Evolution of fiber in the residential loop plant

The current status of fiber in the subscriber loop in the U S is reviewed. Efforts to promote a standardized approach are briefly examined. Issues involved in powering the distributed optoelectronic curbside terminals, designated optical network units (ONUs), adding video capability when, where, and as needed, and developing strategies for evolving narrowband fiber to the curb (FTTC) to broadband FTTC, including fiber extended to the home if warranted, are discussed. Loop architecture of the future are considered, and business issues are addressed.<>
