Question
With reference to the power budget, what is the meaning of receiver dynamic range?
A. It is the minimum power to be received for a given BER.
B. It is the range between the receiver overload power and its sensitivity.
C. It is the range between the maximum transmit power and the minimum transmit power.
D. It is the maximum receiver power to prevent an overload.
Answer
B. It is the range between the receiver overload power and its sensitivity.
Explanation
In the context of a power budget, the receiver dynamic range refers to the range of optical power levels that a receiver can handle effectively. This range spans from the receiver’s sensitivity, which is the minimum power required to maintain a specified bit error rate (BER), up to the receiver overload power, beyond which the receiver’s performance degrades significantly.
Key points:
- Receiver sensitivity: The minimum power level required for the receiver to operate at a given BER.
- Receiver overload power: The maximum power level the receiver can handle without performance degradation.
- Dynamic range: The difference between the receiver overload power and sensitivity, typically expressed in decibels (dB).
A wider dynamic range allows the receiver to handle a broader range of incoming signal power levels without experiencing overload or degraded performance.
The other options are incorrect because:
A. Refers only to the receiver sensitivity, not the dynamic range.
C. Describes the transmitter power range, not the receiver dynamic range.
D. Mentions only the receiver overload power, not the full dynamic range.
