WebCable length meters and TDR’s (time domain reflectometer) are very similar but do have differences. A cable length meter simply determines spooled length on uninstalled cables or wires. A TDR finds cable length plus where along the length of the cable there are faults. Sometimes a cable may not have a complete break. WebWhen testing the fiber-optic plant, An optical power meter is used to measure the strength of light signals anywhere in a fiber system where a connection can be made. As changes are introduced to a fiber-optic network, Documentation must be updated to reflect the new configuration and performance data. As-built.
