Bi-directional optical communication modules and cables

A bi-directional optical communication cable comprising:

• a first substrate;
• a first filter supported by the first substrate;
• a first optical transmitter supported by the first substrate and communicably coupled with the first filter, the first optical transmitter configured to emit a first pre-determined wavelength band;
• a first optical receiver supported by the first substrate and communicably coupled with the first filter, the first optical receiver configured to detect a second pre-determined wavelength band,
• a second substrate;
• a filter supported by the second substrate;
• a second optical transmitter supported by the second substrate and communicably coupled with the filter, the second optical transmitter configured to emit the second pre-determined wavelength band;
• a second optical receiver supported by the second substrate and communicably coupled with the filter, the second optical receiver configured to detect the first pre-determined wavelength band;
• and
• an optical communication medium communicably coupling the first filter and the filter.

A method of manufacturing a bi-directional optical communication module, the method comprising:

• providing a substrate;
• supporting a first filter on the substrate;
• supporting a first optical transmitter configured to emit a first pre-determined wavelength band on the substrate;
• communicably coupling the first optical transmitter with the first filter;
• supporting a first optical receiver configured to detect a second pre-determined wavelength band on the substrate;
• communicably coupling the first optical receiver with the first filter,
• wherein the first filter is configured to:
• pass optical signals received from the first optical transmitter associated with the first wavelength band into an optical communication medium;
• and
• direct optical signals received from the optical communication medium associated with the second wavelength band into the first optical receiver.
