An active optical cable is provided that is well suited for consumer applications. In contrast to known Quad Small Form-Factor Pluggable (QSFP) active optical cables, the active optical cable incorporates at least one consumer input/output (CIO) optical transceiver module that is well suited for consumer applications. The plug housing of the known QSFP active optical cable has been modified to house at least one CIO optical transceiver module that utilizes laser diode and photodiode singlets, rather than the parallel laser diode and photodiode arrays used in the known QSFP active optical cables.
