Quadtech 7600 Data Sheet

Recent advances in dense wavelength-division multiplexing (DWDM) technology have resulted in the need for more sophisticated test and measurement
instrumentation. The ability to accurately measure optical wavelength is necessary in order to characterize and optimize DWDM components and DWDM
transmission systems.

While the wavelength performance of DWDM components can be characterized using conventional means such as WA-1650/1150
and WA-1100 Wavemeter

®

Optical Wavelength Meters, analysis of DWDM transmission systems requires instrumentation capable of
measuring the discrete wavelengths of the many optical carriers present on a single fiber. Such demands are addressed by the WA-7600
and WA-7100 Wavemeter Multiline Optical Channel Analyzers.

THE WAVEMETER ADVANTAGE

WA-7600 and WA-7100 Optical Channel Analyzers employ proven scanning Michelson interferometer-based Wavemeter technology
to determine the absolute wavelength of an optical signal under test by comparing its interference fringe pattern with that of a built-in HeNe laser wavelength
standard. Unlike other wavelength meters, all factors that can affect wavelength measurement are accounted for, ensuring the highest possible accuracy.
To ensure accuracy, all Wavemeter systems are traceable to recognized standards.

SIMULTANEOUS WAVELENGTH AND POWER MEASUREMENT

Combining proven scanning Michelson interferometer-based technology with advanced digital processing results in the ability to measure and differentiate the
absolute wavelengths of up to 256 discrete optical signals. The accuracy of these measurements is ± 0.2 ppm. What’s more, the WA-7600 can simultaneously
measure the individual powers of the optical signals. In addition to the WA-7600, EXFO also offers the WA-7100 Wavemeter Multiline Optical Channel Analyzer.
Identical to the WA-7600, it offers an absolute wavelength uncertainty of ± 1 ppm, providing a lower cost alternative.

HIGH-RESOLUTION OPTICAL SPECTRAL ANALYSIS

Unlike other multiwavelength meters, the WA-7600/WA-7100 provide the full optical spectrum on a clear, easy-to-read display for the
most precise DWDM channel analysis. Spectral resolution is as high as 30 pm, resulting in a narrow, sharp-edged spectral response. Discrimination between
closely spaced DWDM channels is easily achieved for current 100 GHz and 50 GHz channel spacing and future 25 GHz channel spacing.

AUTOMATIC CALCULATION INCREASES PRODUCTIVITY

The WA-7600/WA-7100 automatically process measurement data, providing critical DWDM system performance information. In addition to resolving the individual
optical carriers and accurately confirming their wavelengths and powers, the WA-7600/WA-7100 calculate parameters such as channel spacing and OSNR.

STABLE MEASUREMENT WITH RUGGED DESIGN

Stability of all measurements is ensured with the WA-7600/WA-7100 systems’ rugged benchtop or rack-mounted package.
