Caption
(a) Experimental setup illustrating the network layout and how the FPGA-based coherent transceiver prototype was
connected to the network for continuous monitoring/sensing. (b) A map of Sunet’s Swedish fiber network with the 524-km
route round-trip from Gothenburg to Karlstad and back highlighted in blue. (c) Zoom-in of the route consisting of aerial fiber,including five ROADM nodes, which were connected with the aerial cables using shorter segments of buried fiber. The fiber break happened as one of these segments was accidentally exposed by an excavator, with the approximate location illustrated by the star.
