ABSTRACT:
A method of determining a length Ldat least representative of the length of a passage along which an optical unit or cable is to be installed by blowing, comprises the steps of flowing a pressurised gas into the passage at a substantially constant pressure P1and substantially constant flow rate Vfuntil gas pressure within the passage reaches a predetermined level P2. The time period tfduring which the pressurised gas was flowed into the passage is determined and then the length Ldis determined by reference to the time period tf.
