Abstract: A method, for use in connection with installing a cable into a conduit (4) having a first end and a second end (12), of detecting whether air is flowing from the first end to the second end, the method including the steps of: —providing a movement sensor (10) within or proximate to the conduit; —providing an air flow (14) into the conduit from the first end; and —detecting that the air is flowing to the second end when the air flow disrupt the movement sensor.

Abstract: A method for use in connection with installing a fiber unit into a conduit having a first end and a second end, the method being suitable to detect when the fiber unit introduced into the first end arrives at the second end. The fiber unit is introduced into the conduit from the first end and installed towards the second end; introducing a light with a light source into the fiber unit at the first end; detecting reflected light in the fiber unit with a light detector at the first end, and detecting changes in the reflected light, whereby an operator may determine that the fiber unit has arrived at the second end.

Abstract: A method for use in connection with installing a cable into a conduit having a first end and a second end, to confirm whether air introduced into the conduit at the first end is flowing out of the conduit from the second end, the method including the steps of: substantially blocking the second end, so that when the air is introduced into the conduit its flow from the second end will be impeded; introducing a flow of air into the first end; and detecting a change in a property of the air within the conduit whereby it can be confirmed if the air is flowing to the second end.

Abstract: A method for use in connection with installing a fibre unit (10) into a conduit (8) having a first end (6) and a second end, the method being suitable to detect when the fibre unit introduced into the first end arrives at the second end, and comprising the steps of: introducing the fibre unit into the conduit from the first end and installing it towards the second end; introducing light with a light source (30) into the fibre unit at the first end; detecting reflected light in the fibre unit with a light detector (32) at the first end; and detecting changes in the reflected light, whereby an operator may determine that the fibre unit has arrived at the second end.
