Multi-channel optical transceiver

An optical transceiver comprising:

• a plurality of dichroic mirrors, each dichroic mirror configured to pass a beam of a first wavelength and reflect a beam of a second wavelength;
• a plurality of laser sources including a first laser source arranged to transmit a first output channel beam of the first wavelength through a first dichroic mirror and a second laser source arranged to transmit a second output channel beam of the second wavelength that is reflected by a second dichroic mirror;
• a plurality of photodetectors including a first photodetector configured to detect a first input channel beam of the second wavelength reflected by the first dichroic mirror and a second photodetector configured to detect a second input channel beam of the first wavelength passed by the second dichroic mirror;
• and
• a plurality of lenses including a first lens arranged to focus the first output channel beam and the first input channel beam and a second lens arranged to focus the second output channel beam and the second input channel beam.

An optical transceiver comprising:

• a laser source configured to transmit an output channel beam having a first optical characteristic;
• a photodetector configured to detect an input channel beam having a second optical characteristic different from the first optical characteristic;
• an aperture through which the output channel beam and the input channel beam pass;
• and
• a beamsplitter, arranged in an optical path of the aperture and the laser source, and configured to pass the output channel beam from the laser source to the aperture and to reflect the input channel beam from the aperture to the photodetector.
