Magistrate Judge Burke recommends construction of claim terms relating to optical networking.

Magistrate Judge Burke recently issued a report and recommendation construing claims of U.S. Patent No. 6,973,229, titled “Node Architecture for Modularized and Reconfigurable Optical Networks, and Methods and Apparatus Therefor.” Lambda Optical Solutions, LLC v. Alcatel-Lucent USA Inc., C.A. No. 10-487-RGA-CJB (D. Del. Aug. 3, 2012). Judge Burke recommended constructions of the following terms:

“optical access ingress subsystem”
“optical access ingress subsystem which is adapted to receive an optical signal associated with an access network”
“optical access egress subsystem”
“optical access egress subsystem which is adapted to direct the optical signal toward an access network”
“transport ingress subsystem”
“transport egress subsystem”
“adapted to selectively provide optical coupling between the transport ingress subsystem and at least one of (1) the optical access egress subsystem, and (2) the transport egress subsystem”
“adapted to selectively provide optical coupling between the transport egress subsystem and at least one of (1) the optical access ingress subsystem and (2) the transport ingress subsystem”
“specified optical input”
“specified optical output”
In addition, Judge Burke recommended the parties’ agreed-upon construction of the following terms:

“access network”
“all-optical switch”
