Patent number: 11342994Abstract: A multimode combiner or coupler (MMC) may combine the inputs into a larger core multimode fiber. The multimode combiner may be combined with a re-transmitting laser for detecting and re-transmitting signals. Thus, the multi-mode combiner may detect and combine input signals, and then retransmit the detected, combined signal. The detection can be implemented with multiple single mode fibers to small single mode detectors or a multi-mode coupler with a larger multi-mode detectors. In embodiments of the MMC, a bi-directional optical splitter/combiner includes a transmitter for re-transmitting an RF signal received at a receiver, a first wave division multiplexer (WDM) combiner combining the output of the first transmitter in an upstream direction to a downstream signal in a downstream direction, and a second WDM combiner combining split downstream signals in the downstream direction with upstream signals received via at least two optical fiber inputs.Type: GrantFiled: April 6, 2021Date of Patent: May 24, 2022Assignee: ARRIS Enterprises LLCInventors: Venkatesh G.

Patent number: 9917648Abstract: Particular embodiments provide a method for delivering data in the upstream direction without the need for upstream radio frequency (RF) modulation. For example, in some embodiments, an optical network may reach to a gateway associated with a user device. The gateway may receive digital baseband data from the user device in the upstream direction. The gateway can then send the digital baseband data through the optical network without modulating the digital baseband signal via radio frequency. At the headend, because no modulation is performed in the upstream direction, there is no need for de-modulation in the headend. In one embodiment, a scheduler-based approach is used to avoid instances of optical beat interference in the upstream direction as only one upstream device that may interfere with other devices may be able to send data at one time.Type: GrantFiled: October 1, 2014Date of Patent: March 13, 2018Assignee: ARRIS Enterprises LLCInventors: Zoran Maricevic, Dean Stoneback, Marcel F. Schemmann, Amarildo Vieira, Venkatesh G. Mutalik

Patent number: 9742495Abstract: Disclosed are techniques for timing correction for a DOCSIS Edge-QAM. Unlike the DTI required at the headend in existing solutions for DOCSIS Edge-QAM timing, the disclosed techniques may use an Edge-QAM timing deeper in to the network. The N-QAM, referring to an Edge-QAM that is deeper in the network, may be in the optical node configured to convert signals from a network headend or hub for delivery to a subscriber network element. The N-QAM device located in the node may include a local clock for deriving a local time for incoming transport streams, modulating the transport streams onto a downstream carrier for delivery to subscriber network elements using the local clock time, and adjusting the local clock time based on an average value of timestamps in the incoming transport streams.Type: GrantFiled: September 4, 2013Date of Patent: August 22, 2017Assignee: ARRIS Enterprises LLCInventors: Dean A.

Patent number: 9031409Abstract: A headend communications device communicates via a network to downstream network elements, such as cable modems coupled behind optical network units, and allocates and grants timeslots for upstream transmissions from the network elements. The headend communications device has a scheduler for managing and controlling timeslot allocations in a manner avoiding interference such as optical beat interference or FM carrier collisions. The scheduler identifies two or more cable modems or like customer network elements served by the headend communications device that will cause at least a pre-determined intolerable level of interference when allocated overlapping timeslots for upstream transmissions and prevents these two or more cable modems or network elements from being allocated and granted overlapping timeslots.Type: GrantFiled: April 29, 2011Date of Patent: May 12, 2015Assignee: ARRIS Technology, Inc.Inventors: Nagesh S.
