The 81606A tunable laser source is a cost-effective module for the 8164B optical wave measurement system. It achieves high accuracy and increased test efficiency by providing faster scanned wavelength testing and lower cost of ownership.
It enables faster automatic adjustment of wavelength-selective devices by providing sub-pico repeatability and superior accuracy, as well as a bidirectional scan mode with scan speeds up to 200 nm/s.
Compared to the previous generation 81600B laser source, which maintained its leading edge for more than a decade, the 81606A tunable laser source offers greatly enhanced capabilities to help developers, designers and manufacturers of optical components accelerate test execution and improve test margins. Features include.
Significantly increased signal power and minimized spontaneous emission through the application of a new cavity and laser module design, resulting in a 15 dB increase in dynamic range
Innovative wavelength reference unit helps improve real-time tracking speed and resolution, increasing absolute measurement accuracy by a factor of 4
Enhanced feedback control and drive mechanisms allow scanning speeds up to 200 nm/s without compromising specified dynamic accuracy.
The 81606A tunable laser source is supported by the N7700A optical communications application software suite and, when used in conjunction with power meters and polarization instruments, allows measurement of spectral characteristics such as insertion loss, polarization-dependent loss, and dispersion. They provide excellent scanning wavelength accuracy and dynamic range.
For a more compact model, also consider the new N7776C tunable laser source.
