This article explores the many ways to achieve that goal.Just as an electronic connector provides a pluggable connection between electronic circuits, a fiber optic connector provides an optical one. The goal is joining a fiber to a transmitter, receiver or...Photonics HandbookPolarization in Fiber Systems: Squeezing out More Bandwidth: To appease the demand for bandwidth, telecommunication operators are pushed to increase the per-channel data rate of wavelength division multiplexing (WDM) systems.As bit rates increase to meet expanding demand, systems have become increasingly sensitive to polarization-related impairments. These include polarization mode dispersion (PMD) in optical fibers,...Photonics HandbookAdhesives for Fiber Optics Assembly: Making the Right Choice: Using the proper adhesive in the assembly of fiber optic components not only saves time and expense, but also can improve reliability and performance.Adhesives for fiber optic components that perform well on glass, metal, ceramic and most plastic substrates provide excellent chemical and solvent resistance. They also can act as an electrical...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...WHITEPAPERSPhotonics.com 9/4/2020Recent Research Using Meadowlark Optics Spatial Light ModulatorsThis ever-evolving collection of recent research using Meadowlark Optics Spatial Light Modulators offers a brief overview of specific applications in which Meadowlark Optics’ Spatial Light Modulators...Photonics.com 6/3/2020Robust 785 nm lasers for Raman by CoboltHÜBNER Photonics is one of the leading suppliers of all laser wavelengths to the high resolution Raman spectroscopy market and now introduces the 08-NLDM 785 nm ESP (enhanced spectral purity) as part...WEBINARSPhotonics.com 6/2/2020Upgrade Your Fiber Optic Diagnostics with Portable Ultrahigh-Resolution Optical Backscatter ReflectometryOptical backscatter reflectometry (OBR) has become a valuable tool in the testing and diagnostics of fiber optic assemblies, components, and short networks.
