METHODS FOR DETERMINING RECEIVER COUPLING EFFICIENCY LINK MARGIN AND LINK TOPOLOGY IN ACTIVE OPTICAL CABLES

摘要

A method of measuring the receiver coupling efficiency includes measuring the maximum optical power that the TIA squares by changing the optical power input to the half active optical cable and calculating the ratio of the critical optical power to the maximum optical power that the TIA squares, Including measuring coupling efficiency. A method of measuring a link loss in a channel includes measuring a link loss in the channel by calculating a maximum optical power that is squatted by the TIA by changing the optical power of the light source and removing the maximum optical power from the critical optical power . The method of measuring the link topology includes selecting a pattern of optical power and matching the pattern of the optical power with the pattern of the squared and unscrewed outputs. The active optical cable includes a memory storing a value related to an initial link loss of the active optical cable.;
