Abstract
An active optical cable is disclosed. According to the present disclosure, there is provided an active optical cable, having no complicated structure by obviating the need for a separate monitoring photodetector as was used for a typical optical transceiver, increasing light output-current linearity to improve optical coupling efficiency, generating a library of transmission/reception-related electro-optical characteristics of both optical modules so as to enable light outputted from a light source included in an optical transmitter to maintain high linearity over a wide range of temperatures, thereby reducing power consumption, and being applicable to a multi-level PAM technique involving at least four (4) levels.
