CMS Outer Tracker Operational Experience and Performance

The CMS silicon strip tracker, consisting of 15000 silicon modules, with a 200 m$^2$ active area, has been successfully taking data in LHC Run 1 and Run 2. After the second long shutdown period from the end of 2018 the detector resumed operations in the fall of 2021, first with cosmic rays, followed by collisions at 900 GeV, before LHC started regular Run 3 operation at a centre-of-mass energy of 13.6 TeV in summer 2022. The tracker will be operational till the end of LHC Run 3, before the HL-LHC upgrade. In this presentation, the performance of the detector during the Run 2 will be summarized. The projections of the detector performance during Run 3 will be discussed, with particular emphasis on the expected changes in detector performance with increasing irradiation. The performance of the detector during the early Run 3 collisions will also be presented.
