2. PPMs  The Pre-Production Models are deliverables of KM3NeT-PP
PPM of the optical module
PPM of the calibration system
PPM of the readout/DAQ system
PPM of a ‘small scale’ detection unit
Final deliverable: description of the Production Models 

3. PPM-objectives Questions to be answered with these PPMs:
Can we deploy?
Can we calibrate?
Can we measure signals?
Can we get the signals to shore?
Can we measure muon signals?
What do we learn for the PM?
December 2010: Report delivered to EC describing the PPM models (KM3NeT_FL_REP_PPM_description)

4. PPM 20 storeys, 6m bars, for DU distance of 180m
2 storeys with ‘active’ DOMs
To be deployed and connected at….?
