Systems and methods for chirp control of a dual arm z-modulator to minimize dispersion effect of fiber plant

A transceiver configured for chirp control of a dual arm Z-modulator to minimize dispersion in fiber plant, comprising:

• a transmitter configured to transmit an optical signal with modulated data comprising:
• a tunable laser connected to a dual arm Z-modulator;
• and
• a positive driver and negative driver connected to the modulator, wherein
• the positive and negative driver are operable to drive the modulator;
• a receiver configured to receive a second optical signal with modulated data comprising a photodetector connected to a de-multiplexer;
• circuitry connected to the transmitter and receiver configured to transmit and receive data from the transmitter and receiver and to control the transmitter and receiver, wherein the circuitry is configured to add a check sequence which enables a second transceiver to determine errors in the optical signal upon receiving the optical signal;
• and
• a control circuit connected to the circuitry, the modulator, and the positive and negative driver, wherein the control circuit is configured to adjust the gain of one of the positive and negative driver responsive to a control signal received by the receiver, and wherein the control signal is transmitted in the second optical signal by the second transceiver and the control signal comprises error information for the optical signal transmitted by the transmitter to the second transceiver.
