Just measure the fiber on the spool of cable with the OTDR, then look at the cable jacket for length markings to get the actual length of the cable from the printed markings at each end of the cable. Cable Length There are four ways to calculate the cable length. The method you use depends on what information you have from the field. The chosen method may vary among. Applications Engineering Note is the most accurate method for determining the sheath distance to an optical fiber fault. It accounts for any variations in excess fiber length due to the differences in cable design, manufacturing tolerances, etc. This procedure is pre erred since it does not. Lead-in fibers are useful to locate short distance faults and making loss/attenuation measurement in real time mode.
