  1. The Versatile TransceiverTowards Production Readiness CsabaSoos on behalf ofManoelBarros Marin, StéphaneDétraz, Lauri Olanterä, Christophe Sigaud,Sarah Storey, Jan Troska, François Vasey, Paschalis Vichoudis CERN PH-ESE-BE

  2. Outline • Introduction • VTRx and VTTx prototypes • Test results • Towards production • Strategy • Production testing • Something new • Summary Versatile Transceiver - Towards Production Readiness

  3. Versatile Link Project • Optical layer linking front-end to back-end up to 150 m distant. • Bi-directional @ 5 Gbps • Two Point-to-point solutions • 850 nm Multimode • 1310 nm Single-mode • Front-end pluggable module • Rad-hard front-end • Joint Project Proposal submitted to ATLAS & CMS upgrade steering groups in 2007 and endorsed in 2008 • Project Kick-off: April 2008 • Phase I: Proof of Concept (18mo) • Phase II: Feasibility Study (18mo) • (Consolidation) • Phase III: Pre-prodn. readiness (18mo) Versatile Transceiver - Towards Production Readiness

  4. Fully Functional Prototypes Versatile Transceiver - Towards Production Readiness

  5. Single-mode VTRx TX Eye TX Eye of 2011 vintage RX Eye Versatile Transceiver - Towards Production Readiness

  6. Multi-mode VTRx TX Eye TX Eye of 2011 vintage RX Eye Versatile Transceiver - Towards Production Readiness

  7. Multi-mode VTTx TX Eye Channel 2 TX Eye Channel 1 Versatile Transceiver - Towards Production Readiness

  8. Towards Production • Next steps • Propose purchasing strategy for LHCb, CMS HCAL, CMS Pix phI, ATLAS SmWh and ATLAS LArg upgrade • Quantities: 7750VTTx, 1150 MM VTRx, 200 SM VTRx, 3000 SM TOSA • Cost estimates (CHF): VTTx149, MM VTRx199 , SM VTRx249 • Firm prices by mid 2013 • Procurement procedure with tentative schedule • Quality assurance • Qualification (all components) • Lot acceptance/validation (all components) • Production testing (all manufactured modules) • Test procedures for the above are being prepared Versatile Transceiver - Towards Production Readiness

  9. Production Test Procedure • Verify that manufactured modules meet the Versatile Link Specifications, Part 2.1 (EDMS 1140665) • Static: Light-current curve (LI) • Dynamic: Transmit Optical Eye (TP2), Receive Electrical Eye (TP4), Receiver sensitivity (BER) • Test cycle should be optimized • No changes in electrical/optical connections between cycles • Target bit error rate of 10-10 instead of 10-12 • Measuring transmitter while receiver sensitivity is measured • Test automation and report generation • Results to be stored in a database Versatile Transceiver - Towards Production Readiness

  10. Instrument-based Test System Oscilloscope DUT Pattern generator & error detector Ref. TRx Variable Optical Attenuator & Power Meter Versatile Transceiver - Towards Production Readiness

  11. FPGA-based Test System Variable Optical Attenuator + Power Meter Reference RX FPGA + DUT Oscilloscope Versatile Transceiver - Towards Production Readiness

  12. Small Footprint VTRx • Footprint constraint • 45 x 15 x 8 mm3 • Must include serializer (GBTX, 10 x 10 mm2) • Keep stand-alone module concept • Easier prototyping and maintenance • Reuse work done in the framework of the Versatile Link project • CMS tracker Phase II upgrade • Need low profile optical interface for the new front-end hybrid Versatile Transceiver - Towards Production Readiness

  13. SF-VTRx Prototype SF-VTRx and its test board SF-VTRx versus Multi-mode VTRx RX Eye TX Eye Versatile Transceiver - Towards Production Readiness

  14. Summary • Versatile Link moves to pre-production readiness phase • Fully functional VTRx and VTTx prototypes have been manufactured and tested • Specifications are met • Test procedure is being established • Test setup is being discussed • New VTRx form factor has been introduced: SF-VTRx • Further size reduction mightbe needed • That will be difficult to achieve using standard LC TOSA/ROSA parts • More aggressive packaging options will be investigated Versatile Transceiver - Towards Production Readiness

  15. Test system • Pattern generator and error detector (PG and ED) • Bench-top instrument, or • FPGA-based (e.g. GLIB) • Precision clock source • High-speed oscilloscope • Sampling scope with optical head • Real-time scope with reference receiver • Variable Optical Attenuator (VOA) • Optical Power Meter (PM) • High-speed analog switch • Optical switch Versatile Transceiver - Towards Production Readiness
