Ever increasing network speeds and tighter loss budgets ensure qualifying multimode fiber links remains a formidable challenge. Part of the challenge can stem from test instruments. In some scenarios different test instruments can produce different measurement results on the same network due to variations in launch conditions between test sources. The result is confusion and wasted time verifying actual measurement values. Wasted time means extended network downtime or delayed network starts. To help minimize test errors, standards bodies embraced encircled flux to better standardize multimode launch conditions.

Encircled Flux (EF) standards, TIA-526-14-B and IEC 61280-4-1 Ed. 2.0, define a method of controlling multimode launch conditions for optical test sources. More consistent test source launch conditions equate to more accurate and repeatable measurements. This is the goal driving the migration to encircled flux standards.
AFL OTDRs and Fault Locators

AFL OTDRs and Fault Locators

AFL optical time domain reflectometers (OTDRs) and fault locators are used to certify new fibre installations and locate faults in deployed fibre optic networks. OTDRs and fault locators are available for both multi-mode and single-mode networks, including FTTx PONs. OTDRs scan fibre optic networks from one end of the fibre, displaying a trace and reporting detected events such as splices, connectors, micro- or macro-bends and fibre end. Fibre length is reported along with location, loss and reflectance of detected events. Several OTDRs are available with an integrated visual fault locator (VFL), optical light source (OLS), and/or optical power meter (OPM). OTDR results can be saved and uploaded to PC for further analysis and/or archiving.
