Keysight (Agilent) N4373D 43.5/50/67 GHz SM Lightwave Component Analyzer, 40/100G EO T

The Keysight N4373D Lightwave Component Analyzer offers the latest N5227A series network analyzers with 2-port or 4-port configuration. This LCA, based on the new N522xA PNA Microwave Network Analyzer series offers a modulation bandwidth of 43.5/50/67 GHz which makes it the ideal choice to develop and characterize electro-optical components, for 40G/100GbE and the upcoming 400G and 1 Tbit/s transmission systems. It is the ideal test instrument for electro-optical components for 56 Gbaud coherent transmission, as well as Radio over Fiber (RoF) and aerospace and defense (A&D) electro-optical test applications. Measurement capabilities; 3 dB cut-off frequency (S21), Responsivity (S21), Electrical reflection (S11 or S22), Group Delay vs. frequency, Insertion Loss (IL), Transmission bandwidth, Differential and common mode parameters with 4 channel PNA, All electrical S-parameter measurements.

*This is a Web introductory price for one calibration of the Keysight (Agilent) N4373D. 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.

Broadband Source (BBS)
A Broadband Source is a spectrally large source that emits a signal which contains a continuous range of frequencies with a broad optical bandwidth (usually 100 nm or more). Sometimes called a white light source, there are two different meanings of this term. Visible white light and a source which does not necessarily emit in the visible spectral region.

Coherence
Coherence is the pattern and or relationships of waves due to phase properties.

Linearity
Linearity is the relative difference between the displayed power ratio, Dx/D0, and the actual (true) power ratio Px/P0 caused by changing the displayed power level from the reference level, D0, to an arbitrary displayed level, Dx.

Power Flatness Over Modulation
When changing the wavelength and modulation frequency, and measuring the differences between actual and displayed power levels (in dB), the power flatness is ± half the span between the maximum and the minimum value of all differences.

Singlemode fiber
Singlemode Fiber has a small core, only about 9 microns, and is used for telephony and CATV with laser sources at 1300 and 1550 nm. It can go very long distances at very high speeds. Both multimode and singlemode fiber have an outside diameter of 125 microns - about 5 thousandths of an inch - just slightly larger than a human hair.
