fiber optics

Productivity improving technologies (historical) - Fiber optics 1 The diffusion of telephony to households was mature by the arrival of fiber optic communications in the late 1970s. Fiber optics greatly increased the transmission capacity of information over previous copper wires and further lowered the cost of long distance communication.

Soliton - Solitons in fiber optics 1 Much experimentation has been done using solitons in fiber optics applications. Solitons in a fiber optic system are described by the Manakov equations. Solitons' inherent stability make long- distance transmission possible without the use of repeaters, and could potentially double transmission capacity as well.

Charles K. Kao - Fiber optics and communications 1 In 1960s at STL, Kao and his co-workers did their pioneering work in the realisation of fiber optics as a telecommunications medium, by demonstrating that the high- loss of existing fibre optics arose from impurities in the glass, rather than from an underlying problem with the technology itself.

Charles K. Kao - Fiber optics and communications 1 In 1969, Kao with M.W. Jones measured the intrinsic loss of bulk-fused silica at 4 dB/km, which is the first evidence of ultra- transparent glass. Bell Labs started considering fiber optics seriously.

Charles K. Kao - Fiber optics and communications 1 Kao is also a visionary of modern submarine communications cables and largely promoted this idea. He predicted in 1983 that world's seas would be littered with fiber optics, five years ahead of the time that such a trans-oceanic fiber-optic cable first became serviceable.

Alternating current - Fiber optics 1 At frequencies greater than 200GHz, waveguide dimensions become impractically small, and the ohmic heating|ohmic losses in the waveguide walls become large. Instead, fiber optics, which are a form of dielectric waveguides, can be used. For such frequencies, the concepts of voltages and currents are no longer used.

Nonlinear Schrödinger equation - The nonlinear Schrödinger equation in fiber optics 1 In optics, the nonlinear Schrödinger equation occurs in the Manakov system, a model of wave propagation in fiber optics

Numerical aperture - Fiber optics 1 The number of bound transverse mode|modes, the mode volume, is related to the Normalized frequency (fiber optics)|normalized frequency and thus to the NA.

Incident light - Fiber optics 1 * A 'leaky ray' or 'tunneling ray' is a ray in an optical fiber that geometric optics predicts would total internal reflection|totally reflect at the boundary between the Fiber_optics#Principle_of_operation|core and the Cladding (fiber optics)|cladding, but which suffers loss due to the curved core boundary.

Fiber optics 1 Power over Fiber (PoF) optic cables can also work to deliver an electric current for low power electric devices.[ e-introduces-hybrid-fiberpower-cable-system TE introduces hybrid fiber/power cable system], Telecompaper, 10 February 2014 The field of applied science and engineering concerned with the design and application of optical fibers is known as 'fiber optics'.

Fiber optics - Overview 1 Optical fibers typically include a transparency and translucency|transparent core (optical fiber)|core surrounded by a transparent Cladding (fiber optics)|cladding material with a lower index of refraction

Index-matching gel - In fiber optics 1 In fiber optics and telecommunications, an index-matching material may be used in conjunction with pairs of mated connectors or with mechanical splices to reduce signal reflected in the guided mode (known as return loss) (see: Optical fiber connector)
