“…This means that no interoperability between the optical transceivers is ensured whatsoever, which complicates the engineering rules and possible migration paths in what concerns reach, optical power budgets, wavelengths and even pluggable form factor types used in the optical links. This is the reason why many operators are currently backing up ongoing standards by the IEEE and the ITU on 10, 25 and 50 Gb/s bidirectional PtP (ITU-T G.9806 and IEEE 802.2cp) and expectations are that both standardization organisms can align their PHY layer requirements [23]. Besides interoperability, the standardized interfaces would enable interesting features such as management and monitoring of the optical links.…”

In this invited paper, we discuss how optical fibers, the de-facto choice for last-mile connectivity of radio access network equipment, can rise to the challenges of 5G. We start by addressing technologies and trends for pointto-point connectivity, from fully passive to auto-tunable wavelength division multiplexing. Then, we assess niche solutions based on point-to-multipoint optical connectivity and possible scenarios allowing fixed-mobile convergent topologies. Finally, we briefly exploit the potential of abstraction of optical and radio access equipment through software defined networking for intelligent and multi-tenancy ready traffic management compliant with the constraints of mobile interfaces and hosting locations of cloud infrastructures.
