What is the deal with some companies quoting 750 feet, vs. those who quote 1,000 feet w/ passive devices?
Virtually all reputable UTP manufacturers have similar recommendations for the passive-to-passive applications. With a passive ONLY system, UTP can support 1,000 feet as long as the destination is an analog device such as a video monitor or a common matrix switcher. If the destination is a digital device like a DVR or Multiplexer, then the video inputs on those devices are more sensitive to the signal losses and may experience Video loss detection, or intermittent alarming inherited from a runs over 750 feet.
