Customized Dispersion Compensation

Dispersion is a fiber based physical effect that spreads the optical pulse while it travels down the optical fiber. This effect worsens the signal quality and thus limits the maximum distance you can achieve with your optical system. In order to counter this effect, dispersion compensation modules are typically used.

Three different technology types (DCF, FBG, GT) can be customized to meet specific application needs.

Questions & Answers

Ask a question

  • Q:

    How to know the compensation length for my link? What is the math for that? By Karnes on December 06, 2017


    You can use the following method to calculate the compensation length, as a reference to select the DCM you need. The link distance minus the transmission distance of the optical module is the minimum compensation distance, on this basis need to add 20km to ensure enough compensation. For example, if the transmission span is 135km, the compensation length is 75km (135km - 80km + 20km = 75km), which means you can choose a DCM whose compensating length is 80km.
