A method for providing tension to a data or power transmission line in a pipe includes inserting a transmission line into a transmission line channel of a pipe. The transmission line has a first end and a second end and is inserted into a first end of the pipe second-end-first and has a first tension-load-supporting mechanism attached to the first end of the transmission line. The method includes applying a first level of tension to the transmission line in the pipe and applying a second tension-load-supporting mechanism to the second end of the transmission line while the first level of tension is applied to the transmission line. The method further includes removing the first level of tension from the transmission line to maintain a second level of tension along the transmission line between the first and second tension-load-supporting mechanisms.
