Request InfoEXFO Inc.QUEBEC CITY, Jan. 28 -- Exfo Electro-Optical Engineering Inc. has introduced its FTB-7200D four-wavelength optical time domain reflectometer (OTDR) for the premises network and cabling installation markets. This unique OTDR, a single-slot module housed in either the FTB-400 or FTB-100B field-testing platforms, characterizes both multimode and singlemode fiber on as many as four wavelengths. It boasts the shortest dead zones in the industry: event dead zone of =1 m and attenuation dead zone of =4.5 m (3 m at 850 nm) for both multimode and singlemode fiber. In addition, it offers a high dynamic...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 4/27/2023Optical Time Domain ReflectometersThe D-Series of Optical Time Domain Reflectometer (OTDR) solutions from EXFO are advanced field testing tools that deliver highly accurate measurements to characterize and validate fiber links. ...Photonics Spectra July 2023 IssueCombination DWDM and OTDRThe RXT-4113+ combination dense wavelength division multiplexing (DWDM) and legacy optical time domain reflectometer (OTDR) from VeEX Inc. is designed for contractors and technicians who require...Photonics Spectra February 2023 IssueDual-Port Test SolutionThe FTBx-88480 dual-port test solution from EXFO Inc. enhances technician productivity for fiber optic transmission rates from 1 to 400 G.
