ART002_Multi-fibers Indoor Distribution Tight Buffer Fiber Optical Cable

These cables bundle several 900µm tight-buffered fibers within a single jacket. Key structural elements include:

Tight Buffer: A 900µm layer (often LSZH) directly protects the fiber, allowing for direct connectorization without splicing.
Strength Member: Aramid yarn (or fiberglass) provides tensile strength and protects fibers during installation.
Central Strength Member: Some designs (like RFS) use a central FRP rod for added rigidity.
Outer Jacket: Typically LSZH (Low Smoke Zero Halogen) for indoor safety and flame retardance.
Fiber Count: Commonly ranges from 2 to 48 fibers (with 8, 12, and 24 being standard), though some designs support up to 144.

Products Overview

Flame Ratings & Standards

Indoor cables must meet specific fire safety codes depending on the installation space:
LSZH / IEC 60332-3: Standard for many indoor distribution cables, ensuring low smoke and zero halogen.
CPR Euroclass: Ratings like Cca or B2ca indicate reaction to fire performance (B2ca is higher).
Plenum / Riser: In North America, cables are rated for plenum (air handling) or riser (vertical shaft) spaces based on NEC codes.

Key Advantages

Easy Termination: The tight buffer allows field-installable connectors to be directly applied, saving on splicing costs and time.
Flexibility: Suitable for tight spaces and equipment trays within data centers and offices.
Reliability: Eliminating splice points reduces potential failure points and signal loss.
