Abstract: Disclosed are tubeless fiber optic cables having strength members, methods of making the cables, and methods for making strength members. Specifically, the concepts of the invention inhibit the distortion and/or influence the cross-sectional shape of the tubeless fiber optic cables due to torsional forces from the strength members. For instance, one tubeless fiber optic cable of the invention uses strength members with a dead-lay construction for inhibiting distortion of the same. Another tubeless fiber optic cable design uses strength members on opposite sides of the cavity where the torsional forces from the strength members are in opposite directions for influencing the cross-sectional shape of the same. Other aspects of the invention are directed to methods for making the tubeless fiber optic cables.

Abstract: Systems and methods for are provided tracking electronic files in computer networks using electronic signatures. A signature program installed on a network node inserts an electronic signature into certain encoded media files when they are transferred to other network users. Each network user is issued a unique electronic signature based on public key infrastructure. A signature repository supplies the recipient signature to the signature program prior to transferring a file. The sender and recipient signatures are appended to a portion of the media file, preferably the lower order bits to minimize perceptible file degradation. A transaction record is thereby written into the file and a copy of the transfer information is stored centrally at the repository, thereby creating a traceable record of a file's movement.

In one embodiment, the carrier jacket has a preferential tear portion adjacent to the at least one optical fiber with a substantially continuous outer surface in the carrier jacket adjacent to the preferential tear portion. The preferential tear portion may be defined by at least one of: at least one internal void, at least one weld line, and at least one wing extending from a tape disposed about the one or more optical fibers. Various alternatives are possible. For example, the carrier jacket may also or alternatively include at least one gripping area extending for enhancing the gripping of the carrier section when pulling apart the carrier section and messenger section.

Abstract: A compact optical splitter module is disclosed. One type of compact optical splitter module is a planar attenuated splitter module that includes a branching waveguide network having j?1 50:50 splitters that form up to n?2j output waveguides having associated n output ports, wherein only m<n output ports are suitable for transmitting light to the at least one external output device. This provides a 1×m splitter module wherein each output port has the attenuation of a 1×n splitter module, thereby obviating the need for external attenuation. Another type of compact optical splitter module is a direct-connect splitter module that eliminates the need for an optical fiber array when coupling to external optical fibers. Another type of compact optical splitter module is a microsplitter module that serves as device and module at the same time and that eliminates the differentiation between device and module. The integration of device and module also makes manufacturing the microsplitter module cost-effect.
