yet deployed Optik TV, while also allowing Bell to increase its television market share in Western Canada.
The CRC Handbook of Chemistry and Physics defines specific rotation as: For an optically active substance, defined by [α] θ λ = α/γl, where α is the angle through which plane polarized light is rotated by a solution of mass concentration γ and path length l.
Dispersion-shifted fiber (DSF) is a type of optical fiber made to optimize both low dispersion and low attenuation.. Dispersion Shifted Fiber is a type of single-mode optical fiber with a core-clad index profile tailored to shift the zero-dispersion wavelength from the natural 1300 nm in silica-glass fibers to the minimum-loss window at 1550 nm.
Phase shift through a beam splitter with a dielectric coating. Beam splitters are sometimes used to recombine beams of light, as in a Mach–Zehnder interferometer.In this case there are two incoming beams, and potentially two outgoing beams.
