EXCELLENT SIGNAL SEPARATION
|
|
The AQ6370B uses a newly developed high performance monochromator
to achieve high wavelength resolution (0.02 nm)
and wide close-in dynamic range (70 dB).
With the sharper spectral characteristics of the new monochromator,
OSNR measurement of 50 GHz spacing DWDM transmission systems
and EDFA evaluation with multiple wavelength sources
can successfully be performed.
|
Close-in Dynamic Range
70 dB at peak ±0.4 nm, resolution setting 0.02 nm (typical)
|
|
|
WIDE MEASUREMENT RANGE |
|
|
Power: +20 dBm to -90 dBm
The AQ6370B can measure optical power as high as +20 dBm,
which enables direct measurement of high power sources
such as optical amplifiers and pump lasers for Raman amplifiers.
Measurement sensitivity can be chosen from seven categories
according to test applications and measurement speed requirements.
|
|
|
Wavelength: 600 nm to 1700 nm
The AQ6370B covers not only telecommunication wavelengths,
but also the visible light wavelength region
which is used for home electronics, medical, and industrial material applications.
|
|
Level sensitivity settings;
NORM Hold, NORM Auto, NORM, MID, and HIGH (1, 2, and 3),
that correspond to sensitivity from -60dBm through -90dBm.
|
|
High dynamic range mode settings;
SWITCH mode is to obtain a better dynamic range
by reducing an influence of stray-light.
They are applicable in MID and HIGH mode.

|
MULTIMODE FIBER TEST CAPABILITY
|
|
The AQ6370B uses a free space input structure
that can handle up to GI 62.5/125 multimode fiber.
Multimode fiber is commonly used in high speed Ethernet network,
such as GE-PON.
The free space input is also beneficial for measurement repeatability
as insertion loss variation at the input connector is smaller than the other input type
which has an optical fiber inside the monochromator.

PULSED LIGHT MEASUREMENT CAPABILITY
|
|
|
The AQ6370B can catch the peak power of a pulsed signal
using PEAK HOLD or using an externally provided trigger
to synchronize with the measured signal.
It can be applied to the transmission loop testing of telecommunication systems,
and also to the low power measurement at the early stage of laser chip development
since it works in the high sensitivity modes.
