Request InfoNP Photonics Inc.NP Photonics says that its optical performance monitoring module combines high accuracy with an industry-standard platform. Based on the company's compliant MEMS Fabry-Perot tunable filter, the device measures optical signal-to-noise ratio at 50 GHz to >25 dB with accuracy better than ±0.5 dB. It features an integrated wavelength calibrator that provides absolute wavelength accuracy of ±15 pm and a single detector that covers the C- and L-bands with resolution down to 2 pm. To facilitate integration, the module fits into a 220 X 110 X 32-mm package and has a dual-port RAM...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra August 2022 IssueTime-of-Flight CameraThe DepthVista time of flight (ToF) camera from e-con Systems Inc. features a ToF depth sensor for depth measurement and the onsemi AR0234 color global shutter sensor for object identification. ...Photonics.com 12/12/2022Optical Sensing InterrogatorsFemto Sensing International has expanded its SX line of optical sensing interrogators for high-sensor-count fiber Bragg grating (FBG) applications.
