Treotham Automation has introduced a new range of fibre optic cables
that offer the assurance of continued data communication for 90 minutes in the
event of a fire.
The new HELUCOM FS90 fire safe fibre optic cables are based on the IEC
60331-25 standard, and have been successfully tested for the purpose of
function and data transfer under the influence of flames of 750°C for more than
90 minutes. The maximum damping increase was maintained at E9/125 μm 0.12 dB in
single mode and G50/125 μm 0.27 dB in multimode.
HELUCOM FS90 fire safe fibre optic cables are particularly relevant for tunnels,
underground train tunnels, computer centres, mine sites and all environments where
signal transmission must be ensured in the event of a fire.
HELUCOM FS90 meets the standards for IEC 60332-1 + 60332-3, flame
resistance, IEC 61034 smoke/gas proof, IEC 60754-2 halogen-freedom and
EN50267-2-3 corrosiveness.
Four different cable types are available as
standard inventory: 4 G50/125 μm OM2 (803917), 12 G50/125 μm OM2 (803918), 4
E9/125 μm G652.D (803919) and 12 E9/125 μm G652.D (803920).
