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 module includes a waveguide interconnect that transports light signals; a Silicon Photonics chip that modulates the light signals, detects the light signals, or both modulates and detects the light signals; a coupler chip attached to the Silicon Photonics chip and the waveguide interconnect so that the light signals are transported along a light path between the Silicon Photonics chip and the waveguide interconnect; and one of the Silicon Photonics chip and the coupler chip includes first, second, and third alignment protrusions. The other of the coupler chip and the Silicon Photonics chip includes a point contact, a linear contact, and a planar contact. The point contact provides no movement for the first alignment protrusion. The linear contact provides linear movement for the second alignment protrusion. The planar contact provides planar movement for the third alignment protrusion.
