From the first submarine...Photonics HandbookOTDRs: Finding the Weak Spots in Fiber Links: The optical time-domain reflectometer (OTDR) is used to characterize a fiber optic span. It performs single-ended tests and can calculate fiber attenuation and uniformity and splice and connector losses. It can also locate breaks and determine fiber length. Its ability to locate and measure reflectance and loss makes it the troubleshooting and fault locating equipment of choice. New generation OTDRs include advanced functions such as macrobend location, active-fiber testing and automatic trace acquisition.An optical time-domain reflectometer sends short pulses of light into a fiber and measures its reflections as a function of time. The delay of these reflections to the detector as well as their...Photonics HandbookWHITEPAPERSAccelerating Photonic Simulations with the Effective Index Method in RSoft ToolsThe Effective Index Method (EIM) can be used in Synopsys RSoft™ photonic design software to greatly reduce the computation time and memory requirements of a simulation by converting a 3D structure...Photonics.com 3/1/2018Optimal Lighting Design Boosts Efficiency of Medical Diagnostic InstrumentsWhen it comes to clinical diagnoses, light is the key to prediction accuracy and to making progress in analytical quality.
