ST-EL-OF / L K de Jonge

the optical network policy
The optical network policy
  • The CERN Optical Network is built of Optical Trunks connecting STAR points
  • IT and ST plan the Optical Network together
  • The optical fibres in and between STAR points are managed and allocated by IT-CS
  • Individual fibre usage (dark fibres) out of a STAR point is handled by ST-EL
  • Users shall use the IT-CS IP/Ethernet Network for all their Communications needs

The “Lame Vibrante” at work

The machine advanced at a speed of about 60 cm per minute and left a clean field behind.

One must of course be absolutely sure that no obstacles, like water supplies or electrical cables are on its way.

Optical fibre cabling
  • SURFACE
  • SURFACE TO UNDERGROUND (SHAFTS)
  • TUNNEL
  • BEAM INSTRUMENTATION
  • EXPERIMENTAL AREAS

surface optical links from pcr
Surface optical links from PCR
  • Sites 1, 5, 6,7, 8, 513 and CNGS OK
  • Sites 2, 32, 33 and 4 to be done
  • Old HDPE ducts to above sites in bad state
    • they are in place since 1986
    • ducts to P6 had (have) to be replaced
    • ducts to P8 had to be repaired at several spots
  • Blowing of cables difficult/impossible

ST-EL-OF / L K de Jonge

slide8

Optical cabling with tube systems

  • Install (blow) guide tubes (low cost)
  • Blow mini optical cables on demand
  • Modular and Flexible
  • Outdoor resistant
  • Easy to replace cables
  • Lower initial cost

Blowing of guide tubes

ST-EL-OF / L K de Jonge

slide10

Blowing of mini optical fibre cables

  • This Micro-Jet can blow mini optical fibre cables with

(1- 72) fibres.

  • Size of an A4 sheet and 10 cm high.
  • Several units can be cascaded.
  • Blowing pressure is 10 Bar.

Micro-Jet from Plumettaz/CH

Ø 18 mm duct with 3 x Ø 7 mm guide tubes

Capacity 3 x 24=72 optical fibres

3 ducts types with guide tubes

ST-EL-OF / L K de Jonge

slide13

Installation principles

  • Ø 40 mm duct with 10 guide tubes between SR and US/UJ
  • Ø 40 mm duct in the LHC tunnel with stops at US/UJ and partial stops at the alcoves RE
    • duct fixed together with leaky feeder cable to tunnel wall
  • Ø 25 mm duct for SL-BI and medium installations
  • Ø 18 mm duct for low capacity installations
  • Once the above infrastructure is in place, the mini optical cables can be blown
  • The tunnel fibres must be replaceable in case of radiation damage

Optical patch cords

  • Very large quantities of various optical patch cords will be required
  • The Market Survey indicated 10’000
  • We must know from you what you want and how many you want
  • Any patch cord type is possible

ST-EL-OF / L K de Jonge

slide21

Optical fibre management

  • With such a dense optical network, we need to manage it
  • We are actually studying ways how to integrate our data into a common data base which should be linked to geographical information
  • We want make make use of the existing geographical information systems (GIS) and databases
