In this study spectral and photometric data of the SAX J2103.5+4545 Be/X-ray system are given. The spectral data were taken from June 2007 to September 2008 with the 1.5 m Russian-Turkish telescope, whereas the photometric data were obtained using ROTSE-IIId archive from June 2004 to November 2008. The photometric data up to April 2007 shows that the system was in quiescence in the optical region. But, in the 23rd of April 2007, the system' / s luminosity underwent a large increase, which is in agreement with X-ray data. This increase was approximately 1 mag. Also, the Halpha line was displaying an emission with increased equivalent width proportional to the outburst. Afterwards, the Halpha line profile changed from a double peaked emission into a single peaked absorption, which is in agreement with the system' / s structure. This means that the Be star threw away its disc and its light curve fell back to its old luminosity.
