A multi-channel optic system including an optic device physically configured so as to potentially provide a predetermined function in relation to a maximum number of optical channels at different frequencies; and a control device which is adapted to reversibly disable the optic device in relation to a selected number of the optical channels and thereby limit the number of optical channels for which the predetermined function is provided to a number less than the maximum number, and which is upgradeable so as to provide the predetermined function for an increased number of optical channels. |
