Is a lower RX value for optical modules always better
RX Sensitivity is the minimum optical power the receiver needs to correctly interpret a signal, expressed in dBm. Better (lower) RX sensitivity means you can tolerate weaker signals and longer fiber spans, but it also makes the system more susceptible to noise if the link is poorly. 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). This value is typically used in optical link budgeting to ensure. The key to a reliable connection is understanding three core metrics that SFP modules expose: transmit (TX) power, receive (RX) sensitivity, and the resulting optical budget.
