Versatile Link
Template TRx: SFP+ Transceiver
● Bi-directional Module with connector interface● Based upon an acknowledged standard
● Work with Industrial partner early-on
● MM 850nm & SM 1310nm versions
● Bitrate 2.5 – 10 Gbps
● Fast access to hardware
● Easy distribution to integrators
● Customization in second step

Versatile Link
Evolution: Front End Transceiver, VTRx
● Low Mass & Volume● Minimize material, avoid metals
● Non-magnetic, capable of operating in a magnetic field
● Requires replacement of ferrite bead used in laser bias network
● Bitrate determined by ASICs: 5 – 10 Gbps
● 850nm and 1310nm flavours

Versatile LinkThe Versatile Link Project Roadmap
● Project proposal submitted to ATLAS and CMS SLHC upgrade steering groups in Nov07
● Project endorsed by ATLAS and CMS in early 2008
● Kick-off Meeting 10 Apr 2008
● 3 phases of 18 months each● phase 1 proof of concept based on tentative specifications, partial tests and early prototypes
● Apr08 – Sep 09● Phase 1 closeout meeting 20th Sept
● Phase 2: feasibility demonstration based on complete specifications and exhaustive tests on final prototypes
● Oct 09 – Apr11● Specs and procedures● Tests and Results● List of COTS components and suppliers● Test-systems and Prototype custom components
● Phase 3: specifications freeze, pre-production readiness, technico-commercial actions● Apr11 – Oct12
