II: SPECIFICATIONS FOR FIBER OPTIC NETWORK
AND CABLES
Article II.1: Fiber Optic specifications
The following features should be taken into consideration while choosing fibre optic and
cable :
All fibre optics must meet the requirements of ITU-T Recommendations;
Each cable must have traceability of the fibre optic back to the original fibre ID
number and test parameters as provided by the fibre manufacturer ;
Each fibre must be distinguishable from other fibres in the same duct by means of
colour coding ink visible throughout the design life of the cable (as Defined by TIA5987C);
Fibre optics shall have a high level of splice compatibility with fibre optics from other
manufacturers;
Performance specifications for standard single mode Fibre optic (ITU-T G.652) and
recommended multimode Fibre optics (ITU-T G.651) are detailed in Appendix3 and 4.
II.2 : Cable Specifications
The cables must be circular in cross section and free from pinholes, joints, repairs and other
defects.
Materials used in the construction of the cable shall not affect the physical or optical
properties of the fibres and shall be compatible with each other.
The above mentioned provisions (section 2.1 and 2.2) comprise requirements for the mostly
used materials for FOC network and its specifications. However, it remains the network
provider responsibility to identify and procure all the required materials for the complete
FOC installation work
