The structure designing and manufacturing technique of halogen-free flame-retardant optical cables were described in detail in this papers

and the investigation on the properties especially the burning behaviour of above-named cable were carried out. The results demonstrated that the cable has the same transmission properties as the traditional cable and it is characterized by its small smoke

non-toxicity and no flame spread during fire. It is a novel non-pollutant optical cable which can be used in local networks and specific networks with fire prevention requirements.
