Electromagnetic Interference (EMI): Noise generated when stray electromagnetic fields induce currents in electrical conductors (fiber is immune to EMI).

Jumper Cable: A short fiber cable with connectors on both ends used for interconnecting other cables or for testing.

Loss: Attenuation of optical signal, normally measured in decibels. The amount of a signal’s power, expressed in dB, that is lost in connectors, splices, or fiber defects.

The Epoxy and Polish style connectors represent the largest segment of connectors in both numbers being used as well as the number of styles available. These were the original connectors used in fiber optics. The styles include ST, SC, FC, LC, D4, SMA, MU AND MTRJ. The biggest advantage is that this style of connector accepts the widest assortment of cable jacket diameters. Most of the connectors noted above will fit onto 900um-buffered fiber, and up to 3.

The Pre-Loaded and No-Epoxy & Polish connectors require less skill but don’t necessarily reduce the time or equipment needed to do an installation. This type of connector includes the ST, SC and FC connectors. The Pre-Loaded connectors are just that, pre-loaded with a measured amount of epoxy. The second category, just like it says, uses no epoxy at all. This connector uses an internal crimp mechanism to hold the fiber in place. The benefits of using these, are that no epoxy injection is required at all.
