Abstract: A communication multiplexer device is provided. The multiplexer device includes a legacy port adapted to communicate a legacy data frame format having at least one major data frame. The legacy major data frame includes overhead fields which may include a sync field. The legacy major data frame also includes three minor frame groups, where each of the minor frame group includes minor frames having subframe formats. The multiplexer also includes a contemporary port adapted to communicate a contemporary data frame format; and a translator coupled between the legacy port and the contemporary port for translation between the legacy data frame format and contemporary data fame format.

Abstract: A fiber optic cable including a cable core having at least one optical fiber and a ripcord. In one embodiment, the ripcord is a conductive material operative, upon application of a sufficient pulling force, to rip at least one cable component for facilitating access to said at least one optical fiber. In other embodiments, the ripcord is formed from a semi-conductive material, the ripcord is removably attached to at least one cable component, and/or the ripcord has an excess length.
