oSLB “hot points”

4

• 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

oSLB “hot points”

5

• 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

Production count :

• 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)

Optical PP : MTP/LC/MTP

10

• 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

oSLB design and Schedule

11

• “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

José C. Da SilvaCMS Upgrade Week Workshop, 7 -10 November 2011 12

Next steps:

• Bought 4 components (Israeli – Cern Fund)

• Bought 4 microGigaCN devices (Fujitsu)

• Dev kit from Xilinx (optical receiver)

• 2 slots oSLB design 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
