Abstract:
1. A method of authenticating first and second active optical modules that terminate first and second active optical cable segments, each of which having a respective active end and a respective passive end, the method comprising: reading, by a first device, information from a respective active-end storage device included in the respective active optical module that terminates the first active optical cable segment, wherein the first device is connected to the first active optical cable segment via the respective active optical module that terminates the first active optical cable segment; reading, by a second device, information from a respective active-end storage device included in the respective active optical module that terminates the second active optical cable segment, wherein the second device is connected to the second active optical cable segment via the respective active optical module that terminates the second active optical cable segment; providing, from the first device to an aggregation point at least some of the information read from the respective active-end storage device included in the respective active optical module that terminates the first active optical cable segment; providing, from the second device to the aggregation point, at least some of the information read from the respective active-end storage device included in the respective active optical module that terminates the second active optical cable segment; reading, at a first port that is not included in the first device or the second device, information from a respective passive-end storage device attached to the respective passive end of the first active optical cable segment, wherein the first active optical cable segment is connected to the first port; reading, at a second port that is not included in the first device or the second device, information from a respective passive-end storage device attached to the respective passive end of the second active optical cable segment, wherein the second active optical cable segment is connected to the second port; providing at least some of the information read from the passive-end storage devices to the aggregation point; and authenticating the first and second active optical modules using at least some of information provided to the aggregation point; and wherein the first device and the second device are communicatively coupled to one another via a logical communication path that includes the first and second active optical cable segments.
