Keysight (Agilent) N4373B 67 GHz Single-Mode Lightwave Component Analyzer

The Agilent N4373B Lightwave Component Analyzer (LCA) tests the most advanced 40 Gb/s electro-optical components, with up to 67 GHz modulation bandwidth. It achieves fast measurements by including an E8361A Performance Network Analyzer. In the N4373B, all optical and electrical components are carefully selected and matched to each other, to minimize noise and ripple in the measurement traces. Together with the temperature stabilization of the core components, this improves the repeatability and the accuracy of the overall system. It has the following measurement capabilities:
3dB cut-off frequency (S21),
Responsivity (S21),
Electrical reflection (S11 or S22),
Group Delay vs. frequency,
Insertion Loss (IL),
Transmission bandwidth (optical),
Transmission bandwidth (electro-optical),
all electrical S-parameter measurements.

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

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
