Bristol Instruments offers 828A Optical Wavelength Meter for CW and modulated optical signals

Bristol Instruments, Inc. displayed its 828A Optical Wavelength Meter for the first time at OFC 2018 in San Diego last week. The meter measures the absolute wavelength of CW and modulated optical signals. The 828A Optical Wavelength Meter uses a Fizeau etalon design to measure laser wavelength to an accuracy as high as ± 0.3 pm, and provides the fastest available measurement rate, Bristol attests.

The 828A has a sustained measurement rate as high as 1 kHz, enabling a test time reduction from hours to minutes. The speed of the system also offers a time resolution of 1 ms to deliver more detailed wavelength characterization of tunable WDMlasers and other components, asserts the company.

With straightforward operation, the 828A model has a touch-screen display that reports measurement data in various formats. By calibrating to a built-in wavelength standard, system performance is maintained over long periods of time.

"We strive to provide our customers with precision instruments for WDM testing that greatly improve the efficiency of their manufacturing processes," said Dr. Brian Samoriski, Bristol's vice president of sales and marketing. "With the unmatched speed and highest accuracy of the new model 828A, we can help them achieve this result."

Bristol is headquartered in Victor, NY. The company's latest wavelength meter offering follows its 2016 introduction of the 871 Series Laser Wavelength Meter to measure absolute wavelength of pulsed and CW lasers (see "Bristol Instruments offers fast wavelength meter for pulsed lasers") and its 438 Series Multi-Wavelength Meter, measuring the wavelength, power, and OSNR of up to 1000 discrete optical signals, in 2017 (see "Bristol Instruments 438 Series Multi-Wavelength Meter supports 10 Hz measurement rate").
