Fastest Wavelength Measurement For WDM Testing Applications

The new 828B Optical Wavelength Meter measures absolute wavelength at a rate of 1 kHz.

Bristol Instruments, Inc., the leader in laser wavelength measurement technology, has set a new standard for WDM wavelength testing with the introduction of the 828B Optical Wavelength Meter. The model 828B provides the reliable accuracy that is expected from Bristol Instruments, and at a rate that is 100 times faster than any other system available.

The 828B Optical Wavelength Meter measures the absolute wavelength of WDM lasers to an accuracy of ± 1 pm. This accuracy is maintained over long periods of time by calibrating with a built-in wavelength standard resulting in a confidence level of 99.7%. Such performance should be familiar because it is the same as Bristol’s 228B Optical Wavelength Meter, 328B Optical Wavelength Meter, and 428B Multi-Wavelength Meter. What makes the 828B system so special is that it measures wavelength at a rate as high as 1 kHz. This speed is very important to manufacturers of WDM components because it enables more efficient wavelength testing and therefore greater productivity. What’s more, the speed of the 828B system provides time resolution as short as 1 ms, resulting in more detailed wavelength characterization of components such as tunable WDM lasers.

“Our customers have been asking for faster wavelength measurement for quite some time,” said Dr. Brian Samoriski, President of Bristol Instruments. “The 828B Optical Wavelength Meter satisfies this requirement demonstrating our commitment to our customers and our leadership in wavelength measurement technology.”
