  • Publication number: 20250116833
    Abstract: An optical fiber ribbon may be intermittently bonded with a repeating pattern of bond lengths and gap lengths configured to enhance flexibility and robustness of the optical fiber ribbon. The ribbon may include a plurality of optical fibers where a first adjacent two of the optical fibers may be intermittently connected together by the bond portions arranged in a longitudinal pattern which may have a constant bond length or may have a constant distance between bond portions. A second adjacent two of the optical fibers may be intermittently connected together by the bond portions arranged in the longitudinal pattern where a first bond portion of the second adjacent two of the optical fibers may be offset from the first bond portion of the first adjacent two of the optical fibers in the longitudinal direction by a first offset length (O1).

  • Publication number: 20250093601
    Abstract: Multi-conductor ribbon structures may be structurally configured to reduce cable installation time. Such ribbon structures may include an adjacent conductor portion and a bonding portion that may be structurally configured to surround at least a conductor portion of the adjacent conductor portion. The adjacent conductor portion may be partially or wholly surrounded by a coating portion having an outer surface portion. The bonding portion may form a separation portion between the outer surface of each of the adjacent conductors. The separation portion may include a reduced amount of the bonding material adjacent to a first portion of the adjacent conductor portion relative to an amount of the bonding material portion adjacent a second portion of the adjacent conductor portion so as to provide a preferential separation region between the adjacent conductor portion at the first portion of the adjacent conductor portion.

  • Patent number: 11955254
    Abstract: The present disclosure describes methods of manufacture and implementations of hybrid separators for data cables having conductive and non-conductive or metallic and non-metallic portions, and data cables including such hybrid separators. A hybrid separator comprising one or more conductive portions and one or more non-conductive portions may be positioned within a data cable between adjacent pairs of twisted insulated and shielded or unshielded conductors so as to provide physical and electrical separation of the conductors. The position and extent (laterally and longitudinally) of each conductive portion and each non-conductive portion may be selected for optimum performance of the data cable, including attenuation or rejection of cross talk, reduction of return loss, increase of stability, and control of impedance.

  • Patent number: 11888865
    Abstract: Systems and methods of the disclosure can implement intrusion radiation protection (IRP) to prevent malicious IP traffic in a secure network. The IRP system can receive an IP packet, determine that a protocol of the IP packet matches a predetermined policy of a plurality of predetermined policies, classify the IP packet based on the predetermined policy and a size of the IP packet, inspect a payload of the IP packet responsive to the classification to determine features of the IP packet, determine that one of the features of the IP packet is improper based on the classification, and flag the IP packet as suspect based on the determination. The IRP system can log and/or drop the flagged IP packet. The IRP system can additionally replace a payload of the IP packet with a second payload, and transmit the IP packet with the second payload to its destination.

  • Patent number: 11522800
    Abstract: The present disclosure is directed generally to systems and methods for dynamically selecting a retransmission rate for communication between two devices. The retransmission rate may be selected after a transmission has failed between the devices. In some embodiments, the retransmission rate may be selected based on relative velocity of the devices. In some embodiments, the retransmission rate may be selected based on transmission channel characteristics. The retransmission rate may be selected such that the retransmission will be less than an allowable transmission rate based on a distance between the two devices.

  • Patent number: 11459205
    Abstract: The present disclosure describes methods of manufacture and implementations of cable storage and dispensing systems combining the advantages of reel-based systems and box-based systems. The present system may be manufactured entirely out of corrugated cardboard or similar materials, reducing expense and weight compared to systems with wood, plastic, or metal reels or flanges, and adding recyclability in a single paper-based waste stream. The system may dispense cable in the same manner as reel-based systems, reducing tangling and aiding installation and deployment compared to box-based systems that do not utilize reels or spools. The system does not require the use of reel stands or other external components, and may be light and portable.

  • Patent number: 10832833
    Abstract: Two electromagnetic interference (EMI) controlling tape application methodologies for unshielded twisted pair (UTP) cable include Fixed Tape Control (FTC) and Oscillating Tape Control (OTC). In FTC, tape application angle and edge placement are controlled to maintain position of the tape edges over a base of nonconductive filler in the cable. In OTC, the tape application angle is continuously varied, resulting in crossing of the tape edges over all of the pairs of conductors with varying periodicity. In both implementations, the filler allows a cylindrical shape.
