Abstract
There is provided a method for testing an optical fiber link. The method includes employing a wavelength division multiplexer (WDM) to receive a signal via a port of the WDM and multiplex the signal onto the optical fiber link. The signal is used in a test of the optical fiber link. There is also provided an arrangement of components for testing the fiber link.

A method for testing an optical fiber link, comprising:
- employing a wavelength division multiplexer (WDM) to receive a signal via a port of said WDM and multiplex said signal onto said optical fiber link,
- wherein said signal is used in a test of said optical fiber link.
An arrangement for testing an optical fiber link, comprising:
- a wavelength division multiplexer (WDM) for receiving a signal via a port of said WDM and multiplexing said signal onto said optical fiber link,
- wherein said signal is used in a test of said optical fiber link.
A method for testing an optical fiber link, comprising:
- employing a wavelength division multiplexer (WDM) to couple a test signal between a first port of said WDM and said optical fiber link, and to couple a communication signal between a second port of said WDM and said optical fiber link,
- wherein said test signal is used in a test of said optical fiber link.
An arrangement for testing an optical fiber link, comprising:
- a wavelength division multiplexer (WDM) for coupling a test signal between a first port of said WDM and said optical fiber link, and coupling a communication signal between a second port of said WDM and said optical fiber link,
- wherein said test signal is used in a test of said optical fiber link.
