Abstract
An optical communication device includes an optical transmitter configured to transmit data over an optical link. The optical communication device also includes a memory having a configuration location of one or more bytes, and one or more registers storing a default transmit power value. The optical communication device also includes a controller configured to access the configuration location. In response to determining that no valid transmit power value is indicated by information stored in the configuration location, the controller accesses the one or more registers to read the default transmit power value, and sets a transmit power level of the optical transmitter to the default transmit power value.
Claims20
An optical communication device comprising:
- an optical transmitter configured to transmit data over an optical link;
- a memory comprising:
- a configuration location comprising one or more bytes;
- and
- one or more registers storing a default transmit power value;
- and
- a controller configured to:
- access the configuration location;
- and
- in response to determining that no valid transmit power value is indicated by information stored in the configuration location:
- access the one or more registers to read the default transmit power value;
- and
- set a transmit power level of the optical transmitter to the default transmit power value.
An electrically erasable programmable read-only memory (EEPROM) for an optical transceiver compliant with at least one 400ZR or 400ZR+ implementation agreement, the EEPROM comprising:
- an application register storing information accessible by a controller of the optical transceiver, wherein the information indicates at least a transmit power value associated with a media interface type supported by the optical transceiver;
- and
- one or more registers storing a default transmit power value for the optical transceiver, the one or more registers being custom registers of page 01 h of the EEPROM, and wherein the default transmit power is based at least in part on a type of the optical transceiver.
A method of configuring an optical transceiver compliant with at least one 400ZR or 400ZR+ implementation agreement, the method comprising:
- accessing a configuration location of a memory of the optical transceiver;
- and
- in response to determining that no valid transmit power value is indicated by information stored in the configuration location:
- accessing one or more registers of an electrically erasable programmable read-only memory (EEPROM) of the memory to read a default transmit power value stored in the one or more registers;
- and
- setting a transmit power level of an optical transmitter of the optical transceiver to the default transmit power value.
