Optical connector with sloped surface

An optical connector, comprising:

• a printed circuit board (PCB) comprising a supporting surface, at least one laser diode, and at least one photo diode, the at least one laser diode and the at least one photo diode positioned on the supporting surface;
• an optical-electric coupling element positioned on the PCB and receiving the at least one laser diode and the at least one photo diode, the optical-electric coupling element comprising at least two first coupling lenses, each of the at least two first coupling lenses aligning with a respective one of the at least one laser diode and the at least one photo diode;
• a jumper detachably connected to the optical-electric coupling element, the jumper comprising a first external sidewall, a second external sidewall facing away from the first external sidewall, a third external surface, and a fourth external surface facing away from the third external surface, the first external sidewall defining a plurality of receiving holes, the third external surface defining a sloped surface extending from the third external surface to the first external sidewall, the third external surface and the sloped surface forming an angle therebetween, the fourth external surface defining a first cavity, the jumper comprising at least two second coupling lenses positioned on a bottom surface of the first cavity, each of the at least two second coupling lenses aligning with a respective one of the at least two first coupling lenses;
• and
• a plurality of optical fibers, each of the optical fibers received in a respective one of the receiving holes.
