The 10G TTC-PON: Challenges, solutions and performance

Abstract

The TTC-PON (Timing, Trigger and Control system based in Passive Optical Networks) was first investigated in 2010 in order to replace the current TTC system, responsible for delivering the bunch clock, trigger and control commands to the LHC experiments. A new prototype of the TTC-PON system is now proposed, overcoming the limitations of the formerly presented solutions. A new upstream data transmission scheme relying on longer bursts is described, together with a high-resolution calibration procedure for aligning bursts in a time division multiplexing access. An error correction scheme for downstream data transmission is also discussed.
