Keysight (Agilent) 81940A 1520 to 1630 nm Compact Tunable Laser Source Module

The Agilent 81940A high power compact tunable laser enables optical device characterization at high power levels and measurement of nonlinear effects. It improves the testing of all types of optical amplifiers and other active components as well as broadband passive optical components. As single slot plug-in modules for Agilent's 8163A/B, 8164A/B and 8166A/B mainframes, they are a flexible and cost effective stimulus for single channel and DWDM test applications. Each module covers a total wavelength range of 110 nm in the C+L-band.

Coherence Length
Average distance over which superimposed waves lose their phase relationships

Linewidth
Linewidth is the width of a spectral line in terms of wavelength, wave number and frequency.

Power Flatness Versus Wavelength
When changing the wavelength at constant power setting and recording the differences between actual and displayed power levels, the power flatness is ± half the span (in dB) between the maximum and the minimum of the measured power levels.

Spectral Width
Spectral Width is the wavelength interval over which the magnitude of all spectral components is equal to or greater than a specified fraction of the magnitude of the component having the maximum value. In optical communications applications, the usual method of specifying spectral width is the full width at half maximum. This is the same convention used in bandwidth, defined as the frequency range where power drops by less than half (at most -3 dB).

Telecom Bands
Optical fiber communications typically operate in a wavelength region corresponding to one of the following Bands. O Band (original): 1260–1360 nm. E Band (extended): 1360–1460 nm. S Band (short wavelengths): 1460–1530 nm. C Band (conventional): 1530–1565 nm. L Band (long wavelengths): 1565–1625 nm. U Band (ultralong wavelengths): 1625–1675 nm
