Short-Reach Singlemode Puts Reflectance on the Radar

By on • ( Leave a comment )

Insertion loss budgets have gotten tighter as we have moved from 10 to 40/100 Gig for multimode fiber applications. One would think that we can’t say the same for singlemode applications that have historically meant larger loss budgets – 6.3 dB for 100 Gig over singlemode (100GBASE-LR4) versus just 1.9 dB for 100 Gig over multimode (100GBASE-SR4). But that’s no longer the case with new short-reach singlemode applications. And it’s not just insertion loss that matters with these applications; you now need to also be concerned with reflection.

Choosing to Deploy Single-mode or Multimode Fiber is Similar to Flying or Driving for Vacation

Believe it or not, choosing between deploying single-mode and multimode fiber optic cable is much like debating whether to drive or fly for a family vacation. How many people are going? What’s the fastest route? What will travel conditions be like? What’s your budget? How comfortable will we be on the trip? Do we need to bring extra luggage? Answering questions like these will help you choose whether you fly with singlemode fiber or drive with multimode.
