Definitions for "Insertion Loss"
A measure of the attenuation of a device by determining the output of a system before and after the device is inserted into the system.
The loss caused by the inclusion of a splice, connector or other such component in a system.
One of the test parameters used when testing Category 5E or Category 6 UTP, FTP or ScTP Permanent Links or channels. Formerly known as attenuation, insertion loss is a measurement of the loss of signal over a length of cable. Whilst you will seldom get a fail condition here, it is important to note that a factor that could influence IL is excessive heat – watch out for cable runs in ceilings close to the external roof or anywhere near heat emitting devices. For Insertion Loss, the smaller the loss in decibel (dB), the better the performance.
