FIBRE UNIT MAIN ACTIVITIES:
In collaboration with CERN users, design and manage the optical fibre infrastructure
Establish and manage industrial contracts for the supply and installation of passive optical fibres components A large contract for supply and installation of all standard
components (fibres, cables, terminal equipment, patchcords)
Large contracts for supply of RAD-RESISTANT fibres (~ 2500 km) plus cabling (~100 km) within existent frame contract
Qualification, quality assurance and quality control of specialty optical fibres and new passive optical components through frame contract. Laboratory equipped with microscopes, interferometers,
OTDR, insertion loss/return loss meters for single and multi-fibre connectors.
CERN Safety Instructions Compliant Standard Passive Solutions for all CERN users

INDUSTRIAL SUPPLY CONTRACT SPECIFICATIONS: Detailed requirements on
Compliance with ITU-T international standards
Radiation resistance and optical properties
Spool minimum lengths, tracking, etc. 2500 km procured in 2006 plus 2400 km
procured in 2012 (~150 km/month)
A QUALITY ASSURANCE PLAN, WITH EXTENSIVE QUALITY CONTROL WAS PUT IN PLACE: Extensive fibre qualification tests
performed during 2 years before contract placement
Each preform was tested (radiation). Implemented cabling and fibre
tracking system at both manufacturer's and CERN
Qualification and procurement of Radiation Resistan Fibres
