Keysight (Agilent) N4375B 20/26.5 GHz Single-Mode Lightwave Component Analyzer

The Agilent N4375B Lightwave Component Analyzer (LCA) tests 10G Ethernet, FCx8, FCx10 and FCx16 electro-optical components, with up to 20 or 26.5 GHz modulation range. It comes in two basic versions. The economic line is based on a PNA-L network-analyzer and is available as a 2 port system. The high end version is based on the new PNA-X and offers true balanced measurements, extended optical modulation index (OMI) and is available with 2 or 4 ports. Both versions have the same specifications up to 20 GHz. The PNA-X based LCA is calibrated up to 26.5 GHz.

*This is a Web introductory price for one calibration of the Keysight (Agilent) N4375B. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

Related Optical Terms and Definitions. For a complete list go to our  Terms and Definitions Page.

A change in the optical frequency caused by direct modulation of the laser. A chirp is a signal in which the frequency increases ('up-chirp') or decreases ('down-chirp') with time. In some sources, the term chirp is used interchangeably with sweep signal.

The extent to which optical power from one signal path is prevented from reaching another signal path.

Polarization Extinction Ratio
Polarization Extinction Ratio is the ratio of optical power in the slow axis of the polarization maintaining fiber to optical power in the fast axis within a specified wavelength range.

Sidemode Suppression Ratio
Sidemode Suppression Ratio is the ratio of average signal power to the optical power of the highest sidemode within a distance from 0.1 to 6 GHz to the signal’s optical frequency, expressed in dB.

Wavelength Stability
Wavelength Stability is the change of wavelength during given time span, expressed as ± half the span between the maximum and the minimum of all actual wavelengths.
