A fiber optic telecommunications frame is provided including termination
modules positioned on left and right sides of the frame. The frame
further includes left and right vertical cable guides. The frame includes
a horizontal passage linking the left and right panels and the cable
guides. The termination modules hold fiber optic modules with front
termination locations. The fiber optic modules can house couplers, such
as splitters, combiners, and wave length division multiplexers. A
retention mechanism retains each fiber optic module in a partially
removed position from the termination module.
