  1. Status of the oSLB project Jose C. Da SILVA LIP-Lisbon

  2. SLB Basic Connection 4 x 1.2Gb cables Trigger Main Board 1 to 9 SLBs (EB) 3 or 4 (EE) RCT Receiver Card (present) SLB-TX ABCD SLB-RX ABCD SLB-TX ABCD SLB-RX ABCD … … SLB-TX ABCD SLB-RX ABCD SLB-TX AB (CD) SLB-RX AB(CD)

  3. Adopted oSLB solution for ECAL Replace 2 SLBs by one “2slot” oSLBUsing 4.8Gb modules RCT uTCA Receiver Card 2x4.8Gb 16TT RCT Receiver Card ECAL EB/EE TCC Board 9 SLBs (EB) 3 or 4 SLBs (EE) Opto PP oRM ABCD oSLB ABCD1 2x4.8Gb spare oSLB ABCD2 … 1or 2 4.8Gb 16TT oSLB ABCD3 oRM ABCD 2or 3 4.8Gb spare SLB AB(CD)4

  4. oSLB “hot points” • Xloom optical solution under study: • 4 TX - 4RX (up to 5Gbps) 500 EURO/Piece • Pro’s: • mechanics, number of channels (4 tx/rx @ 5gbps) • Israeli-CERN fund for (partial) payment || END|| • Open window to study TX or RX versions • Con’s: • Small company issues • Still poor input on these devices (ongoing) • Xloom devices production received(4 units) • BER measurement tests to be done

  5. oSLB “hot points” • Fujitsu “microgiga” optical solution under study: • 4 TX - 4RX (up to 5Gbps) 255 EURO/Piece (!) • Pro’s: • Price • mechanics, number of channels (4 tx/rx @ 5gbps) • Optical Module External to the oSLB • Fujitsu “company name” (2000 units sold) • Con’s: • Infiniband connector dimensions • Modification on front panels mechanics of TCCs • Fujitsu components ordered (4 units) • BER measurement tests to be done • IMPORTANT : • Both solutions have the same Footprint • on the SLBs Artistviewofan SLB + microGigaCNsolution

  6. Production count : ETCC:TPGs uTCA-HTR:TPGs • 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) oSLB RCT/ uTCA GCT/uTCA GT/GMT

  7. Upgrade step 1 HCAL uHTR Cards (Q2 2013 (?) SLHC RCT Cal Trigger Processor Cards (Q2 2012) HCAL Trigger Primitive Optical Splitter (Q?) To DAQ HCAL FE Optical Via BU “AMC13” Optical Ribbons HCAL HTR Cards Regional Calorimeter Trigger ECAL Trigger Primitive Optical Patch Panel (Q2 2012) RXs ECAL TCCs To DAQ oSLBs (Q2 2013) Via GCT ORMs (Q4 2012) (Proto validation Q3 2012) (Series Q4 2012-Q2 2013) Indiv. Fibers (LC)

  9. Optical PP connections Replace 2 SLBs by one 2slots oSLB Using 4.8Gb modules 2x4.8Gb 16TT Opto PP 4 outputs @5Gbps oRM ABCD oSLB ABCD1 1 input @5Gbps 2x4.8Gb spare oSLB ABCD2 1x4.8Gb 8TT LC oSLB ABCDn oRM ABCD oRM ABCD oRM ABCD oRM ABCD oSLB ABCDn oRM ABCD oRM ABCD oSLB ABCDn RCT/ uTCA HTR -uTCA ABCDn

  10. 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

  11. oSLBdesign 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

  12. Next steps: • Bought 4 components (Israeli – Cern Fund) • Bought 4 microGigaCN devices (Fujitsu) • Dev kit from Xilinx (optical receiver) • 2 slots oSLBdesign for Artix-7 Device • oRM dual SFP design looks the best choice to match the oSLB • Validation of the optical devices @ 5Gbps (ongoing) • Production costs funding WG twiki : https://twiki.cern.ch/twiki/bin/viewauth/CMS/ECALSLBOptical
