Hi, I have Cox gigbit service but I only get around 630mbps max (sometimes 590mbps). A cutoff frequency is a point at which energy flowing through the EM system begins to be reduced, by attenuation or reflected, rather than passing through the line. 2,474 67. To reduce the losses from the skin affect, a larger diameter coaxial cable can be used but increasing the coaxial cables dimensions will reduce the maximum frequency the coaxial cable can transmit. The current MoCA cable products only work with cable TV, FiOS or off-air TV services. Cable television is a system of delivering television programming to consumers via radio frequency (RF) signals transmitted through coaxial cables, or in more recent systems, light pulses through fibre-optic cables.This contrasts with broadcast television (also known as terrestrial television), in which the television signal is transmitted over the air by radio waves … Two important concepts of note when discussing frequency in coaxial cable are skin-depth and cutoff frequency. NOTE: If the either of the signal levels are outside of the acceptable range, power cycle or factory reset the modem. Hence, a coaxial cable cutoff frequency could be where the coaxial cable remains within specification, or within a reasonable margin to avoid transverse-magnetic (TM) or transverse-electric (TE) propagation modes. Higher modes are excited at frequencies above the cutoff frequency when the first higher-order mode, called TE11, is also allowed to propagate. All risk relating to its use is assumed by the user. In most of its service locations throughout the United States, Cox offers residential packages with downstream speeds of up to 940 Mbps.
