Abstract: A method for determining receiver coupling efficiency includes varying optical power inputted into a half active optical cable to determine a maximum optical power at which the TIA squelches and determining a receiver coupling efficiency by calculating a ratio of a threshold optical power to the maximum optical power at which the TIA squelches. A method of determining link loss in a channel includes varying optical power of a light source to determine the maximum optical power at which the TIA squelches and determining the link loss in the channel by subtracting the maximum optical power from the threshold optical power. A method of determining link topology includes selecting a pattern of optical powers and matching a pattern of squelched and non-squelched outputs with the pattern of optical power. An active optical cable includes memory storing a value related to an initial link loss of the active optical cable.

Abstract: An optical block includes a first surface that receives light entering the optical block, a second surface through which the light exits the optical block, and a reflector that reflects light from the first surface towards the second surface. The reflector includes a textured surface that scatters or absorbs some of the light received from the first surface to attenuate the light exiting the optical block through the second surface.
