Optical transceiver and control device

Abstract

Restrict users from viewing and changing the settings of the optical transceiver. [Solution] The optical transceiver includes a register for storing control information relating to the control of the optical transceiver, a register management unit for setting the control information stored in the register in response to remote control from an optical network, a connector including connection terminals for connecting the optical transceiver to a device, and an authentication unit for authenticating that the device connected to the connector is a control device capable of controlling the optical transceiver. The register management unit restricts the reading or modification of the register storing the control information from the device connected to the connector if the authentication unit does not authenticate that the device connected to the connector is a control device.

Claims

1. An optical transceiver that can be remotely controlled from an optical network, A register for storing control information related to the control of the optical transceiver, A register management unit sets the control information stored in the register in response to remote control from the optical network, A connector including connection terminals for connecting the optical transceiver to the device, An authentication unit that authenticates that the device connected to the connector is a control device capable of controlling the optical transceiver, Equipped with, The register management unit, when the authentication unit authenticates that the device connected to the connector is the control device, permits the device connected to the connector to read or modify the register storing the control information. The register management unit restricts the reading or modification of the registers storing the control information from the device connected to the connector if the authentication unit fails to authenticate that the device connected to the connector is the control device. Optical transceiver.

2. The authentication unit performs at least one of a first authentication process and a second authentication process that is different from the first authentication process. The optical transceiver according to claim 1.

3. The first authentication process is a process that determines whether the pattern of the signal output from the control device connected to the connector to the connection terminal matches a specific first pattern. The second authentication process is a process that determines whether the generated information, which is generated based on the pre-authentication information output from the optical transceiver via the connector, matches specific authentication information. The optical transceiver according to claim 2.

4. The aforementioned connection terminals include Tx Disable, RS0, and RS1. The first pattern is a pattern that outputs High or Low from at least one of Tx Disable, RS0, and RS1 in a specific order and timing. The optical transceiver according to claim 3.

5. The authentication unit executes the first authentication process, and if the first authentication process is successful, it executes the second authentication process. The optical transceiver according to claim 3.

6. The control information includes first control information relating to the control of the main signal, second control information relating to the control signal, and third control information which is equipment information of the optical transceiver. The optical transceiver according to any one of claims 1 to 5.

7. The register management unit, if the device connected to the connector is not authenticated by the authentication unit as the control device, prohibits reading or modifying the restricted information which is part of the first control information and the second control information, and permits reading the information from the first control information and the second control information excluding the restricted information and the third control information. The optical transceiver according to claim 6.

8. The output unit outputs dummy information of the restricted information from the connector. The optical transceiver according to claim 7.

9. A control device capable of controlling an optical transceiver that can be remotely controlled from an optical network, A second connector including a connection terminal that can be connected to the first connector provided on the optical transceiver, The optical transceiver includes an output unit that outputs an authentication signal from the second connector used to authenticate that the device connected to the first connector is the control device, Equipped with, The output unit outputs a request from the second connector to read or modify control information stored in a register provided in the optical transceiver. Control device.

10. The aforementioned connection terminals include Tx Disable, RS0, and RS1. The authentication signal includes a second pattern in which High or Low output from at least one of Tx Disable, RS0, and RS1 changes in a specific order and timing. The second pattern is used to compare with the first pattern stored in the optical transceiver. The control device according to claim 9.

11. The control device further comprises a generation unit that generates generated information based on pre-authentication information received from the optical transceiver via the second connector, The authentication signal includes the generated information, The control device according to claim 9.
