Request InfoFibercoreFibercore Ltd. has released two new spun fiber products suitable for use in polarimetric sensors, including AC and DC fiber optic current transformers for electrical power generation and distribution. The SHB Spun High Birefringence fibers preserve circular polarization and are therefore insensitive to thermal- or vibration-induced signal fade/drift, making them suitable for long- or small-diameter sensor coils. The SLB Spun Low Birefringence fibers are designed for short-length, large-coil-diameter Faraday-effect current sensors. They do not resist the optical effects caused by...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 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.com 4/1/2024Compact ROADMThe DCP-R-34D-CS from Smartoptics is a compact reconfigurable optical add/drop multiplexer (ROADM) for larger fiber optic networks.
