Production count : RCT/ uTCA GCT/ uTCA GT/GMT ETCC: TPGs uTCA-HTR: TPGs oSLB produce ONLY the final count (ECAL) of oSLBs + spares 1 to 1 = 324 EB, 252 EE (576) 2 or 1 = 180 EB , 180 EE (360) = ~200 Links gain!! 3 or 2 = 108 EB (3), 144(2) EE (252) = ~320 Links gain!! (~500-700 euros savings per oSLB) Cost effective! ~200Euro/ oSLB + 255 USD /microgiga adaptor Cost estimate:~ 500 Euro / oSLB/optics + 30K USD for optical bundles and adaptors production covers the ECAL final needs (400Pcs) Production numbers and cost

Optical PP : MTP/LC/MTP MTP 12 to LC to MTP12 optical adaptors to match SLB-RCT inputs Xloom device has guide pins (MTP “female” bundle) Cost (based on 2007 prices) 12-way fan-out 3 or 10 meters – ~350 USD/each 12-way adapters – 65 USD/each conclusions

oSLB design and Schedule “Dual input” SLB Layout Use latest FPGA technology : Artix 7 3v3 Compatible with present design Reduced impact on design Reduce costs <200 USD / Artix 7 Artix 7 Available in May 2012 Rev A Prototype validation up to August 2012 (10 units) SLB test bench installation in 904 (started) Integration with TCCs and oRMS -> Oct-Dec 2012 (904) RevB ? oSLB production done in June 2013 ( ~6 months) * P5 installation from August 2013 onwards * If LHC machine operation schedule changes we SHOULD delay the oSLB production conclusions
