| 摘要 |
An optical apparatus for use in an optical communications network, and a method of operating a network are described. The apparatus includes an input suitable for receiving a first continuous wave optical signal from a remote location on a network, and a modifying unit arranged to modify the first continuous wave optical signal to produce a second continuous wave optical signal having a wavelength which is different from the wavelength of the first continuous wave optical signal. A modulating unit is arranged to modulate the second continuous wave optical signal with data to produce a modulated second continuous wave optical signal.
