CLAIMS

What is claimed is:

1. A pluggable active optical module comprising:

an inventory interface at a first end for communicating electrical signals;

one or more optical adapters at a second end for communicating optical signals to/from one or more optical fibers;

a native PLM storage-device interface at the second end, wherein the native PLM storage-device interface is configured to contact a corresponding native PLM storage-device interface on the one or more optical fibers;

one or more optical assemblies for converting electrical signals from the inventory interface into optical signals for transmission over the one or more optical fibers and for converting optical signals from the one or more optical fibers to electrical signals for sending from the inventory interface;

a controller for controlling the one or more optical assemblies;

one or more processing devices coupled to the native PLM storage-device interface and to the inventory interface, wherein the one or more processing devices are configured to access a storage device in one or more optical fibers through the native PLM storage-device interface and obtain physical layer management (PLM) information therefrom,

wherein in response to a request to read a standard table entry the one or more processing devices are configured to provide PLM information to a network element in a format complying with a multi-source agreement (MSA) or a standard for the inventory interface,

wherein in response to a request to read a non-standard table entry, the one or more processing devices are configured to provide PLM information to the network element in a format configured for a physical layer management system.

2. The pluggable active optical module of claim 1, wherein the standard table entry is an address defined by the MSA or a standard for the inventory interface, wherein the nonstandard table entry is an address that is not defined by the MSA or a standard for the inventory interface.

3. The pluggable active optical module of claim 1 , wherein the format complying with the MSA or standard includes including the PLM information in one or more fields allocated by the MSA or standard.

4. The pluggable active optical module of claim 3, wherein the one or more fields include one or more of a required field and a user defined field.

5. The pluggable active optical module of claim 1, wherein the inventory interface complies with the I2C protocol.

6. The pluggable active optical module of claim 5, wherein the standard table entry is one of the OxAO or 0xA2 addresses, wherein the non-standard table entry is one of the 0xA4 or 0xA6 addresses.

7. The pluggable active optical module of claim 1, wherein the format configured for PLM includes a format compatible with a PLM domain management entity in communication with the network element.

8. The pluggable active optical module of claim 1, wherein the format configured for PLM includes a format compatible with decoding at the network element.

9. A system comprising:

a non-native network element having a first port with a first inventory interface; a first pluggable active optical module installed in the first port and coupled to the first inventory interface, wherein in response to a request to read a standard table entry the first pluggable active optical module is configured to provide PLM information to the non-native network element in a format complying with a multi-source agreement (MSA) or a standard for the inventory interface;

an extended network element having a second port with a second inventory interface; and

a second pluggable active optical module installed in the second port and coupled to the second inventory interface, wherein in response to a request to read a non-standard table entry, one or more processing devices are configured to provide PLM information to the extended network element in a format configured for a physical layer management system.

10. The system of claim 9, wherein the extended network element includes:

networking software to provide core networking functionality for the extended network element; and

physical layer management software to provide functionality for the extended network element to send the request to read the non-standard table entry.

11. The system of claim 9, wherein the standard table entry is an address defined by the MSA or standard for the inventory interface, wherein the non-standard table entry is an address that is not defined by the MSA or standard for the inventory interface.

12. The system of claim 9, wherein the format complying with the MSA or standard includes including the PLM information in one or more fields allocated by the MSA or standard

13. The system of claim 9, wherein the inventory interface complies with the I2C protocol.

14. The system of claim 9, wherein the extended network element is configured to decode the PLM information from the second pluggable active optical module.

15. The system of claim 9, wherein the one or more processing devices are configured to report PLM information to a PLM domain management entity in response to receiving updated PLM information from the pluggable active optical module.
