1. A system, comprising:
a transmitter module, configured to generate an output signal for transmission through electromagnetic radiation, and the transmitter module comprising:
a first converter, configured to convert data carried in a first type of data link layer protocol data unit to data carried in a second type of data link layer protocol data unit;
a forward error correction encoder, configured to encode the converted data (which is converted by the first converter), using a forward error correction encoding process, wherein the encoding of the data is rateless; and
a modulator, configured to modulate the encoded data to generate the output signal; and
a receiver module, configured to generate data carried in the first type of data link layer protocol data unit from an input signal received through electromagnetic radiation, and the receiver module comprising:
a demodulator, configured to demodulate the input signal to generate demodulated data;
a forward error correction decoder, configured to decode the demodulated data using a forward error correction decoding process, wherein an output of the forward error correction decoder comprises data carried in the second type of data link layer protocol data unit, and wherein the decoding of the data is rateless; and
a second converter, configured to convert the decoded date, carried in the second type of data link layer protocol data unit, to data carried in the first type of data link layer protocol data unit; and
wherein the input signal received through a laser beam and the output signal is transmitted through a laser beam; and
wherein the input signal and the output signal are communicated at ten thousand or greater optical communications terminal (OCT) frames per ten milliseconds or at least one million OCT frames per second.
