Request InfoTerahertz Technologies Inc.Terahertz Technologies Inc. has unveiled a fiber optic probe for lab and field use. The TIA-950i mounts on the BNC input of an oscilloscope and reproduces the optical signal from the oscilloscope screen. It runs on a 9-V lithium battery and can detect 900- to 1700-nm wavelengths. It has a gain selection switch and a peak response value of about 1200 to 12,000 V/W. Applications include checking the output of a telecommunications or data link, the operation of a laser source and the signal from an optical transmitter.See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 5/17/2023Touchless Fiber Optic CleanerThe Sticklers™ Pro360™ Touchless Cleaner from MicroCare LLC is designed to quickly and efficiently remove oils and dust across the entire end face surface of both male and female...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 3/26/2024Intra-Data Center OpticsThe ICE-D series from Infinera are a line of high-speed intra-data center optics based on monolithic indium phosphide PIC technology.
