Request InfoDiCon Fiberoptics Inc.DiCon Fiberoptics has announced a new tunable optical filter module for the GP750, a fiber optic test system that is able to automate fiber optic switches, fiber optical variable attenuators and, now, tunable optical filters. Based on proprietary microelectromechanical systems technology, the tunable filter can be tuned to demultiplex a signal in either the C- or L-band with a channel spacing of either 50 or 100 GHz. The tunable filter technology allows for precise wavelength tuning and is suitable for test applications in optical channel performance monitoring, reconfigurable optical...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra August 2023 IssueFiberscopesThe L-Series of rigid industrial-grade micro fiberscopes from Titan Tool Supply Inc. are fiber optic borescopes designed for remote visual inspections and diagnostics in hard-to-reach areas without...Photonics.com 4/2/2024Optical Transport SolutionsThe optical transport solutions from Nokia are meant for optical transport, IP routing, and PON applications and include coherent optical transceivers, a photonic engine, and a multihaul transceiver....Photonics.com 8/4/2022Fiber Optic ConnectorsThe Amphe-Lite connector series from Amphenol Industrial Operations has been enhanced to meet the needs of fiber optic interconnection applications in the medical, oil and gas, security, and grid...Photonics Spectra December 2023 IssuePluggable Optical Channel MonitorThe QSFP OCM (optical channel monitor) from PhotonPath, in collaboration with Jabil, is a pluggable optical channel monitor on a quad small form factor pluggable (QSFP) form factor created as a...ARTICLESPhotonics.com 8/18/2022Clinicians Turn to Unobtrusive Sensors for Patient MonitoringResearchers at the University of South Australia developed a multimode optical fiber (MMF) sensor array to unobtrusively monitor the movement and vital signs of patients in hospitals and other health...Photonics Spectra August 2022 IssueSelf-Cleaning Optical Fiber Generates Supercontinuum Light SourcesResearchers at Tampere University collaborated with colleagues at the University of Warsaw and the University of Burgundy France-Comté to create a supercontinuum light source in the...Photonics Spectra March 2024 IssueTeam Deepens Understanding of IC-PIC Integration's Thermal PenaltyCo-packaged optics for high performance computing and other data center applications require dense integration of silicon PICs with electronic integrated circuits (EICs).
