Summary

Recommendation ITU-T L.108 (ex. L.79) describes the characteristics, construction and test methods for microduct fibre units and microduct cables that are used with the blowing installation technique. The cable characteristics required for a cable to perform appropriately are described. Also, a method is described for determining whether or not the cable has the required characteristics. The required conditions may differ according to the installation environment; detailed test conditions must be agreed upon between a user and a manufacturer for the environment in which a cable is to be used.
