Standards Update

IEC 61280-4-1: Fibre-optic communication subsystem test procedures -  Part 4-1: Installed cable plant - Multimode Attenuation Measurement

On May 15th 2009 voting closed on IEC 61280-4-1. The standard was approved unamimously and therefore it will go forward for publication. It should be available to the public in a few weeks.

The standard gives new target and tolerance values for the source modal launch conditions required to measure loss in installed cable plant. These values are defined in terms of Encircled Flux.  

The good news is that its easy to comply with this requirement - use a ModCon.
