Here, it is vital to fix all delays +introduced in the data transmission blocks on the transmitter and receiver sides. The length of the +optical cable between two nodes can be evaluated by measuring the round-trip time of a datagram. +A precision of few nanoseconds down to 20~ps using the well-established FPGA-based TDC technology +can be reached. \ No newline at end of file
