CMS General Comment
Optical fibres (TTC, BST) installed by TS-EL-OF generally require a patch panel to terminate them. This cannot go in S1E03, but could find place in S1E09? The installation of these same fibres have been requested of TS-EL-OF by Sophie Baron (PH/ESS).
[1] TTC Fibres for CMS go directly via the Machine Tunnel from Point 4 to Point 5, they do not pass the CCC/R as for the others
[2] BST Fibres are two per ring
[3] Original arrangement between B. Puccio (AB/CO) and E. Sbrissa (PH/DT1) was that E. Sbrissa would install the correct cable between the BIC and his CIBU. E. Sbrissa is ok with someone doing it for him, however, and will supply the final rack location ASAP.
