EECS 285AP FINAL EXAM
PROJECT

Problem statement
• You have 4 cities that needs to be connected by fiber. Your job is to design this
network. Each channel can be 2.5Gb/s or 10Gb/s OOK modulated lasers. If you
need amplification, you can place your amplifier at one of the sites where
electrical power is available.
• You need to have proper configuration to drop the relevant channels and add
new channels to the system.
• The SNR at the receiver has to be 13dB or better
• You need to have a detailed analysis, SNR, dispersion, power, nonlinearity etc.
• You should have clear indication of how traffic split to multiple paths
• Every detail of components, in particular losses, should be included.
• Your grade depends on your detail and accuracy
• You have to find all components from existing products. You have to list all
products with component name and key parameters, such as insertion loss, in
your report.
Limitations
• Transmitter power can NOT exceed 3 dBm (2mW) per channel at the
starting power
• Power at the detector should be within the manufacturer specs, no
detector burning high powers, no hypothetical results with extreme low
powers
• Amplifier gain can’t exceed 20dB,
• Power per channel after an amplifier can’t exceed 5mW (7dBm)
• Always think about cost, no generous distribution of components
