Abstract

In this paper, we have investigated the use of fast wavelength switching optical transmitters and a wavelength selective space switching all-optical network for cellular fronthaul applications. System capacity is calculated by using hard-deadlines that arise from the radio requirements and the physical constraints of the optical network. The results show that the approach proposed can reduce hardware costs by 50% while satisfying the stringent latency requirements of evolving 5G fronthaul systems. An analysis of the impact of varying the switching times of the transmitter and the reconfiguration time of the space switch reveals the limits (1us and 1ms respectively) where the system offers potential benefits compared to fixed networks.
