It is a fiber-optic telecommunications technology for delivering broadbandnetwork access to end customers. Its architecture implements a point-to-multipoint topology in which asingle optical fiber serves multiple endpoints by using unpowered(passive)fiber optic splitters to dividethe fiber bandwidth among the endpoints. Passive optical networks are often referred to as the last milebetween an Internet service provider (ISP)and its customers.
