Abstract

A system and method for providing a hybrid fiber network (HFN) means to identify a fiber node by a unique address. An addressing module is installed in proximity to, or collocated with, a fiber node. The addressing module comprises an addressing module identifier that associates the addressing module with a particular fiber node. Network parameter values are received from the fiber node by the addressing module and reported to a reporting station.

a first interface for connecting the addressing module to the fiber node on its subscriber side;

a second interface for connecting the addressing module to one or more test points of the fiber node; and

a logic module internal to the addressing module adapted to;

receive an addressing module identifier from the HFN, wherein the addressing module identifier associates the addressing module with the fiber node;

receive from the one or more test points one or more network parameter values related to the performance of the HFN; and

send the one or more network parameter values to a reporting station in association with the addressing module identifier.
