At the regional cable television headend | headend, the TV channels are sent multiplexed on a light beam which travels through optical fiber trunklines, which fan out from distribution hubs to optical nodes in local communities.

At the subscriber's residence, either the subscriber's television or a set-top box provided by the cable company translates the desired channel back to its original frequency ( baseband ), and it is displayed on the screen.

At the optical node, the light beam from the fiber is translated back to an electrical signal and carried by coaxial cable distribution lines on utility poles, from which cables branch out to subscriber residences.

At the same time, the advent of fibre-optic technology enabled companies to extend their systems to nearby towns and villages that by themselves were not viable cable television markets.

At this time only cable provider Caiway ( available in a limited number of towns in the center of the country ) is broadcasting the channel.

At specific points indicated by the pattern, the cable needle is moved, the stitches on it are worked by the other needles, then the cable needle is turned around to a different position to create the cable twist.

At that point, the U. S. ambassador sent a cable to the White House saying it would be " ill-advised " to call off the bombing, because such an action would help the Sandinistas gain power.

At the land-end in Gallanach Bay near Oban, Scotland, the cable joined to a coaxial line carrying 900 inland and transatlantic circuits to the International Exchange in London.

At the cable source or headend, electronic upconverters convert each incoming television channel to a new, higher frequency.

At the consumer's home, the cable set top box has a downconverter that mixes the incoming signal at frequency f < sub > CH </ sub >+ f < sub > LO </ sub > with the same local oscillator frequency f < sub > LO </ sub > creating the difference heterodyne, converting the television channel back to its original frequency: ( f < sub > CH </ sub >+ f < sub > LO </ sub >) − f < sub > LO </ sub > = f < sub > CH </ sub >.

At its height the cable system was one of the largest in the world, with of double track, 1200 grips and trailers and 17 routes covering ( 103. 2 route km or 64. 12 route miles ).

At the dawn of the cable television era, many regional sports networks ( RSNs ) vied to compete with the largest national sports network, ESPN.

At frequencies below 10 MHz the impedance mismatch between a 50 ohm connector or cable and a 75 ohm one has negligible effects.

At the cable company's set top box, the signal is converted to a lower IF of 480 MHz for filtering, by a variable frequency oscillator.

At the destination end of the cable or fiber, for each channel, an electronic filter extracts the channel's signal from all the other channels.

At first the system was deployed using RG-62 / U coax cable ( commonly used in IBM mainframe environments to connect 3270 terminals and controllers ), but later added support for twisted-pair and fibre media.

At low airspeeds, the control surfaces became ineffective and could readily lead to loss of control, particularly during landing.

At Port-Lyautey, the landing troops were uncertain of their position, and the second wave was delayed.
