Technical Article: Fiber Bragg Grating Dispersion Compensation Enables Cost-Efficient Submarine Optical Transport

By Fredrik Sjostrom, Proximion Fiber Systems

Undersea optical transport is an important part of the infrastructure making up the world-spanning digital transport network. Due to extreme link length and stringent reliability requirements, this important part of the optical backbone poses quite a challenge compared to the more conventional terrestrial systems hence specific technical solutions are required. This article discusses how the unique properties and design possibilities relating to Fiber Bragg Grating (FBG)-based dispersion compensation technology can facilitate desirable cost savings by supporting new terminal designs and link optimized compensations.
