Genova Autonomous DAQs

• Equipped with SAFT, 130 Ah Lithium batteries
• in LCM container
• (OK for 70 hours of continuous operation.)
• Switch on the system at the moment of 1st
  deployment
• Download data at the moment of the recovery after
  24 hours
• Switch off the system to save power
• Switch on again at the moment of the 2nd
  deployment
• ? batteries exhausted.

OPM

• Two fibre-optic test systems
• 3 Local optical power meters
• Combination of OPM and voltage-sensing Tinytag
• (synchronization a problem?)
• each OPM Uses 2 fibres in 1 of the 3 tubes
• (2) Remote optical power meter /OTDR
• DAQ Tx, Rx fibres from JB and IL
• spliced directly to fibres in EMC cable
• uses 4 or 5 fibres in each of the 3 tubes
• (1 fibre in EMC not tested)
• 2 fibre coils in SPM case,
• CLK1, CLK2 not looped back in SPM case
• (might affect CK needed for MILOM etc)
