Passive remote detection of gas flow and cable arrival
First Claim
1. A system, for use in installation of blown fiber through a fiber tube having a first end and a second end for detecting a signal indicative of a presence of at least one of a gas flow or an optical fiber at the second end of the fiber tube, the system comprising:
- a sensor configured to generate a signal at the second end of the fiber tube upon sensing the presence of the at least one of the gas flow or the optical fiber at the second end of the fiber tube;
a gas vibration detector installed at the first end of the fiber tube configured to acoustically couple with the first end of the fiber tube for receiving the signal generated at the second end of the fiber tube; and
a processor arranged to receive an input from the gas vibration detector,such that the generated signal is detected at the first end of the fiber tube.

Abstract
A system for use in installation of blown fiber for detecting a signal indicative of presence of at least one of a gas flow or an optical fiber at a remote location, comprising a gas vibration detector configured to acoustically couple with an installation duct through which the signal can travel after its generation at the remote location, and a processor arranged to receive an input from the vibration detector and to process the input to identify the signal present within the input; and a sensor for generating the signal upon sensing the presence of at least one of the gas flow or the optical fiber at the remote location. The signal can be provided by a whistle mounted on the remote end of the installation duct. The vibration sensor is typically a microphone.
