WAVEANALYZER™

WaveAnalyzer 400A

Optical Spectrum Analyzer

The WaveAnalyzer 400A is a compact Optical Spectrum Analyzer for

testing optical signals in the C-, in the Super C- and in the C+L band of

optical communications. The instrument has been designed for Research

& Development purposes as well as for Production Applications.

• The WA 400A uses coherent detection technology and can display the

x- and the y-Polarization separately.

• The instrument is very compact with only half a rack width and a height

of 1U.

• The detachable sub-panel on the front allows easy cleaning of the

internal connector.

The WA 400A can be connected through an Ethernet port to Local Area

Networks and allows signal monitoring and data gathering or simply

remotely controlling either via the internal webserver which can be

accessed by any browser or through the integrated RESTful Application

Programming Interface (API). The WA 400A supports both acquiring the IP

address through DHCP and setting a fixed address.

50 GHz spaced 10G DWDM channels modulated with a PRBS of 231-1 bits.

The high resolution capability of the WA 400A allows accurate measurement

of the noise floor between the channels.

The WA 400A integrates with Coherent’s well-known

WaveAnalyzer PC software. This package offers a variety

of analysis functions including Optical Signal to Noise

Ratio (OSNR) measurement, Side Mode Suppression

Ratio (SMSR) measurement, Multi-Channel (WDM-)

Analysis, Peak detection, etc.

The WA 400A offers a resolution bandwidth down to

650 MHz (Full Width Half Maximum). This allows display

of fine spectral details like modulation sidebands as well

as measurement of the noise floor between densely

spaced channels – as shown in the measurement trace

below. The coherent detection technology of the instru-

ment provides separate measurements of the x- and the

y-polarization – supporting analysis of dual polarization

transmission schemes.
