Oil based on right silicone oil or artificial oil, wherein, natural silicone molecule amount is larger, and performance is good；Artificial oil is by increasing strand
In ehter bond quantity reach the performance of low-temperature low-viscosity.Base oil molecules amount is big, and intrinsic viscosity is higher, with the reduction of temperature,
Viscosity can increase, and flexibility reduces.And the phase same sex of above-mentioned base oil and sleeve pipe is poor, therefore, adds lubricant and keep big
The flexibility of molecular chain-end, the viscosity of lotion when improving low temperature.Lubricant can use small molecule silicone oil, compatible with base oil
Property is good.When further, in order to avoid low temperature environment, water condensation causes to damage optical fiber 120, and a certain amount of water removal is added in lotion
Agent, keep the water content of lotion.In the present embodiment, the water content of low temperature resistant fine cream 130 is less than 2%.
In the present embodiment, by mass percentage, raw material includes natural silicone oil or artificial oil 70~85%, lubricant 10
~15%, deicer 5~15%.The resistance to low temperature of low temperature resistant fine cream 130 is preferable as made from the proportioning, at -65~-50 DEG C
Under conditions of lotion keep soft.
In the present embodiment, optical fiber 120 is dispersive optical fiber, and the core number of optical fiber 120 is 2~24 cores.By above-mentioned optical fiber 120
The transmission performance of the Loose tube 100 of formation is stable, meets actual demand.The body 110 of Loose tube 100 is by poly terephthalic acid fourth
Diol ester (PET) is made, and PET light weights are nontoxic, and heat-resisting ageing-resisting performance is good, and electrical insulation capability is good, is affected by temperature
It is small.PET allows Loose tube 100 to be applied in temperature is compared with low environment, expands the use range of Loose tube 100.
