Abstract: Systems and methods are described for reverse digitized communications. A method includes: providing at least one optical fiber from at least one member selected from the group consisting of a headend and a hub, a minifibernode coupled to said at least one optical fiber, and an electrical conductor coupled to said minifibernode; transforming a forward optical signal from said at least one optical fiber to a forward analog electrical signal on said electrical conductor at said minifibernode; and transforming a reverse analog electrical signal on said electrical conductor to a reverse digital optical signal at said minifibernode.

Abstract: Systems and methods are described for communications links with non-intrusive expansion capability. A first splitter combiner switches form a shut state to a bypass state when a second headend output is communicatively coupled to a first upstream input and a second headed output is communicatively coupled to a first downstream output. The first splitter combiner is then switchable back to the shut state from the bypass state when the either the second headend output is communicatively decoupled from the first upstream input or the second headend input is communicatively decoupled from the first downstream output. The systems and methods provide advantages because a communication network can be equipped for non-intrusive expansion of the network.
