Latest company news about Why does France Telecom require telephone cable to use LSZH?

France Telecom's requirement for low-smoke halogen-free sheaths on telephone lines is primarily aimed at significantly improving fire safety in densely populated areas, protecting lives and critical equipment. This is based on the following key reasons:

Safety First: Low-smoke halogen-free materials produce less smoke and do not release toxic hydrogen halides when burning, maintaining visibility in a fire, preventing secondary corrosion, and buying time for evacuation and rescue.

Regulatory and Standards-Driven: Compliance with mandatory standards such as the EU CPR is a prerequisite for fire safety inspections.

Protecting Critical Infrastructure: In locations such as data centers and subway stations, it prevents communication interruptions and ensures business continuity.

Long-Term Cost-Effectiveness: Although the initial cost is higher, its flame-retardant and aging-resistant properties reduce fire risk and maintenance costs.

This reflects France Telecom's necessary choice to fulfill its safety responsibilities, meet regulations, and ensure service quality.
