Method and a system for tuning tunable optical transceivers

A system comprising one or more master tunable optical transceivers and one or more slave tunable optical transceivers, the system is configured to:

• assign, by a master controller, a first wavelength to a first master tunable optical transceiver of the one or more master tunable optical transceivers, wherein the one or more master tunable optical transceivers and the master controller are connected via an Inter-Integrated Circuit (I2C) interface;
• transmit, by the first master tunable optical transceiver, a first optical signal using the first wavelength to a first slave tunable optical transceiver of the one or more slave tunable optical transceiver;
• receive, by a first slave controller, a first interrupt upon receiving the first optical signal at the first slave tunable optical transceiver, wherein the one or more slave tunable optical transceivers and the first slave controller are connected via an I2C interface;
• assign, by the first slave controller, a first wavelength to a transmitting port of the first slave tunable optical transceiver when the first interrupt is occurred for a first time, wherein the first wavelength is finalized for the master controller and the first slave tunable optical transceivers when a feedback optical signal is received by the first master tunable optical transceiver and a first feedback interrupt is registered at the master controller;
• assign, by the master controller, a second wavelength to a second master tunable optical transceiver of the one or more master tunable optical transceivers;
• transmit, by the second master tunable optical transceiver, a second optical signal using the second wavelength to a second slave tunable optical transceiver of the one or more slave tunable optical transceiver;
• receive, by a second slave controller, a first interrupt upon receiving the second optical signal at the second slave tunable optical transceiver;
• assign, by the second slave controller, the first wavelength to a transmitting port of the second slave tunable optical transceiver when the first interrupt is occurred for the first time;
• transmit, by the second slave tunable optical transceiver, a second feedback optical signal using the first wavelength, wherein no signal or interrupt is received by the second master tunable optical transceiver;
• when no interrupt at the second master tunable optical transceiver is received for a first threshold period, disable, by the second master tunable optical transceiver, the transmission using the second wavelength for a second threshold period;
• after disabling the transmission using the second wavelength for the second threshold period, transmit, by the second master tunable optical transceiver, again the second optical signal using the second wavelength to the second slave optical transceiver;
• and
• assign, by the second slave controller, the second wavelength to the second slave tunable optical transceiver when a second interrupt occurs on the reception of the second optical signal after the second threshold period, wherein the second wavelength is finalized for the second master and the second slave tunable optical transceivers when a second feedback interrupt is registered at the master controller.
