The invention relates to an optical connector comprising a substrate, a plurality of optical channels, a light source, a beveled structure and a light detector. The optical channels are used for transmitting optical signals. The light source arranged on the substrate is used for transmitting a first optical signal. The beveled structure has an optical reflective surface to reflect the first optical signal emitted by the light source to at least one of the optical channels. The light detector arranged on the substrate is used for receiving a second optical signal emitted from at least one of the optical channels. The optical reflective surface has at least one gap, so that the optical reflective surface is separated into at least two sections by the gap and the segmented sections are not connected electrically. The topical connector has effects of low electromagnetic crosstalk and low noise interference.
