Abstract
A compact optical transceiver is provided by using a serial communication bus as a communication bus connecting a logic device and a microcomputer. This optical transceiver is connected through an MDIO bus to an external upper layer and is provided with a microcomputer, a logic device, the MDIO bus, a serial communication bus, and a first dedicated signal line. The microcomputer has an MDIO register. The logic device receives a command code, address information, and a single data block from the upper layer through the MDIO bus, transmits the address information and the single data block to the microcomputer through the serial communication bus, and transmits the OP code to the microcomputer through the first dedicated signal line.
Claims10
An optical transceiver able to communicate with an external upper layer through an MDIO bus, the optical transceiver comprising;
- a microcomputer configured to monitor and control an internal state of the optical transceiver;
- and
- a logic device configured to receive a command code, address information, and a single data block from the external upper layer through the MDIO bus, transmit the address information and the single data block to the microcomputer through a serial communication bus, and transmit information of the command code to the microcomputer through a first dedicated signal line independent of the serial communication bus.
