N4373E 43.5/50/67 GHz Single-Mode/Multimode Fiber Lightwave Component Analyzer for 100G/400G/1T Electro-Optical Test

Keysight N4373E 43.5/50/67 GHz

Single-Mode/Multimode Fiber Lightwave Component Analyzer for 100G/400G/1T Electro-Optical Test

General Information

The Keysight N4373E Lightwave Component Analyzer (LCA), based on the new N52xxB series PNA Microwave Network Analyzers, 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, for 400 Gbit/s and for the upcoming 1 Tbit/s transmission systems.

Accuracy

For these modern optical transmission systems with advanced modulation schemes, it is key for the electro-optical components to have very flat S21 transfer function in amplitude and delay. This performance can be verified only with electro-optical Sparameter test as provided by the N4373E LCA.

In addition, fast, accurate, repeatable and traceable characterization of these electrooptical components, like lasers, modulators, detectors and integrated receivers is required, to guarantee the performance with respect to modulation bandwidth, jitter, gain, and distortion.

Electro-optical device manufacturers benefit from increased yield through narrower test margins because the LCA's electrical and optical design have been optimized for lowest noise and ripple, resulting in improved accuracy.

This advanced design together with temperature-stabilized transmitter and receiver ensures repeatable measurements over days without recalibration.

Turn-key solution

The fully integrated “turn-key” N4373E helps reduce time to market, compared to the time-consuming development of a self-made setup. In addition, you get a fully specified, easy transferable and reliable test instrument. With guaranteed specifications Keysight takes the responsibility to provide you with accurate and traceable test results that can only be achieved in a turn-key solution.

NEW! 850 nm multimode fiber solution up to 50 GHz bandwidth

With the latest option added to the N4373E, measurements of electro-optical components for multimode fiber in the 850-nm window are now enabled with launch conditions according to IEEE 802.3ae - 2002.

High productivity

The N4373E achieves fast measurements by including the N52xxB PNA Microwave Network Analyzer. A unique new calibration concept significantly reduces setup time to a maximum of several minutes, depending on the selected measurement parameters. This results in increased productivity in R&D or on the manufacturing floor.

Using the advanced measurement capabilities of the network analyzer, all S-parameter related characteristics of the device under test, like responsivity and 3 dB-cutoff frequency, can be qualified with the new N4373E Lightwave Component Analyzer from 10 MHz to 43.5/50/67 GHz.

Network analyzer

The N4373E LCA is based on the new N52xxB PNA Series network analyzer with an identical and well known user interface across all Keysight network analyzers.
