Glossary

Tunable Laser Source

Glossary

Alternating current

adapter

A device for coupling two connectors.

amplifier

A device used to boost the strength (dB level) of a signal.

amplitude

The distance between high and low points of a waveform or

signal.

ASCII

American Standard Code for Information Interchange. A

system used to represent letters, numbers, symbols, and

punctuation as bytes of binary signals.

ASE

Amplified Spontaneous Emission. Light emitted from the

decay of the upper level of a lasing transition without

stimulated emission. In general, this emission is spectrally

broad and unpolarized.

attenuation

The diminution of average optical power. Attenuation results

from absorption, scattering, and other radiation losses.

Attenuation is generally expressed in dB without a negative

sign.

attenuation
coefficient

A factor expressing attenuation per unit length, expressed in

dB/km.

attenuator

An optical device, either fixed or adjustable, that reduces the

intensity of light propagating through it.

axis of birefringence

One of two generally orthogonal orientations transverse to

the fiber core corresponding to fast and slow propagation of

the group velocity of a light beam. In general, these

orientations are elliptical and the orientation and amplitude

vary along the fiber. In the special case of a HiBi fiber, the

axes are linear and constant along the length of the fiber.

fib

Fiber bandwidth, normally dependent on carrier wavelength

and fiber length.

opt

Optical bandwidth
