Estimating Cable Length With Otdr

OTDR optical cable length increased

In the outside plant, the fiber length measured by the OTDR will almost always be greater than the cable footmark length due to the excess fiber length (EFL) placed in cable to handle temperature variation (usually around 2-3% excess). Optical time domain reflectometry (OTDR) is at the heart of quality assurance in the fiber optic network. For municipal utilities, which are increasingly building and operating their own fiber optic infrastructures, the professional implementation of OTDR measurements is becoming a decisive success. Frequently Asked Questions On OTDRS And Hints On Their Use OTDRs, also known by their technical name optical time domain reflectometers, are valuable fiber optic testers when used properly, but improper use can be misleading and, in our experience, lead to expensive mistakes for the contractor. It can verify splice loss, measure length and find faults. Later, comparisons can be made. also depends on the type of network to be characterised (overall length, density of optical devices). These pulses travel down the fibre and reflect when they encounter inconsistencies, like breaks, splices, or bends.
