  • Patent number: 10972209
    Abstract: The present invention includes novel techniques, apparatus, and systems for optical WDM communications. Tunable lasers are employed to generate respective subcarrier frequencies which represent subchannels of an ITU channel to which client signals can be mapped. In one embodiment, subchannels are polarization interleaved to reduce crosstalk. In another embodiment, polarization multiplexing is used to increase the spectral density. Client circuits can be divided and combined with one another before being mapped, independent of one another, to individual subchannels within and across ITU channels. A crosspoint switch can be used to control the client to subchannel mapping, thereby enabling subchannel protection switching and hitless wavelength switching.

  • Patent number: 10882553
    Abstract: A kingpin assembly includes a pin that has a shaft with a spherical member extending therefrom. The kingpin includes a base that has a spherical interior surface which defines an interior area. The interior area includes an open end of the base and is bounded by a closed end of the base. The closed end of the base is opposite the open end. The spherical member is rotatingly disposed in the interior area with the shaft extending away from the open end. The closed end has a torque receiving configuration for receiving a torque applying tool thereon.

  • Patent number: 10655733
    Abstract: An impact resistant seal includes an annular body extending between a first end and a second end. The annular body includes a first anchor formed on the first end and a second anchor formed on the second end. The impact resistant seal includes an elastomeric section having an exterior surface which extends between the first anchor and the second anchor. The elastomeric section is expandable and contractible in response to movement of the first anchor relative to the second anchor. The impact resistant seal includes a plurality of protrusions extending radially outward from the exterior surface and extending circumferentially around the elastomeric section. Adjacent ones of the plurality of protrusions are spaced apart from one another by a predetermined spacing magnitude configured to accommodate the movement of the first anchor relative to the second anchor.

  • Patent number: 10630418
    Abstract: The present invention includes novel techniques, apparatus, and systems for optical WDM communications. Tunable lasers are employed to generate subcarrier frequencies representing subchannels of an ITU channel to which client signals can be mapped. Client circuits can be divided and combined before being mapped, independent of one another, to individual subchannels within and across ITU channels. Subchannels may be independently routed to a single subchannel receiver filter, such that each subchannel detected at the receiver may come from a different source location. Network architectures and subchannel transponders, muxponders and crossponders are disclosed, and techniques are employed (at the subchannel level/layer), to facilitate the desired optical routing, switching, concatenation and protection of client circuits mapped to these subchannels across the nodes of a WDM network. Subchannel hopping may also be used to increase the optical network security.

  • Publication number: 20200072277
    Abstract: A ball joint includes an outer race having an exterior surface extending from an outer axial end to an inner axial end thereof and having an interior that has an opening proximate the outer axial end. The ball joint includes a ball with a stem extending therefrom. The ball is disposed in the interior area with the stem extending out of the opening. The ball joint has an anti pull-out collar disposed around the outer race and located entirely beyond a center point of the ball towards the outer axial end of the outer race. The anti pull-out collar has a radial thickness configured to prevent radial expansion of the outer race.

  • Publication number: 20170230133
    Abstract: This invention relates to provisioning wavelength-selective switches and reconfigurable optical add-drop multiplexers to minimize the bandwidth narrowing effect from the optical filters. Novel architectures and methods are disclosed that can significantly reduce bandwidth-narrowing on channels in a reconfigurable WDM network where a large number of optical filter elements are cascaded. Instead of blocking unused channels as in the prior art, unused channels are selectively provisioned depending on the state of their adjacent channels. Unused adjacent channels of an active channel are provisioned to follow the same path as the active channels. As each channels is deployed, the channel frequency is selected so as to minimize bandwidth narrowing.
