Agilent Technologies Inc. has unveiled the fourth member of its lightwave component analyzer (LCA) series, claimed to be the only turnkey test solution for CATV or radio over fiber electro-optical component test. The LCA offers fast calibration and test setup, providing a time-saving, competitive edge to all design and manufacturing engineers.

The Agilent N4374B LCA replaces the 8702 LCA, and offers accurate and traceable electro-optical S-parameter for transmitter and receiver test and is based on the ENA-C series Agilent network analyzers.

In linear optical transmission systems, like CATV or in radio over fiber applications, the performance of the electro-optical components is a key contributor to the performance of the overall transmission system. The N4374B LCA enables design engineers to design electro-optical transmitters and receivers with lowest distortion by offering specified phase accuracy in addition to high-amplitude accuracy.

The Agilent N4374B LCA also offers first-time relative and absolute responsivity specification traceable to international standards. This ensures that all test data are worldwide comparable within the specified uncertainty, thus helping R&D and manufacturing engineers to compare test results measured with two LCA at different locations.

"Fast and accurate electro-optical test with a turn-key solution are key contributors for developing high-quality products with a reduced design cycle," said Juergen Beck, general manager of Agilent's digital photonic test business. "The lightwave component analyzer is the workhorse for designers and manufacturing engineers of electro-optical components because it offers the highest productivity, thanks to faster and easy calibration and test setup."

Additional features of the Agilent N4374B lightwave component analyzer include:

  • accurate responsivity test with less than 0.8dB uncertainty;

  • specified absolute accuracy of absolute responsivity;

  • 75? support with minimum loss pad for CATV applications;

  • specified phase uncertainty;

  • integrated optical average power meter; and

  • identical user interface and remote control across all new N437x LCA series.

    The Agilent N4374B lightwave component analyzer is available with single or dual wavelength options at 1,310- or 1,550nm. Pricing starts at $101,000.
