Optical connector assembly

An optical connector assembly for connecting a first optical printed circuit board to a second electro optical printed circuit board, the connector assembly comprising a first part for arrangement on the first optical printed circuit board and a second part for arrangement on the second optical printed circuit board, the first part comprising:

• a first electrical connector;
• and an optical connector;
• the optical connector being arranged in a housing that is fixed relative to the first electrical connector, the optical connector being movably mounted in the housing so that the optical connector can move relative to the electrical connection, such that when electrical connection is made, the optical connector can still move with at least three degrees of freedom;
• an optical component within the optical connector, having one or more transmitting or receiving collimating lenses;
• and, the second part comprising:
• a second electrical connector;
• and an optical engine;
• an optical engine cover fixed relative to the optical engine, the optical engine cover having an opening through which light can be received by or transmitted from the optical engine, guidance components to engage with the first optical connector of the first part, the second electrical connector and the optical engine being fixed relative to each other, the optical engine having one or more transmitting or receiving collimating lenses aligned in use with the one or more receiving or transmitting collimating lenses of the first part.
