Cable Testing 101 There's No Gain with Gainers

Description:

Akin to water flowing from a small pipe into a large pipe, gainers are essentially perceived increases in optical power that occur at splice points due to variations in fiber characteristics, including core diameter, numerical apertures, mode field diameters and backscatter coefficients. Since gainers can be a significant source of confusion for new optical time domain reflectometer (OTDR) users, let's take a look at why these occur, what impact they have and how to avoid them. – PowerPoint PPT presentation
