Standard and High-Performance Models

There are two models available, Standard and High Performance. The High performance model provides even higher wavelength accuracy and dynamic range.

High Wavelength Accuracy ±0.01nm

High performance model ±0.01nm (C band).
Standard model ±0.02nm (C + L band)

Wavelength Range	AQ6370C-10	AQ6370C-20
1520 nm to 1580 nm	±0.02 nm	±0.01nm
1580 nm to 1620 nm	±0.02 nm	±0.02 nm
1450 nm to 1520 nm	±0.04 nm	±0.04 nm
Full Range	±0.1 nm	±0.1 nm

Ultra-High Dynamic Range 78dB typ.

With the reduced stray-light in the monochromator, the AQ6370C achieves a typical ultra-high dynamic range of 78dB.

Unit	AQ6370C-10	AQ6370C-20
Peak ±1.0 nm	73dB	73dB (typ. 78dB)
Peak ±0.04 nm	62dB	64dB (typ. 70dB)
Peak ±0.2 nm	45dB	50dB (typ. 55dB)
*Resolution setting 0.05 nm*

Sharper Filter Edge

The high performance model can also achieve a higher dynamic range within 0.2nm of the peak wavelength. With the sharper spectral characteristics of the monochromator, spectral signals in close proximity can be separated clearly and measured accurately.

Unit	AQ6370C-10	AQ6370C-20
Peak ±0.2 nm	55dB	58dB (typ. 60dB)
Peak ±0.1 nm	37dB	45dB (typ. 50dB)
Resolution setting 0.02 nm

Stray-Light suppression ratio 80dB

Example of the stray-light suppression ratio

This new specification provides stray-light suppression when high dynamic mode, usually taking longer measurement time, is not used. The AQ6370 contributes to shortening the measurement time with the high stray light suppression ratio.

Wide Level Range +20dBm to -90dBm

The AQ6370C can measure high power sources such as optical amplifiers and pump lasers for Raman amplifiers, and very weak optical signals as well. Measurement sensitivity can be chosen from seven categories according to test applications and measurement requirements.

Improved level sensitivity: -85dBm (1000 nm to 1300 nm).
Smoothing Function - Reduce noise on measured spectrum.
High dynamic mode - Obtain a better dynamic range by reducing the influence of stray-light, which is caused when the input is a strong optical signal.

Free Space Input

Multimode and single mode fiber on the same OSA.
AQ6370's low insertion loss for multimode fiber is also beneficial to maintain the excellent measurement efficiency.
Small insertion loss variation at the input
connector increases measurement repeatability.
No damage connecting fibers
because there is no physical contact.
APC level correction
The APC level correction function corrects the level offset caused by an insertion loss of angled PC connector.

Free Space Input

Excellent Efficiency

Fast Sweep: 0.2sec/100nm
With an advanced monochromator, faster electrical circuits, and noise reduction techniques, the AQ6370C 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.

OSNR Measurement on DWDM System
DWDM channels allocated at 50GHz spacing
can be measured and analyzed

Optical Amplifier (EDFA) Measurement

WDM OSNR Test

AQ6370C's wide close-in dynamic range allows accurate OSNR measurement of DWDM transmission systems. The built-in WDM analysis function analyses the measured waveform and shows peak wavelength, peak level and OSNR of WDM signals up to 1024 channels simultaneously. The curve fit function is used to accurately measure noise levels.
