By Nitin Dahad – A manufacturer of III-V photonic devices claims to have proven the feasibility of 60-GHz radio over fiber (ROF) transmission at a 1,270-nm wavelength, paving the way to potential solutions for 5G networks.
CST Global, a Scotland-based subsidiary of Sivers IMA Holdings AB in Kista, Sweden, carried out the feasibility study as part of an EU Horizon 2020 research project. The project, iBROW (innovative ultra-broadband ubiquitous wireless communications through tera-hertz transceivers), was led by the University of Glasgow and managed within CST Global by research engineer Horacio Cantu.
The company says that ROF networks are emerging as a completely new and promising communication paradigm for delivering broadband wireless access services and fronthaul at 60 GHz, relying on the synergy between fixed optical and millimeter-wave technologies. ROF technology enables RF signals to be transported over fiber across kilometers and can be engineered for unity gain RF links. Hence, it is thought that it could do a lot to ease spectrum constraints, and it can replace multiple coax cables with a single fiber-optic cable. Among several benefits, ROF could also enhance cell coverage. more>
