Abstract: An electrical connector includes a heat dissipation module with a first end and a second end opposed to the first end and two receptacle connectors located at the second end. The first and second ends define a transceiver-mating direction such that, when a transceiver is inserted into the first end of the heat dissipation module in the transceiver-mating direction, the transceiver mates with one of the two receptacle connectors, and in the heat dissipation module, air flows parallel to the transceiver-mating direction between the first and second ends and flows between the two receptacle connectors.

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 connection includes a first lens with a first strength, a second lens with a second strength weaker than the first strength, a gap between the first lens and the second lenses, and optical fibers that are connected to the first and second lenses and that provide or receive light from the first and second lenses. No intermediate image is formed, and a beam of light in the gap region is either diverging or converging.

Abstract: An interconnect system includes a first circuit board, first and second connectors connected to the first circuit board, and a transceiver including an optical engine and arranged to receive and transmit electrical and optical signals through a cable, to convert optical signals received from the cable into electrical signals, and to convert electrical signals received from the first connector into optical signals to be transmitted through the cable. The transceiver is arranged to mate with the first and second connectors so that at least some converted electrical signals are transmitted to the first connector and so that at least some electrical signals received from the cable are transmitted to the second connector.
