Transmission speed has always been an important factor in telecom networks carrying voice, data and videox000D
applications. However, with the emergence of new applications such as cloud computing, video and wirelessx000D
Long Term Evolution (LTE) services and storage area network (SAN) applications in the last years, as well asx000D
the requirements for future 5G networks, transmission speed and low latency are now crucial in many activitiesx000D
of companies involved in the Information and Communications Technologies (ICT) sector.x000D
The current problem faced by ICT companies is mainly related to the speed of information propagation inx000D
conventional fiber-optic networks. Latency in fiber-optic networks is generated by the optical fiber itself, thex000D
optical amplifiers and dispersion compensating fibers, as well as the optoelectronic devices. Because of thex000D
actual design of the current optical fibers, the speed of propagation of light waves is much less than thex000D
propagation speed of free space waves, mainly because of the material that constitutes its core. Currentx000D
approaches to address this problem are multifold and include transponders without forward-error-correctionx000D
(FEC), Raman amplifiers, dispersion compensating modules based on Fiber Bragg Gratings (FBG), as well asx000D
advanced switch architectures and packet-optical technologies or even microwave links. However, thesex000D
solutions have limitations and do not fully address the problem. Progress has been made in the last few years inx000D
the development of new fiber waveguides with much lower core refractive indices ?refs?. The applicability ofx000D
these new fiber structures in real network deployment conditions has not yet been demonstrated.x000D
The proposed project will explore low latency fiber technologies. Microstructured optical fibers based onx000D
innovative waveguide designs do offer some unique optical properties that are impossible to attain with currentx000D
conventional singlemode optical fibers. The project will consist in evaluating different microstructured fiberx000D
technologies, with the objective to determine the most promising approaches for realizing low latency opticalx000D
links.
