At the LHC data will be processed at At the LHC data will be processed at approximately 1 Terabit/secondapproximately 1 Terabit/second
Data is transferred over a large Data is transferred over a large number of optic cablesnumber of optic cables
Due to the large number of Due to the large number of connections it is desirable to know connections it is desirable to know the quality of the transmission signalthe quality of the transmission signal

ConclusionsConclusionsWe have developed a SNAP-12 Snooper that checks the signal integrity on Snap-12 fibers
My role included all aspects- design, layout, firmware, and testing.
Signal Detect Test – successfully implemented and verified
Synchronization Test – firmware completed
BIST Test – firmware in progress
Plan is to use in the field by the summer of 2009
