4. Describe the operating principle behind an Erbium Doped Fiber
Amplifier (EDFA).
5. You are required to design an optical communications system
between two locations 300 km apart. The power transmitted is 0 dBm
and the receiver sensitivity is -29 dBm. The attenuation
coefficient for the cable is 0.24 dB/km and there is a splice every
4 km, with a loss of 0.1 dB per splice.
If the connector loss is 0.2 dB explain how you would incorporate
an optical amplifiers into your design to ensure the correct
operation of this system.
6. Describe the different types of dispersion in an optical
fiber.

Photonics and Optical Revision Sheet 1 1. Caculate the photon energy in eV for a wavelength of 1.55 um 2, A 1.55 μm digital communications system operating at 4 GBits/s receives an average power of -24 dBm at the detector. On the assumption that 1 and 0 bits are equally likely to occur how many photons are received within each 1 bit? 3. A1.3 um digital communications system operating at 3 GBits/s receives an average power of -29 dBm at...
1. You have 25 km of optical cable with an attenuation coefficient of 0.27 dB/km. What is the total attenuation due to the cable? 3. Considering further question 1. If the power transmitted is 1 mW and the receiver sensitivity is -30 dBm what is the maximum distance of optical fiber that can be used before amplification is needed? You can assume only cable losses. 4. Considering further Question 3. What is the effect of adding connectors of loss 0.23...
Designing a High speed Wireless Data Link Line of Sight Link Budget Analysis Several major factors that can impact the performance of a radio system are Available/permitted output power e Bandwidth, . Receiver sensitivity Antenna gains In this case study, the students will be required to calculate the link budget for a LOS Wireless link. Read through the following to understand some of the aspects and elements that need to be considered when calculating a Link Budget. If the estimated/calculated...
