US Patent 10985838 Handling compensation for losses in optical fiber links

Systems and methods for measuring accumulated power losses over a fiber link are described in the present disclosure. According to one embodiment, a method includes the step of measuring accumulated losses over a fiber link. The method also includes the step of at least partially compensating for the measured accumulated losses. In response to determining that there is a compensation shortfall with respect to the accumulated losses, the method includes the step of transmitting the compensation shortfall to one or more downstream controllers.
