We supply used and surplus networking hardware — chassis, line cards, route processors, optics and spares — to operators, service providers and equipment resellers worldwide.
BM Global is the trading name of Changsha Ganzao Technology Co., Ltd., a China-based supplier of used and surplus network and telecom equipment.
