The Beer & Broadband roundtable series is a virtual discussion series bringing together leaders in the broadband and infrastructure space to share their thoughts without egos, agendas or selling.
This clip is from a larger discussion surrounding “Private and Public Partnerships”. Watch the full hour here: [ Ссылка ]
In this clip we discuss three approaches: Dark Fiber, Lit Fiber and Conduits:
Dark Fiber Approach: The infrastructure provider is responsible for the physical fiber
plant. This includes constructing the network, responding to and repairing fiber breaks, splicing new fiber, and performing ongoing maintenance tasks. Building and maintaining a dark fiber network also requires access to poles and/or conduit. The service provider lights the fiber and provides services and customer-premises equipment. When a new subscriber takes service, the infrastructure provider typically also is responsible for constructing the fiber “drop” cable from the street to the subscriber’s home, where it connects to a network interface device at the premises.
Lit Fiber Approach: The infrastructure provider is responsible for the fiber network as well as for providing the network electronics required to light the fiber and deliver services from the service provider to the subscriber (terminating at an optical networking terminal located inside or on an outside wall of the customer premises). The lit fiber provider also creates a network operations center and performs ongoing maintenance and support tasks. The service provider sells services to subscribers using a virtual circuit over this lit network.
Conduit Approach: The public infrastructure provider is responsible for the physical conduit plant. This typically includes constructing the conduit network, responding to and repairing any conduit breaks, maintaining network documentation, and providing access points for the service provider. The service provider does the rest, pulling fiber through the conduit, lighting the fiber and providing services.
