1. An apparatus comprising:
- a conduit including;
a tube having a water defining an interior volume of the tube;
one or more optical fibers disposed within the interior volume of the tube, wherein;
the wall of the tube includes a plurality of vents, each vent passing between an outer surface of the wall of the tube and the interior volume, the plurality of vents disposed along a length of the tube and having a distance therebetween;
wherein the vents are configured to establish fluid communication between the interior volume of the outer jacket and the interior volume of the tube;
wherein the vents have a population and size configured to provide a flow rate into the interior volume of the tube equal to or greater than 1000 cubic millimeters/sec; and
wherein the distance between adjacent vents along the length of the tube is in a range of 25 meters to 250 meters.
