You should not confuse the optical cesiums with optical clocks. Quite 
different spieces. The optical cesiums is still an RF frequency device, 
it is just that magnetics and detection got an optical upgrade. 
Performance wise they are still in the neighborhood of the classical 
cesium beams, compared to the optical transition clocks which is way 
below either of the beam setups, or for that matter the gravity folded 
beam of fountains.
