Acceleration [N] = [Kg] x 9.81[m/sec 2 ] Reference: 1 pound = 4.45N
Tensile Strength (IEC 60794-1-2-E1) FO cable is pulled by a tensile
force measured in Newton Ex: 2700 N Crush Resistance (IEC
60794-1-2-E3) FO Cable is tested using a plate which applies a
crushing load measured in Newton Ex: 3000 N/10cm (linear) Bending
Radius (IEC 60794-1-2-E11 A) FO Cable is bent to meet its specified
bending radius Ex: Generally, 15xOD during installation and 10x OD
during operation OD = outer diameter of cable, non-armoured cable
Requirement: Mechanical Tests are conducted for 1 minute or more No
fibre break or Attenuation more than 0.05 db Mechanical

Optical FibreNetwork IQ Training Manual23 Water Penetration
(IEC 60794-1-2-F5) FO cable prevents water from penetrating inside
the cable and inside the loose tubes Temperature Cycle (IEC
60794-1-2-F1) FO Cable can be exposed to low temperature or high
temperature without any material deformation or high attenuation
more than 0.05 db Ex: -40C to +70C Environmental Characteristics of
FO Cable 3 meter sample Water height 1 meter 24 hours No water
penetrate to the sealed side of the cable Requirement: Heat Chamber
-40C to +70C Dwell time 6 hour Measurement at 1310 nm & 1550 nm
Max Att. 0.1 db/km

Optical FibreNetwork IQ Training Manual24 Cable Summary Two
main design options for fibre cables: Loose Tube (250um coated
fibres) Tight Buffered (900um coated fibres) Loose Tube typically
outdoor application Loose tube isolates fibre from external strain
250um easy to splice Use fan out tube if direct termination with
connectors Tight buffered cables typically indoor application 900um
allows direct termination with connectors Telcordia colour scheme
is standard Corning code; others available
