Abstract
A communications arrangement includes incoming and outgoing fiber optics cables, each having one end inside a confined space and another end outside of the confined space, with the incoming fiber optics cable transmitting light from outside of the confined space, to inside the confined space, through a gap and through a movable filter to the outgoing fiber optics cable, such that a user inside the confined space can transmit signals from inside the confined space to outside of the confined space by moving the movable filter.
