Increasing network centralization and the proliferation of radio x-haul over fiber will lead to the effective convergence of optical networks - previously considered to be distinct. This work proposes system-level design considerations and requirerments for network convergence and wired/wireless service co-existence in future optical access.
We review the role of optical fiber as a transport medium in the three generations of in-building wireless networks. We show that fiber becomes a necessity for 5G radio access networks (RAN) operating in high-bandwidth regions of the spectrum at millimeter wave (mmWave) frequencies.
This paper proposes a novel cancellation technique of a Fresnel reflected light in single-wavelength bidirectional wavelength division multiplexed passive optical network (WDM-PON) transmission system. We experimentally confirmed error vector magnitude (EVM) and bit error rate (BER) improvements in comparison with no cancellation case.
This paper proposes a novel delay aware dynamic bandwidth allocation scheme to maximize the number of transmittable ONUs within latency requirement for fronthaul. We confirm that the total number of the transmittable ONUs is 23.5% improved.
