Abstract
An optical communication device comprises an input/output configured to be coupled to an optical communications line, and a passive optical loopback module coupled to the input and configured to receive optical signals from the input/output, the loopback module being further configured to reflect incoming signals of a test wavelength to the input/output.

1-18. (canceled)
An optical network comprising:
- an optical transmitter;
- an optical distribution unit which is optically coupled to the optical transmitter and which comprises a first optical loopback device configured to loop back towards the optical transmitter an optical signal at a first optical test wavelength;
- and
- an optical receiver which is optically coupled to the optical transmitter via the optical distribution device and which comprises a second optical loopback device configured to loop back towards the optical transmitter via the optical distribution unit an optical signal at a second optical test wavelength.
