These include polarization mode dispersion (PMD) in optical fibers,...Photonics HandbookPhotonics Packaging: Optical Communication ComponentsAn examination of the packaging technology of photonic components for optical communication and other areas of photonics. Photonic components are key elements for the information technology (IT)....Photonics HandbookPolarization Mode Dispersion: Concepts and Measurement: The performance of high-speed, digital fiber optic communications systems depends upon how reliably the receiver is able to distinguish closely spaced bits of information. Dispersive effects — physical mechanisms that broaden transmitted pulses — degrade this process.There are three fundamentally different dispersive phenomena in optical fiber, of which polarization mode dispersion (PMD) is the most complex. In digital multimode fiber systems, a light pulse...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 HandbookPHOTONICS BUYERS' GUIDE CATEGORIESInGaAsP LasersCW CO2 LasersInGaAs LasersHigh-Voltage Power SuppliesCOMPANIESLaCroix Precision OpticsOptics that Defend, Build, Cure and Discover The LaCroix name is synonymous with quality precision optics.
