Optical connector and arrangement having one or more transmission surfaces and a surface wiper

An optical arrangement comprising:

• an optical connector comprising a ferrule body having a side face and a transmission surface that is positioned along the side face, the transmission surface facing in a first direction along a signal axis;
• a communication device comprising an optical module having a side face and a transmission surface that is positioned along the side face of the optical module, the transmission surface of the communication device facing in a second direction along the signal axis that is opposite the first direction;
• and
• a surface wiper coupled to the side face of the ferrule body or the side face of the optical module;
• wherein the optical connector and the communication device are configured to mate with each other during a side-mating operation in which the side faces of the ferrule body and the optical module move parallel to each other along a mating axis that is perpendicular to the signal axis, the surface wiper configured to wipe the transmission surface of the opposing side face during the side-mating operation.
