The MS9710B can measure wavelength, power level and SNR for up to 300 DWDM channels. It can also be used for PMD and EDFA noise floor measurements
Tunable Laser Source Tracking
This internal function eliminates the need for an external controller to make measurements using an Anritsu TLS. Internal Light Sources
Optional SLD, white light, and reference wavelength light sources can be installed in the MS9710B to simplify measurements. Calibration with the built-in reference source is a one-button operation. L-Band Measurements
Option 15 improves wavelength accuracy, resolution, power level flatness, and linearity in the 1570 to 1620 nm L-band region.
