Erbium-doped
Fiber Amplifier (EDFA)
|
Optical
fibers doped with the rare earth element, erbium,
which can amplify light in the 1550 nm region when
pumped by an external light source. |
| Extrinsic
Loss |
In
a fiber interconnection, that portion of loss not
intrinsic to the fiber but related to imperfect
joining of a connector or splice. |
| Eye
Pattern |
Also
called eye diagram. The proper function of a digital
system can be quantitatively described by its BER,
or qualitatively by its eye pattern. The "openness"
of the eye relates to the BER that can be achieved. |
