Keysight N4375D
26.5 GHz Single-Mode
Lightwave Component Analyzer


Data Sheet
General Information

Keysight Technologies' N4375D Lightwave Component Analyzer (LCA) is the instrument of choice to
test 10G Ethernet, FCx8, FCx10 and FCx16 electro-optical components, with up to 26.5 GHz modula-
tion range as well as electro-optical components for 40/100GbE and 100 Gb/s coherent transmission.

Modern optical transmission systems require fast, accurate and repeatable characterization of
the core electro-optical components, the transmitter, receiver, and their subcomponents (lasers,
modulators and detectors), to guarantee performance with respect to modulation bandwidth, jitter,
gain, and distortion of the final transceiver.

The N4375D guarantees excellent electro-optical measurement performance through NIST traceable
factory calibration chain. In addition a unique new calibration concept significantly reduces time from
powering up the LCA until the first calibrated measurement can be made. This increases productivity
in R&D and on the manufacturing floor.

The fully integrated "turnkey" solution reduces time to market, compared to the time-consuming
development of a self-made setup.

The electrical and optical design of the N4375D is optimized for lowest noise and ripple. In addition,
this design makes the accuracy independent of the electrical reflection coefficient. It's the excellent
accuracy and repeatability that improves the yield from tests performed with the N4375D, by narrow-
ing margins needed to pass the tested devices. NIST traceability ensures world-wide comparability of
test results.

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

Using the advanced measurement capabilities of the network analyzer, all S-parameter related char-
acteristics of the device under test, like responsivity, ripple, group delay and 3 dB-cutoff frequency,
can be qualified with the new N4375D Lightwave Component Analyzer from 10 MHz to 25.6 GHz.

The network analyzer
The N4375D LCA is based on the new 2- and 4-port N5222A PNA Series microwave network analyzer
with an identical and well known user interface across all Keysight network analyzers. Versions
with configurable test set and bias-T integrated in the network analyzer are available. The High RF
output power ensures a higher optical modulation index (OMI). This gives you the freedom to change
between small signal analysis and large signal analysis of your device under test. True mode balanced
measurements are possible with 4-port, dual source network analyzers.
