Amplifier Strategies for Multiband Optical Transmission Systems
Optical communication systems are the backbone of current communication network as they allow fast and reliable information exchange. However, the advent of new generation applications and services require an ever increasing demand for higher capacity, lower cost, and lower energy consumption. According to discussions in , because of the difference in the growth rates between the fiber capacity and the traffic demand, there is expected to be a capacity shortage within the next decade.
Among several options for increasing the capacity of installed optical fibers, exploiting new wavelength bands appears to be a promising and economical solution. Extending the transmission bandwidth from conventional band (C-band) to multi-band (MB), researchers are aiming to transmit information over the entire single mode fiber spectrum. This will increase the optical capacity and thus postpone the need to deploy new fibers.
The challenges for the realization of such multiband networks lie both in the development of key components – as well as in the modelling of the physical and network.
Throughout this seminar, using the work of , optical amplification techniques for different optical bands will be investigated. Studying the characteristic properties of optical amplifiers for distinct optical bands, the task of the student is to write a report and give a presentation on the key points discussed in the paper.
