Video pair cable is a transmission cable containing low-loss pairs with an impedance of 125 ohms, used for TV pickups, closed-circuit television, telephone carrier circuits, and similar applications.
Video pair cable is a transmission cable built with low-loss twisted pairs having a characteristic impedance of 125 ohms, designed to carry video and similar wideband signals. The controlled impedance and low loss of the pairs preserve the quality of the signals over distance, which is important for video and carrier applications. Video pair cable is used for television pickups, closed-circuit television, telephone carrier circuits, and similar wideband transmission.
Because video and carrier signals occupy wide bandwidths, the cable's low loss and consistent 125 ohm impedance keep the signal intact and matched along the run. The balanced pair construction supports the transmission of these signals with good noise rejection.
In commercial and industrial systems, video pair cable carries television and carrier signals in broadcast, surveillance, and communication applications. Recognizing the construction helps in understanding cable matched to wideband video and carrier circuits.

At Windy City Wire, an understanding of transmission cable, including video pair cable, supports the selection of cable matched to the signal. Recognizing how low-loss 125 ohm pairs suit video and carrier circuits helps illustrate the range of cable available for commercial and industrial transmission applications.
