Abstract
A system for canceling crosstalk between one or more local distribution point units (DPUs)/fiber extender (FE) and a central distribution point (CDP) in a central office (CO)/cloud. The system can include a processor with memory configured to virtualize signal processing tasks from the DPU/FE, and to the CDP. The virtualization can include moving or splitting signal processing tasks such as a cross talk cancellation operation, from the DPUs/FEs and to the CDP, as virtualization of the tasks, and performing crosstalk cancelation for lines therebetween or with CPEs of a same vectored group.
Claims23
A system for providing network access among a plurality of customer premises equipments (CPEs), the system comprising:
- a first CPE of the plurality of CPEs comprising one or more first ports coupled to a first set of lines in a vectored group;
- a second CPE of the plurality of CPEs comprising one or more second ports coupled to a second set of lines in the vectored group;
- a plurality of distribution point units (DPUs)/Fiber Extenders (FEs) comprising mutual crosstalk with respect to one another as part of the vectored group, wherein the plurality of DPUs/FEs is coupled to a central distribution point (CDP) at a central office (CO) or a cloud network via a fiber link, and the plurality of DPUs/FEs is further coupled to the first CPE via the first set of lines and the second CPE via the second set of lines in the vectored group;
- wherein the CDP, via one or more processors, is configured to perform a timing synchronization and timing alignment between the plurality of DPUs/FEs to reduce/cancel the mutual crosstalk within the vectored group.
A method for a communication system of a customer premise, comprising:
- virtualizing, via one or more processors, one or more signal processing tasks between a plurality of distribution point units (DPUs)/fiber extender (FEs) and a central distribution point (CDP) of a central office (CO)/network cloud component;
- and
- performing, via the one or more processors, a timing synchronization between the plurality of DPUs/FEs and a central point of the CO/network cloud component.
An apparatus of a central distribution point (CDP) of a central office (CO) or a network cloud component for communication with a plurality of digital processing units (DPUs)/fiber extenders (FEs) and customer premise equipments (CPEs), comprising:
- optical analog front ends coupled to copper analog front ends of the plurality of DPUs/FEs, and to the CPEs via lines of a same vectored group that generate mutual crosstalk therebetween, wherein the plurality of DPUs/FEs are non-colocated with respect to one another;
- and
- one or more processors configured to virtualize one or more signal processing tasks from the plurality of DPUs/FEs by moving the one or more signal processing tasks from the plurality of DPUs/FEs and performing the one or more signal processing tasks, and perform a timing synchronization between the plurality of DPUs/FEs to reduce the mutual crosstalk within the same vectored group.
