  1. Optical Data Transmission in LHCb Cassette Fibre Breakout VCSEL-SMA GOL XILINX FPGA 12-way MTP/MPO ~ 100m Agilent HFBR-7XX Agilent HFBR-7XX TLK 2501 Opto WG, TWEPP2011

  2. Problem: VCSEL deaths (see Opto WG March 2011) As of Sept 2011, 1.8% of VCSELs died (and replaced) Silicon Tracker (IT+TT) most affected (2000 VCSELs) 1 – 2 deaths per month Opto WG, TWEPP2011

  3. Decision: Death rate is ‘acceptable’ Regular repairs during technical stops – detectors are accessible New batch of spares purchased from vendor : no further action planned Opto WG, TWEPP2011

  4. Upgrade plans Triggerless readout: zero-suppress on front-end Use GBT + Versatile Link: ~ 11,000 data links + TTC/Slow-control Opto WG, TWEPP2011

  5. Upgrade R&D Dual transmitter SFP+ is a big advantage Happy to collaborate with Versatile Link project to advance this • Back-end board (TELL40): • Jean-Pierre Cachemiche et al • Dense connectors on • mezzanine card: • 24 input data links (4.8 Gbit) • + 12 x 10GB-ethernet to DAQ Opto WG, TWEPP2011
