More complex than LHC-more cables-more connectors-complex environment-many users to interface to
Work can be done, but TS/EL/OF can only manageso much!

What an Experiment gets from us:What an Experiment gets from us:
professional advice, supplies and installations customized and engineering solutions 2 year warranty on the installations operational service with specialized instrumentation
but:
good supplies and work have a price! it needs to be well organized, planned and managed last minute jobs are possible, but should not be the usual way of working

Optical patch-cords, cables, connectionsOptical patch-cords, cables, connections
A large variety of patch-cords and cables exist in the contract (already over 200)
Any optical patch-cord or cable can be supplied
Above items are not in CERN store!
Quality of optical connections is difficult to check and should be left to professionals!
TS/EL/OF is equipped for and capable of performing this work

To summarizeTo summarize
TS-EL-OF and the B1201/TS/LHC contract provide a professional service to the experiments.
The Experiments can make use of the blanket purchase and installation contract: blanket envelope 4 MSfr. project(s) need to be defined, budgetized and planned combined workload is more than can be managed by
the available staff since the part done for the experiment is far more
complex than the LHC part, we consider it reasonable to request support from the PH department
