What is the minimum bit error rate for optical modules
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.
