Optical receivers choice Production Readiness Review of the TELL 1: O-Rx. Card 2005 5

What is the choice based on? Transmission reliability: Optical data transmission must not degrade operation Bit Error Rate of <10 -15 baseline Confirmation of promised performance in LHCb test Compatibility: Rx-Module must fit on O-Rx. Card Availability: Rx-Modules lead time, product lifetime Price: Competitive price ie. 400 US (500 pc. needed) Production Readiness Review of the TELL 1: O-Rx. Card 2005 6
