Low debris dust cap for MPO connectors
A low debris dust cap has a plurality of portions corresponding the fiber optic connector on which it is installed. Two latches extending from side walls are disposed between the inner and outer housings. The low debris dust cap can be placed and removed from the connector without movement of either the inner or outer housings.
