Abstract
Various example embodiments for supporting optical communications in an optical communication system are presented herein. Various example embodiments for supporting optical communications in an optical communication system may be configured to support optical communications within a passive optical network (PON) including an optical line terminal (OLT) and an optical network unit (ONU) where communications between the OLT and the ONU is supported based on support for multiple ONU instances of the ONU within the PON.
Claims20
An apparatus, comprising:
- at least one processor;
- and
- at least one memory including instructions which, when executed by the at least one processor, cause the apparatus at least to:
- support, by an optical network unit (ONU) within a passive optical network, a set of ONU instances of the ONU including at least a first ONU instance of the ONU and a second ONU instance of the ONU, wherein the ONU instances in the set of ONU instances are active concurrently at the ONU, wherein the first ONU instance of the ONU has assigned thereto a first allocation identifier and supports a first set of upstream communication settings, wherein the second ONU instance of the ONU has assigned thereto a second allocation identifier different than the first allocation identifier and supports a second set of upstream communication settings different than the first set of upstream communication settings, wherein the first set of upstream communication settings includes a first upstream line rate and the second set of upstream communication settings includes a second upstream line rate different than the first upstream line rate;
- and
- support, by the ONU, upstream communications from the ONU to an optical line terminal (OLT) according to different upstream communication settings by switching between ONU instances within the set of ONU instances of the ONU for upstream communications from the ONU to the OLT.

A method, comprising:
- supporting, by an optical network unit (ONU) within a passive optical network, a set of ONU instances of the ONU including at least a first ONU instance of the ONU and a second ONU instance of the ONU, wherein the ONU instances in the set of ONU instances are active concurrently at the ONU, wherein the first ONU instance of the ONU has assigned thereto a first allocation identifier and supports a first set of upstream communication settings, wherein the second ONU instance of the ONU has assigned thereto a second allocation identifier different than the first allocation identifier and supports a second set of upstream communication settings different than the first set of upstream communication settings, wherein the first set of upstream communication settings includes a first upstream line rate and the second set of upstream communication settings includes a second upstream line rate different than the first upstream line rate;
- and
- supporting, by the ONU, upstream communications from the ONU to an optical line terminal (OLT) according to different upstream communication settings by switching between ONU instances within the set of ONU instances of the ONU for upstream communications from the ONU to the OLT.
An apparatus, comprising:
- at least one processor;
- and
- at least one memory including instructions which, when executed by the at least one processor, cause the apparatus at least to:
- support, by an optical line terminal (OLT) for an optical network unit (ONU) within a passive optical network, a set of ONU instances of the ONU including at least a first ONU instance of the ONU and a second ONU instance of the ONU, wherein the ONU instances in the set of ONU instances are active concurrently for the ONU, wherein the first ONU instance of the ONU has assigned thereto a first allocation identifier and supports a first set of upstream communication settings, wherein the second ONU instance of the ONU has assigned thereto a second allocation identifier different than the first allocation identifier and supports a second set of upstream communication settings different than the first set of upstream communication settings, wherein the first set of upstream communication settings includes a first upstream line rate and the second set of upstream communication settings includes a second upstream line rate different than the first upstream line rate;
- and
- support, by the OLT, upstream communications from the ONU to the OLT according to different upstream communication settings by switching between ONU instances within the set of ONU instances of the ONU for upstream communications from the ONU to the OLT.
