This section provides answers to some of the most frequently asked questions that we receive regarding the technologies used in the manufacture of our products. It has been developed to help our customers make an educated decision when purchasing fiber optic components. We welcome and encourage feedback on any of these topics, which we will incorporate into the forum, where appropriate.

If you have any questions you would like answered or any clarifications or additions you want to make to existing topics, please send your inquiries to the email address at the bottom of each topic page.

  • Many optical system designers are selecting micro-electro-mechanical systems (MEMS) based Variable Optical Attenuators (VOA). Why should I consider using liquid crystal based VOAs instead?
  • Liquid crystal based VOAs may be more reliable than MEMS based VOAs, but aren’t they incapable of handling high power input?
