Subject Overview:

This subject covers the basic components and technologies used in the physical layer of optical communications systems. In particular, it includes the following topics:

• Time Division Multiplexing (TDM) and Wavelength Division Multiplexing (WDM).
• Digital modulation of light.
• Laser diode operation and modulation.
• Direct and external modulation of light.
• Propagation of light in optical fibres.
• Non-linear effects in optical fibres
• Optical amplification and noise.
• Optical signal detectors.
• Noise in optical communication systems.
• Principles of TDM & WDM networks.
• Optical link design principles.

On completion of this subject, the students will develop skills and knowledge required to understand the fundamentals of Optical Communications:

• The principles and operation of optical communications systems.
• The design of a linear optical communications link.
• The principles of optical signal generation, modulation, propagation and detection.
• Types of network elements in TDM and WDM networks.
• Impact of optical fibre propagation and non-linearities on optical signals.
• Principles of optical amplification.
• The cause and impact of noise in optical communications systems.

The students should be able to understand operation and performance of an optical communication system and provide a simple design of a linear optical link.
Furthermore, they should be able to understand the operation of devices such as laser diodes, optical modulators, optical fibres, amplifiers and receivers.

Assessment: • Formally supervised written examination - 3 hours 60% (end of semester). This final exam is a hurdle. A student must pass the exam to pass the subject. • Written class weekly assignments – 40%;
