Enter Class 1 laser products — lasers that are so safe that the user doesn’t require specific laser safety training or protective eyewear. Some precautions still exist, though.When purchasing an industrial laser system, the astute buyer will look for a Class 1 laser product — a system where the laser beam hazard is completely enclosed and there is no potential laser...Photonics HandbookSpectrum Analysis for DWDM: New Instruments Meet the Challenge: The demand for bandwidth drives a growing need for a new breed of test and measurement instruments.As system and cable installers try to optimize their links, the preferred method has become high-speed DWDM. This demand for bandwidth has led to the development of new test and measurement...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 HandbookLaser Measurement Systems: Best Practices: When purchasing a laser, learning how to apply, troubleshoot, and evaluate that device is very important.Given the pace at which technology advances, there always seems to be a learning curve.
