Methods and apparatus are described for forward baseband digitalization. A method includes receiving a forward baseband digital optical signal from an optical fiber; transforming the forward baseband digital optical signal to a forward analog electrical signal; transmitting the forward analog electrical signal on an electrical conductor; receiving a reverse analog electrical signal on the electrical conductor; transforming the reverse analog electrical signal to a reverse digital baseband optical signal; and transmitting the reverse digital baseband optical signal. An apparatus includes a forward baseband digital optical signal receiver; a forward circuit coupled to the forward baseband digital optical signal receiver, the forward circuit transforming a forward baseband digital optical signal to a forward analog electrical signal; a forward analog electrical signal transmitter coupled to the forward circuit; a reverse analog electrical signal receiver; a reverse circuit coupled to the reverse analog electrical signal receiver, the reverse circuit transforming a reverse analog electrical signal to a reverse digital baseband optical signal; and a reverse baseband digital transmitter coupled to the reverse circuit.

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. The systems and methods provide advantages because the need for muxnode units is eliminated, the cost of the node units is reduced, the amount of optical fiber is reduced and the reverse bandwidth is increased.

Reverse digitized communications architecture

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.

Systems and methods are described for communications networks. A method, includes deploying a communication link, at least a portion of which is protected against active equipment failure, that includes a splitter-combiner communicatively coupled between a data drop/add device and a headend. The systems and methods provide advantages because a communication network can be protected, at least in-part, against active equipment (e.g., data drop/add device) failure, passive equipment (e.g., optical fiber) failure, and/or equipped for non-intrusive expansion of the network.

Active equipment protection methods and apparatus

Systems and methods are described for wireless communications. A method includes providing a wireless communications system having narrow cast bi-directional internet channel capability and defining a substantially nonconflicting regional overlay, then transmitting a downstream signal from a downstream transmitter to a bi-directional transceiver; and transmitting an upstream signal from the bi-directional transceiver to an upstream receiver through the substantially nonconflicting regional overlay. The narrow cast bi-directional internet channel capability and the non-conflicting regional overlay define an upstream area that overlies a plurality of smaller downstream areas. The systems and methods provide advantages because additional capacity can be provided within a saturated region without incurring interference and additional capacity can be provided only in the direction in which it is needed.
