Fibre Optic Cable
Fibre Optic Cable
(OP)
I am looking for a temperature range specification for fibre optic cable. I wish to use fibre optics in a -50C environment. I am concerned that this low temperature will effect signal propagation in the core. Will the fibre become brittle and cracks form? As for the rest of the equipment, it will be in temperature regulated cabinets.
Does anyone have any expertise in this area? Your advice would be appreciated.
Thanks,

ALTOS Low Temperature Cable with an Operational temperature range of -55C to 70C (-67 to 158F).
There is no mention of an installation temperature, but I will make the client aware of the concerns "bridog" brought up about a higher (negatively speaking)installation temperature.
One issue with this type of cable, it is a speciality order, so the order will need to meet a minimal quantity (length) requirements. This will not be a concern in this case, but is still something to think about.
Thanks again,

WEll, the fibre can be used at that low temperature..
but you will have to use that fibre which have a very strong cladding and and strong outer core...
you can use W profile dispersion shifted fibre..
and the refractive index of the clad should be much lower than that of the core...
and offcourse use the glass fibre, not the plastic glass fibre.. :)
