Homodyne bidirectional optical transceiver

An optical communication system comprising:

• a first optical transceiver comprising:
• a first receiver,
• a first transmitter, and
• a light source configured to output a light signal;
• a second optical transceiver comprising:
• a second receiver, and
• a second transmitter, wherein both the first transmitter of the first optical transceiver and the second transmitter of the second optical transceiver modulate signals generated by the light source of the first optical transceiver.

An optical communication system comprising:

• a first optical transceiver comprising:
• a first receiver,
• a first transmitter,
• a first light source configured to output a first light signal at a first wavelength,
• a first fiber optic tap, and
• a first light emitting diode (LED), wherein
• the first fiber optic tap is configured to siphon a portion of an input signal, received via a fiber cable, at the first optical transceiver, and
• the first LED is configured to emit light based on the portion of the input signal having an intensity above or below a threshold value.

An optical communication system comprising:

• a first optical transceiver comprising:
• a first light source configured to emit a light signal at a first wavelength,
• a second light source configured to emit a light signal at a second wavelength, and
• a first controller configured to control only one of the first light source and the second light source to be operational at a time;
• a second optical transceiver comprising:
• a third light source configured to emit a light signal at the first wavelength,
• a fourth light source configured to emit a light signal at the second wavelength, and
• a second controller configured to control only one of the third light source and the fourth light source to be operational at a time, wherein
• the first controller is configured to control the first light source and the second light source and the second controller is configured to control the third light source and the fourth light source, respectively, such that the first light source and the third light source are not operational at a same time and the second light source and the fourth light source are not operational at a same time.
