Chinese vendor Huawei has announced that it has been selected by Spanish-backed full service provider Movistar to deploy a commercial optical transport network (OTN)-based 400G wavelength-division multiplexing (WDM) network in Santiago to support the operator’s IPTV and Long Term Evolution (LTE) rollouts, which are expected to place ‘huge bandwidth pressure’ on the telco’s infrastructure. Huawei claims that the system will be the ‘industry’s fastest metropolitan WDM network on 400G OTN technology.’ The project will adopt Huawei’s 100G technology as well as PDM-16QAM-based coherent 400G technology to deliver maximum bandwidth for Movistar’s data centres in the Chilean capital. OTN-based multiplexing, cross-connection, and grooming of multi-granular traffic will also be introduced into the super-fast system to optimise transmission flexibility and efficiency. The vendor also commented that Santiago represents nearly 40% of Chile’s population, 45% of its GDP and has the largest bandwidth consumption of any city in the country.
