  • Patent number: 12057689
    Abstract: A hybrid cable distribution system wherein a feeder cable is received by a box. The feeder cable can be a hybrid cable including optical fibers and copper wire (coax). The box may be used only for copper signal handling (such as coaxial signal handling), and then at a later date, the box may be used for receiving fiber signals. Customers can directly connect to the feeder fan out device by connecting a tail of a drop splice module that is spliced to an individual distribution cable to the feeder fan out device. This connection creates a point-to-point connection. The number of fan out devices in the system can be increased or decreased as needed. Alternatively, a splitter input can be connected to the feeder fan out device, such as through a pigtail extending from the splitter, wherein the splitter splits the signal as desired into a plurality of outputs. The outputs of the splitters can be in the form of connectors or adapters.

  • Patent number: 11489319
    Abstract: A workstation and method for the installation of a pulling head assembly onto one or more conductors of a cabling system are provided. The workstation incorporates one or more of: a conductor clamp that holds the conductors of the cabling system in place during the installation of the pulling head assembly; a cutting guide having indicia marks that indicate the lengths to which to cut the conductors in order to achieve a staggered pattern of pulling eyes attached to the conductors in the pulling head assembly; a stripping tool that is used to remove a portion of the insulation from the terminal end of each conductor so that the end of the conductor may be inserted into the pulling eye; and a crimping tool that is used to crimp the pulling eyes onto the terminal ends of each of the conductors.

  • Patent number: 11435540
    Abstract: A cable management system includes a cap that cooperates with a housing to enclose a connection between a first cable and a second cable. The cap defines a first port and a second port through which cables extend into the housing. A base is to be coupled to the cap. The base includes a first clamp that protrudes from a surface of the base and maintains an alignment of a portion of the first cable with the first port. The base also includes a base interlock portion. A first cable guide, separate from the base, is to be installed on the cap to maintain an alignment of a portion of the second cable. The first cable guide includes a second clamp, and a first cable guide interlock portion that cooperates with the base interlock portion to interfere with separation of the first cable guide from the base.

  • Patent number: 11309965
    Abstract: An optical filter comprises an array of waveguides fabricated on an optical integrated circuit (PIC). The array comprises individual waveguides, each of which receive light inputs, e.g., individual taps of a multi-tap optical filter used in an interference cancellation circuit. Typically, the output(s) of the individual waveguides are located at an exit (edge) of the PIC. At least one second waveguide in the array is patterned on the PIC in a converged configuration such that the light transiting these waveguides co-propagates and interacts across given portions of the respective waveguides before exiting the waveguide array along a common facet, thereby generating or inhibiting one of intermodulation products, and harmonics. This structural configuration enables the generation of various modes of transmission at the PIC exit, enabling more efficient transfer of the energy, e.g., to an associated photodetector (PD) that provides conversion of the energy to the RF domain.

  • Patent number: 11307356
    Abstract: An optical module that has a structure ensuring reduction in size. The optical module has a structure where a part of a fiber block is protruded from a housing. By including a thin plate, this optical module can avoid entering of dust in the housing, allows a position shift of the fiber block due to a mounting position error of an optical component in the housing, a position shift of an opening portion due to a dimensional error of the housing, or a displacement due to a temperature change, and can reduce the coupling loss due to the optical axis misalignment.
