Abstract
Disclosed are systems and methods which provide communications to a subscriber level of a network using a hybrid communication network. Preferred embodiments of a hybrid communication network of the present invention provide communications using both fiber media and electrically conductive media. Preferred embodiments of the present invention bring fiber optic cables to a point just beyond the last transformer before a subscriber in the power grid. At a point on the subscriber side of the last transformer, e.g., a low voltage subscriber distribution point transformer, the communication signal is preferably coupled from the fiber optic cable of the preferred embodiment to the power transmission line.
