OPTICAL WAVELENGTH METER 828 Series
The fastest wavelength measurement available for optical transceiver testing.
The 828 Series Optical Wavelength Meter from Bristol Instruments is designed to revolutionize the production of tunable transmitter lasers used in WDM applications. This system uses a unique design to provide an unmatched measurement rate of 1 kHz. This enables greater effifi ciency in the production of WDM transceivers by dramatically reducing the time needed for wavelength testing. Two versions of the 828 Optical Wavelength Meter are available. The model 828A is the most precise, providing an accuracy of ± 0.3 pm. For less exacting test requirements, the model 828B is a lower-priced alternative with a wavelength accuracy of ± 1.0 pm. Automatic calibration with a built-in wavelength standard ensures the utmost confifi dence in the test results. The rugged design of the 828 Optical Wavelength Meter provides long-term reliable operation, backed by a fifi ve-year warranty on all parts and labor. This results in less downtime and the lowest cost of ownership available.
