With Siemon Fiber, You Don’t Have to Compromise


At Siemon, we don’t believe that our customers should settle when it comes to their optical performance. That’s why we’ve developed our plug and play solutions in line with the most stringent industry standards, which allows our customers to have peace of mind that they will have the flexibility they need over a range of distances and configurations, all while remaining within their loss budget.

We like to keep things simple, so we only provide two performance options.

  1. Our Standard Loss components are in line with many other industry leaders’ “low loss” offerings, which means that our standard is the same as their “best”.
  2. Ultra-Low Loss (ULL) components offer the pinnacle of performance and provide you with the ideal foundation to support high bandwidth, low latency applications.
