Question

Calculate the receiver sensitivity at a BER of $10^{-9}$ and $10^{-12}$ by using Eq. (6.5.16). Assume that the receiver operates at $1.55 \mu \mathrm{m}$ with $3-\mathrm{GHz}$ bandwidth. The preamplifier has a noise figure of 4 dB , and a 1-nm optical filter is installed between the preamplifier and the detector.

Instant Answer

Step 1

We have the following parameters: - Wavelength (\(\lambda\)) = \(1.55 \, \mu m\) - Bandwidth (\(B\)) = \(3 \, GHz = 3 \times 10^9 \, Hz\) - Noise figure (NF) = \(4 \, dB\) - Optical filter bandwidth = \(1 \, nm\) - Bit Error Rates (BER) = \(10^{-9}\) and Show more…
