Slide 2: full optical , can be used with OLD or NEW RCT and ECAL/HCAL designs, but needs FULL oSLB production in case HCAL does not upgrades in time.
a “copy” link can be used for RCT uTCA validation.

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 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
Xloom solution

5. Artist view of an SLB + microGigaCN solution
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 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
Fujitsu solution , external to oSLB

6. 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!!
(~ euros savings per oSLB)
Cost effective!
~200Euro/ oSLB USD /microgiga adaptor
Cost estimate:~ 500 Euro / oSLB/optics
+ 30K USD for optical bundles and adaptors
production covers the ECAL final needs (400Pcs)

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
conclusions

11. 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

12. WG twiki : https://twiki.cern.ch/twiki/bin/viewauth/CMS/ECALSLBOptical
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 5Gbps (ongoing)
