World-class optical performance

High Resolution & High Dynamic Range
The advanced monochromator achieves high wavelength resolution and high close-in dynamic range. With the sharper spectral characteristics of the monochromator, spectral signals in close proximity can be separated clearly and measured accurately.
High Sensitivity
Weak optical signals can be measured accurately and quickly.

Pulsed Light Measurement

Free Space Input

■Multimode and single mode fiber on the same OSA ■Small insertion loss variation at the input connector increases measurement repeatability. ■No damage connecting fibers because there is no physical contact. ■Supports SM, GI (50/125 μm, 62.5/125 μm) and large core fiber up to 800 μm.

Excellent efficiency

Fast SweepWith an advanced monochromator, faster electrical circuits, and noise reduction techniques, the AQ6373 achieves fast measurement speed even when measuring a steep spectrum from DFB-LD or DWDM signals, or when measuring a low power signal from a broadband light source.

Fast Remote Interface
    AQ6373 provides faster remote control and data transfer capability.
   100x    Ethernet interface is 100 times faster
     10x     GP-IB interface is  10 times faster
(compared with the conventional GP-IB used on Yokogawa AQ6317 series Optical Spectrum Analyzer)

Wide Span Sweep yet High Resolution
The 50,001 data sampling points expands measurement range in a single sweep while keeping a high wavelength resolution. This makes your measurements easier and more efficient than conventional systems that use a low number of sampling points and require multiple partial measurements to cover the complete wavelength range.

Easy to Keep Accurate

Ambient condition change, vibration and shock to an optical precision product, like an optical spectrum analyzer, will effect the optical components and eventually degrade optical performance.
Using standard functions, the AQ6373 can maintain its high optical performance within a couple of minutes so that you can quickly start a measurement.

Optical alignment function
 Automatically aligns the optical path in the monochromator using the built-in source to maintain high performance.
Wavelength calibration function
 Automatically calibrates the spectrum analyzer with an external light source, to ensure the wavelength accuracy.

Note. There are cases that the optical alignment and wavelength calibration function cannot correct optical performance.
Periodical calibration is also required.
