For example, a single mode OTDR with a dynamic range of 35dB has a useable dynamic range of about 30 dB. Assuming a normal fiber attenuation of 0. 20dB/km at 1550nm and splices every 2km (0. An Optical Time-Domain Reflectometer (OTDR) is an essential tool for fiber optic network testing, troubleshooting, and maintenance. 1 dB per splice), a unit such as this one will be able to accurately certify distances of up to 120. The OptiFiber Pro® Series OTDRs are the Tier 2 (extended) fiber certification solution for Datacenters, Outside Plant (OSP), FTTx and PON environments and are part of the Versiv™ Cabling Certification system. In comparison, a. Whether you are specifying a new OTDR and need to determine its maximum testing distance or just seeking to learn more about the topic of dynamic range, this popular tool will be beneficial.
