Abstract
A method for setting a pluggable optical transceiver, includes: amplifying, with an amplifier, an electrical signal being input to the pluggable optical transceiver from an external device to which the pluggable optical transceiver is mounted, and outputting the amplified electrical signal as a drive signal of an optical modulator; modulating light input from a light source with the optical modulator, based on the drive signal, and outputting the modulated light; monitoring amplitude of the drive signal; and executing a control sequence being set in advance for at least one of the amplifier and the optical modulator when detecting that amplitude of the drive signal exceeds a reference value being set in advance.
Claims12
A pluggable optical transceiver, comprising:
- an electrical signal input unit configured to cause an electrical signal to be input via a connector from an external device to which the pluggable optical transceiver is connected;
- an amplification unit configured to amplify the electrical signal being input via the connector from the external device, and output the amplified electrical signal as a drive signal for performing optical modulation;
- a modulation unit configured to modulate light being input from a light source, based on the drive signal, and output the modulated light;
- an optical signal output unit configured to cause an optical fiber to which an optical signal modulated by the modulation unit is output, to be connected;
- a control unit configured to start to monitor amplitude of the drive signal output from the amplification unit when the pluggable optical transceiver is connected to the external device, and execute a control sequence being set in advance for at least one of the amplification unit and the modulation unit when detecting that the amplitude of the drive signal exceeds a reference value being set in advance;
- and
- a storage unit configured to store the reference value, wherein the storage unit stores the reference value being input from the external device.
