The 3R regenerator generates the original bit sequence, and a modulated electric signal be used for analyzing BER, where RIC is an indication of how many times a package from another unit of data must be retransmitted because of an error. This first door of 3R regenerator is the output sequence of bits, the second is NRZ signal modulated and last exit is a copy of the input signal. These three signs can be connected directly to the BER Analyzer, avoiding additional links between the transmitter and the receiver stage. When using the 3R Regenerator, no need for connections between the transmitters and the parser of RIC.
