Request InfoLightwaves2020 Inc.The compact optical channel monitor released by Lightwaves2020 Inc. performs real-time nonintrusive measurement of optical channel power, wavelength and signal-to-noise ratio. Based on proprietary micro-optics and optical thin-film technology, it can scan the C-, L- or C+L bands sequentially and measure/monitor the optical channel power and wavelength at ITU grids of 100 or 50 GHz. Absolute and relative prechannel power accuracy are ±1 and ±0.5 dB, respectively. Absolute wavelength accuracy is ±100 pm. Polarization-dependent loss is 0.3 dB, optical return loss is 45 dB, and maximum adjacent...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 3/3/2023Wideband Telemetry ModelThe UWB-OCM ultra-wideband telemetry module from Coherent Corp. is an optical channel monitor designed for next-generation C+L-band optical transport systems.
