DSPs simplify PMD Tolerance Testing of Coherent Receivers

New Ridge has been at the forefront in defining test methodologies and designing and manufacturing equipment to make PMD tolerance testing of fiber optical receivers quantitative, repeatable, and comparable. Our PMD sources have set the standard for the generation of PMD states to ease the often difficult and lengthy process of PMD testing. Then coherent Read more about DSPs simplify PMD Tolerance Testing of Coherent Receivers[…]

A Back-to-School OSA

In gratitude to the academics who push new frontiers of science and technology and train the next generation of scientists and engineers, we are announcing our 2016 ‘Back To School’ sale of the NRT-8000 compact OSA. For this limited time the NRT-8000 is priced below the normal academic discount. So academics, get a new Optical Spectrum Analyzer Read more about A Back-to-School OSA[…]

Are Ultrafast SOP Events Affecting Your Coherent Receivers?

I get a fair number of confidential phone calls and e-mails reporting coherent receivers unlocking due to very fast SOP transient events. These transients can be hundreds of thousands of radians per second, even over 1 million radians per second, within 10s of microseconds, followed by a slower relaxation in a few milliseconds. Such ∆SOPs Read more about Are Ultrafast SOP Events Affecting Your Coherent Receivers?[…]
