Lavspenning/Kabler/Fiberoptisk kabel - G2-SM 9/125 QENI

1 SCOPE

1.1 Use

The single mode optical fibre cables are recommended for installation in ducts and tubes in outdoor environment.

1.2 Purpose

The purpose of the technical specification is to provide guidance for the production, test procedures and delivery of products according to stated requirements. The technical specification contains technical and functional requirements to be fulfilled.

The cables shall provide capability to transfer information signals. The cables shall be free of halogens and metallic elements. The cables shall withstand relevant loads that may be present.

Q (1. letter) = optical fibres in tube(s) with filling compound
E (2. letter) = inner sheath of polyethylene
N (3. letter) = steel tape
I (4. letter) = outer sheath of halogen-free polymer (self-extinguishing)

1.3 History

First edition.

2 REQUIREMENTS

2.1 Optical requirements for the fibres

a) Optical fibres shall be single mode fibres according to ITU-T G.652.D (Table 4/G.652 - G.652.D attributes) with dimensions 9/125 µm.

2.2 Cable types and mechanical requirements

a) The following mechanical requirements apply for ordinary optical fibre cable:

Number of optical fibres (♦♦)	Use	Designation	F.number	Diameter (mm)	Bending diameter (mm)	Max. static tension (kN)	Max. tension installation (kN)	Weight (approx.) (kg/km)	Crush (plate/plate) (kN)	Crush (plate/mandrel) (kN)
2	Duct	G2-SM 9/125 QENI	To be stated	15	300	1,5	0,5	160	2,0	1,5

F.number is an uniqe 9-digit number identifying the specific production variant.

2.2.1 Primary cladding and colour code

a) The optical single mode fibres shall have a primary cladding.

1. The minimum diameter of the primary cladding shall be 250 µm.
2. The colouring of the primary cladding shall be durable and resistent to cleaning aids.
3. It shall be easy to clean off the primary cladding with natural means without health risk. The means and method shall be provided.

b) The primary cladding shall be coloured according to the colours defined in IEC 60304. The following colour code shall be used:

Fibre number	1	2
Colour	White	Red

2.2.2 Secondary protection (tube)

a) The two optical fibres with primary cladding and a filling compound (for water protection) shall be contained in a tube.

b) The filling compound shall be easily removeable by natural means without health risk. The means and method shall be provided.

2.3 Cable construction

a) The cable shall have a central strength member (FRP) of 30 mm.

b) A layer structure around the central strength member shall contain:

1. The tube with the two fibres.
2. Five fill elements with the same diametre as the tube.

c) A concentric inner sheath of PE of minimum 0,8 mm

1. A rip thread should be added under the inner sheath.

d) A steal tape of minimum 0,2 mm shall be wrapped (with full overlap) around the cable kernel.

e) The outer sheath shall be minimum 1,5 mm black flame retardent polymer.

2.4 Tools

a) It shall be possible to terminate and splice the fiber optical cables with normal tools for terminating optical fibres.

2.5 Fire properties

a) The self-extinguishing cables shall fulfill the requirements in IEC 60332-1.

2.6 Markings

a) The outer sheath of the cable shall have easy readable and durable markings with the following information:

1. manufacturer's name
2. designation
3. F.number
4. accumulative length at every metre of the actual production length (note)
5. preferably also a uniqe production identity
6. year of production

(note) The first and the last length figures shall be readable at/on the production package (drum or other package).

b) € marking is not relevant.

2.7 Quality certificate

a) A quality certificate containing test results or control check points shall accompanying the cable and the invoice. The quality certificate shall indicate the purchase number.

2.8 Documentation, language

a) Product sheets shall be available in Norwegian.

3 ENVIRONMENTAL CONCERNS

a) Temperatures

Storage temperature	-40 °C to +70 °C
Installation temperature	-10 °C to +60 °C
Operating temperature	-40 °C til +60 °C

b) All cables shall be fitted with protective caps at both ends to avoid intrusion of moisture and contamination.

c) Production, use and disposal of the products shall be possible obeying national regulations (Forurensningsloven).
