1. An apparatus, comprising:
a transmitter device configured to:
receive a first signal including a first burst of data;
convert the first signal to a first set of electrical signals;
transmit the first set of electrical signals to a receiver device;
receive a burst absent mode signal from the receiver device, after transmitting the first set of electrical signals to the receiver device, wherein the burst absent mode signal is part of burst absent mode signaling, and the burst absent mode signaling causes the transmitter device to continuously be in a ready state; and
while in the ready state:
receive a second signal including a second burst of data;
convert the second signal to a second set of electrical signals, including a direct current (DC) offset; and
transmit the second set of electrical signals to the receiver device; and
the receiver device configured to:
receive the first set of electrical signals from the transmitter device;
transmit the burst absent mode signal to the transmitter device, after receiving the first set of electrical signals;
detect a presence of the second set of electrical signals; and
in response to detecting the presence of the second set of electrical signals:
remove the DC offset or a portion of the DC offset from the second set of electrical signals to generate an output set of electrical signals; and
cause transmitting the output set of electrical signals to a subsequent device.
