An apparatus () for positioning an optical transceiver () relative to a reflector () in a multi-layer circuit board () is presented. The apparatus includes an optical transceiver (), a housing () in which the optical transceiver () is located, a first platform (), a second platform () offset from the first platform (), and a frame () surrounding the second platform (). The first platform () has a first side () and a second side () opposite the first side (). The housing () is attached to the first side (). The apparatus further includes a set of actuators comprising a first actuator (), a second actuator (), and a third actuator (), which are connected to the second side (), and includes a fourth actuator () and a fifth actuator (). Each of the first, second, and third actuators is connected to a first side () of the second platform, and is configured such that each can be controlled to move the transceiver () by moving along a first axis that is orthogonal to the first side of the second platform, thereby moving the first platform (). The fourth actuator () is attached to the frame and is operable to displace the second platform along a second axis that is orthogonal to the first axis. The fifth actuator () is attached to the frame and is operable to displace the second platform along a third axis that is orthogonal to the first axis and to the second axis.
