query: What is a passive optical network (PON)?
answer: A passive optical network (PON) is a fiber-optic telecommunications technology that delivers broadband network access to end-customers using a point-to-multipoint topology.  A single optical fiber serves multiple endpoints via unpowered fiber optic splitters, often considered the 'last mile' between an internet service provider (ISP) and its customers.
