Spectral range that is optically amplified (usually
based on a 3-dB drop).

The bandwidth of an optical fiber is approximately
inversely proportional to its length with negligible
mode mixing and changing processes. The bandwidth
multiplied by the length is therefore almost constant.
The BLP is an important parameter for characterising
the transmission properties of multimode fibers.
With increasing length, the bandwidth decreases to
a lesser extent. Consequently, a modified relationship
applies to the BLP, in which a gamma factor is
introduced.

Additional loss caused by micro- or macro-bending.
An increased bend loss may be caused by the manufacture
of the cable or by poor cable routing.

Two different definitions:

1. Minimum radius of curvature by which a fiber can be bent without breaking.
2. Minimum radius of curvature by which a fiber can be bent without exceeding a certain predetermined attenuation value.

Propagation of optical signals in opposing directions
along one optical waveguide.

Property by which the effective propagation velocity
of the light wave in a medium depends on the orientation
of the light’s electrical field (state of polarisation).

Basic unit of information in digital transmission
systems. The bit is equivalent to the decision between
two states, 1 and 0. Bits are represented as pulses.
A group of eight bits is equal to one byte.

Transmission rate of a binary signal, also called the bit
repetition rate.
