    Cable Attenuation Calculator (dB)

    Why are only certain frequencies available?

    The calculator uses the standard TIA-568.2-D reference frequencies where horizontal-cable insertion-loss limits are tabulated, such as 1, 10, and 100 MHz for Cat 5e and up to 250 or 500 MHz for Cat 6 and Cat 6A. Each category only offers frequencies within its rated bandwidth, so you cannot enter an arbitrary value.
