In an optical fiber, the normalized frequency, V (also called the V number), is given by = =, where a is the core radius, λ is the wavelength in vacuum, n 1 is the maximum refractive index of the core, n 2 is the refractive index of the homogeneous cladding, and applying the usual definition of the numerical aperture NA.
The variously three to six larger commercial U.S. television networks each has its schedule. which is altered each year (and usually more frequently), and the introductions and relevant articles provide a comprehensive review for each year, from the 1946 season to the present.

An eight-way optical signal splitter to feed eight virtual LNBs or further splitters from a single optical feed. While optical fibre has been used for telephone and Internet backbone data, and even for television and multimedia carriage for terrestrial cable, for many years, use for satellite IF distribution has been held back by considerations of cost and installation convenience.
The schedule is followed by a list per network of returning series; no new series, but only one series is canceled after the 2019–20 season are included at present, as the daytime schedules of the four major networks that offer morning and/or afternoon programming is expected to remain consistent with the prior television season.

An intermediate line repeater is placed approximately every 80–100 km to compensate for the loss of optical power as the signal travels along the fiber. The 'multi-wavelength optical signal' is amplified by an EDFA, which usually consists of several amplifier stages. An intermediate optical terminal, or optical add-drop multiplexer (OADM ...
