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 Time
Average time for the wave train to lose its phase realtionships

Fiber Bragg Grating (FBG)
A fiber Bragg grating (FBG) is a type of distributed Bragg reflector constructed in a short segment of optical fiber that reflects particular wavelengths of light and transmits all others. This is achieved by adding a periodic variation to the refractive index of the fiber core, which generates a wavelength specific dielectric mirror. A fiber Bragg grating can therefore be used as an inline optical filter to block certain wavelengths, or as a wavelength-specific reflector.

Modulation
Modulation is the process by which the characteristic of one wave (the carrier) is modified by another. Adding information into pulses of light.

Power Linearity
When changing the power level and measuring the differences (in dB) between actual and displayed power levels, the power linearity is ± half the span (in dB) between the maximum and the minimum value of all differences.

Stability
Stability is the extent to which a specified property, characteristic, or parameter of a substance, device, or apparatus, such as a fiber optic transmission system, remains fixed with the passage of time or with varying environmental conditions.
