Receiver sensitivity refers to the minimum average input optical power that the receiver component of an optical module can detect while achieving a specified BER, often 10⁻¹² for high-speed systems like Gigabit Ethernet or Fibre Channel . It is a critical parameter because if the received optical power falls below this threshold, the module may fail to decode signals correctly, resulting in increased bit errors . Conversely, if the received power exceeds the overload limit, signal distortion can also occur .
Sensitivity is measured in dBm, representing the optical power level at which the receiver can operate reliably under controlled laboratory conditions . The measurement typically involves plotting a BER versus received optical power curve, where the sensitivity corresponds to the minimum power at which the BER meets the standard requirement . Some high-speed modules also specify stressed receiver sensitivity, which tests the receiver under intentionally degraded signals to simulate real-world impairments like jitter or eye closure .
Several factors influence receiver sensitivity:
Receiver sensitivity is essential for optical link budgeting, ensuring that sufficient optical power reaches the receiver after accounting for fiber losses, connectors, and other impairments . Using the sensitivity value alone may underestimate link loss tolerance, so designers often rely on minimum receiver power specifications, which include margins for worst-case conditions . Proper understanding of sensitivity ensures reliable operation, minimizes bit errors, and supports interoperability across different optical modules and network equipment .
