Fire-Resistant Fiber Optic Cables | B2ca FE180 High-Safety Solutions by ETK Kablo

ETK Kablo’s fire-resistant fiber optic cables ensure continuous data transmission during fire conditions, safeguarding critical communication lines when reliability is most crucial. Certified to B2ca CPR and FE180 fire-resistance standards, these cables maintain optical integrity under extreme heat and flame exposure—ideal for tunnels, hospitals, airports, industrial plants, data centers, and railway networks.

Why Choose Fire-Resistant Fiber Optic Cables

In emergency scenarios, uninterrupted connectivity can save lives and prevent operational collapse. ETK Kablo’s B2ca-classified fiber optic range provides low smoke emission, zero halogen content, and exceptional flame retardance. The design ensures data link continuity even during extended fire exposure, meeting the most demanding construction and safety codes across Europe and the world.

Fire-Resistant Fiber Optic Cable — Frequently Asked Questions

Which fibre is resistant to fire?

The glass optical fibre itself is non-flammable; what determines fire behaviour is the cable construction (insulation, sheath, fillers). For fire-critical areas, choose fire-resistant, LSZH fiber optic cables that are certified (e.g., FE180 and CPR B2ca) to maintain transmission and minimise smoke/toxic gases during a fire.

Which cable is fire resistant?

Fire-resistant cables are specifically designed and tested to keep circuits operating under fire. Look for markings such as FE180, PH90/PH120, or compliance to IEC 60331/EN 50200/BS 6387. In fiber optics, select fire-resistant LSZH designs with CPR B2ca reaction-to-fire class for use in public and safety-critical buildings.

What is the difference between FRLS and LSZH cables?

FRLS = Flame-Retardant, Low Smoke (may still contain halogens).
LSZH = Low Smoke, Zero Halogen (no halogen acids).
Both limit flame spread and smoke, but LSZH additionally avoids corrosive/acidic gases, making it preferred for enclosed, people-dense spaces and sensitive electronics.

What is a fire-resistant cable as per IEC 60331?

A cable that maintains circuit integrity under fire during the IEC 60331 test series (fire with/without shock for a defined duration and temperature). For fiber optics, the relevant part verifies the cable can continue to transmit signals while exposed to flame for the specified time (e.g., FE180 ≈ 180 minutes).

What is a B2ca cable?

B2ca is a CPR reaction-to-fire class (EN 50575) indicating very high performance for building installations: limited heat release and flame spread, with optional sub-classes for smoke (s1a/s1b), droplets (d0/d1), and acidity (a1). A fiber optic cable marked B2ca-s1a,d1,a1 is suitable for stringent safety environments.

What is a fire-rated cable?

“Fire-rated” is a general term for cables certified for fire performance. It can refer to fire-resistant (IEC 60331/EN 50200/BS 6387 – keeps working during fire) or reaction-to-fire (CPR) classes such as B2ca/Cca (limits flame/heat/smoke). In life-safety systems you often need both: fire-resistance for functionality and CPR for building compliance.
