What are the measurement methods for 10 Gigabit multimode fiber optic cables

As fiber deployments become commonplace, network owners and technicians are paying more attention to the two crucial devices for testing fiber optical cables: the Optical Loss Test Set (OLTS) and the Optical Time Domain Reflectometer (OTDR). An OLTS provides the most accurate insertion loss. Testing fiber optic components and cable plants requires making several measurements with the most common measurement parameters listed in the Table below. The method shown is on the FOA "1 Page Standard" FOA1 which you may print or download and insert in your documentation. EF is a method of characterizing the launch conditions of a multimode light source such as an LED or laser.
