Minimum Receiver Power (sometimes referred to as Receiver Minimum Input Power) is the lowest level of optical power at which the module is guaranteed to operate without exceeding a specified bit error rate (typically BER ≤ 10⁻¹²). To perform a bit error rate test, a pre-defined data stream is sent through a network link input, then the output of the link at the receiving end is analyzed to. Bit Error Rate (BER) is a critical performance metric in optical communications that measures the number of errors occurring in a transmitted data stream over a certain period. It is defined as the ratio of the number of bits received in error to the total number of bits transmitted.
