An array of fiber optic splicing cassettes. The array has first and second
side plates connected to one another by first and second axes. The fiber
optic splicing cassettes each have a base and first and second curved
slots in the base. Each of the first slots is moveably engaged on the
first axis, and each of the second slots is moveably engaged on the
second axis. In this way each of the cassettes may be moved between an
open position and a closed position by simultaneously moving the first
and second slots in one of the cassettes relative to the first and second
axes.
