The PPM optical network will be partly evaluated, DOM and timing loop will be evaluated. The ER regime wont’t.
New, dedicated or extra components need to be orderedMore manpower needed to get the work done in a short period of time.
Long leadtimes
Slide11Current status PPM in Antares: Key components
Choice of all components have been made.(INFN/LNS, Nikhef)All the components have been ordered. (INFN/LNS, CPPM, Nikhef
)Parts that are complicated and man power consuming to build, are bought.PPM in Antares: The optical network
11KM3NeT general meeting Catania 20...23-02-2012
Status ey components :Add/drop filters (sub-sea) ordered, exp. Delivery mid March.EDFA’s (sub-sea) ordered, exp. Delivery end March.Lasers and modulators units (Shore St.) ordered,
exp. Delivery end April
Slide12Which tests can be done with available components?
OLT/CLB test using a point to point link with limited fiber length and no EDFA’s. No timing loop available.
Build test bench with limited fiber length, with currently available Add/Drop filters (different λ though) and different modulator setup. No EDFA’s.
Tests with fiber length will be tried with available EDFA’s, optical budget not sufficient?Insert the final EDFA’s in the test bench with fiber length. EDFA behavior?
Full scale PPM in Antares test bench will be build and tested without the DOM but a simple Optical Line Terminal. The last and final test is a full readout with Shore Station DAQ, DOM and complete optical network in.

Start a.s.a.p.
Start after ‘1’
Start mid MarchStart end March
Start mid May
Start end May
Tests are carried out in close cooperation with: INFN/LNS, CEA/Saclay,
CPPM and Nikhef
Slide13YES!
Prepare a PPM network for the Capo Passero site.Optimizing the ER regime for slow control in order to move closer to industrial standards like Fiber To The Home. Assuming that the available industrial solutions are the most reliable and cost efficient. Possibilities are currently investigated.
Study the possibility of HIGH ER instead of low ER because of scalability.Carry out tests with 100km of Capo
Passero fiber and Raman amplifiefication (both supplied by INFN/LNS).
