Where does the length of the optical cable line refer to
Indicator 1: Transmission network length (Route kilometers) Definition: Transmission network length refers to the physical length of fibre optic cable in a network irrespective of the number of optical fibres contained within the constituent cables of that network (see Indicator 5:. A fiber-optic cable, also known as an optical-fiber cable, is an assembly similar to an electrical cable but containing one or more optical fibers that are used to carry. One of the questions I get asked about regarding optical cable measurements is: "Why don't my OTDR and jacket length markings agree?" The answer depends on the type of cable being made. In the old days (when you and I were a lot younger) the normal procedure was for a loose tube cable to be. Optical Power: is measured in "dBm", or decibels referenced to one miliwatt of power. You measure absolute power to test transmitters or receivers and relative power to test loss. The biggest feature of this cable is that the diameter of the central part through which light passes, called the core, is very small.
