Course detail

Optical Networks

FEKT-MPA-OSEAcad. year: 2026/2027

The course focuses on optical fibers, optical cables, and optical communication systems. Students will become familiar with the principles of light propagation in optical fibers, the basic types of single-mode, multimode, and polymer optical fibers (POF), their transmission properties, manufacturing technologies, and optical cable construction. Attention is also paid to optical fiber splicing, optical connectors, and basic passive and active optical components, including optical splitters, circulators, isolators, attenuators, optical sources and detectors, amplifiers, modulators, and switches.

The course also covers the physical aspects of optical fiber transmission, particularly attenuation, chromatic dispersion, polarization mode dispersion, linear and nonlinear effects, and methods for their mitigation or compensation. The principles of wavelength-division multiplexing (WDM, CWDM, and DWDM), high-speed optical transmission, modern modulation formats, polarization multiplexing, and coherent transmission systems are discussed. Furthermore, the course addresses FTTx optical access network architectures and passive optical networks (PON), optical transport and backbone networks, and the basic principles of their design and operation. The final part focuses on measurement, diagnostics, and monitoring of optical telecommunication networks, particularly transmission and optical time-domain reflectometry (OTDR) methods, as well as the basic principles of fiber-optic sensors, including fiber Bragg gratings, interferometric sensors, and distributed fiber-optic sensing systems.

Entry knowledge

Profficiency is required on the Bachelor's degree level. Students should have the knowledge of signal transmission. Some basic knowledge in the area of transmission of binary signals and be able to tackle distortions in the transmission. It is recommended for the completion of the course Transmission media, taught in the second year of the bachelor program.

Rules for evaluation and completion of the course

The requirements for successful completion of the course are specified annually in the current regulations issued by the course coordinator.

A maximum of 40 points can be obtained for laboratory work, consisting of:

  • 10 points for laboratory exercises,
  • 10 points for the laboratory test,
  • 20 points for the invidual project.

A maximum of 60 points can be obtained for the written examination.

Attendance at laboratory classes is compulsory. Any missed laboratory class must be made up by prior arrangement with the instructor. Students are required to properly excuse their absence in advance and, in the case of absence due to illness, provide a medical certificate.

 

 

Aims

The aim of the course is to provide students with knowledge of the principles, technologies, and technical solutions used in optical communication systems and networks. The course provides a comprehensive overview ranging from optical fiber and cable properties, fiber splicing, and optical components to high-speed transmission technologies, access and transport optical networks, multiplexing, measurement, diagnostics, and monitoring of optical links.

After completing the course, students will be able to:

  • describe the principle of light propagation in optical fibers and compare the properties of single-mode, multimode, polymer, and selected specialty optical fibers,
  • assess the suitability of different types of optical fibers and cables for various communication applications,
  • understand the construction, manufacturing, installation, and joining methods of optical fibers and cables and practically perform basic fiber preparation and fusion splicing,
  • explain the operating principles and key parameters of passive and active optical components, optical sources, detectors, amplifiers, modulators, and switches,
  • describe the impact of attenuation, chromatic dispersion, polarization mode dispersion, and nonlinear effects on optical fiber transmission and explain basic methods for their mitigation or compensation,
  • explain the principles of high-speed optical transmission, including modern modulation formats, polarization multiplexing, coherent transmission, and optical transceivers,
  • explain the principles of wavelength-division multiplexing (WDM, CWDM, and DWDM) and their use in optical communication systems,
  • understand the architectures of FTTx optical access networks and passive optical networks (PON), including their standards, generations, and transmission rates,
  • describe the principles of local, metropolitan, access, transport, and backbone optical networks and select appropriate technologies for specific types of optical infrastructure,
  • perform basic measurements of optical fibers and links using transmission and optical time-domain reflectometry (OTDR) methods, evaluate measured parameters, and identify typical events and faults,
  • understand the principles of monitoring and supervision of optical networks,
  • describe the basic principles of fiber-optic sensors, particularly fiber Bragg grating sensors, interferometric sensors, and distributed fiber-optic sensing systems.
