An optical link includes an optical fiber (35) for transmission of signals and has from an electrical input terminal to an electrical output terminal a frequency dependent loss and phase linearity characteristics that are equal or similar, for at least a particular or predetermined frequency region, to a specific length of an electrical cable such as a twisted pair cable regardless of the actual length of the optical fiber, naturally within certain but rather wide limits. The optical link may for this purpose include specially selected components or compensating devices such as filters (41) or other devices configured in a suitable way. |
