Looking for a reliable and high-performance fiber optic cable for your indoor network infrastructure? Our Indoor Tight Buffer Fiber Cable offers an ideal solution for data centers, enterprise networks, and vertical floor-to-floor trunking in commercial buildings. Featuring tight buffer construction, plenum-rated (OFNP) flame retardant PVC jacket, and Corning® single-mode fibers, this cable ensures both compliance and performance in critical environments.
Whether you’re installing in riser shafts or horizontal cable trays, this fiber cable delivers secure transmission, robust mechanical strength, and clean, professional results. As a trusted fiber optic cable supplier, we offer flexible configurations from 2 to 24 cores, ready for both standard and customized indoor deployments.
Overview of Our Indoor Tight Buffer Fiber Cable
Our Indoor Tight Buffer Fiber Cable is designed for high-density, high-performance environments where safety and signal integrity are essential. It features:
- 2 to 24 colored 900μm tight-buffered fibers
- Aramid yarn as a strength member for tensile durability
- A flame-retardant, plenum-rated (OFNP) outer jacket
- UL Listed and fully compliant with EU RoHS and REACH directives
The cable is available in 12 TIA/EIA standard color-coded fibers or custom color configurations upon request. Standard print on the jacket includes key product identifiers such as fiber type, NEC fire rating, and running length markers, which help installers with traceability and accuracy.
Key Features of Our Indoor Tight Buffer Fiber Cable
- Tight Buffer Construction: Each fiber is individually buffered to 900μm, simplifying termination and connectorization.
- Fire-Rated Plenum Jacket (OFNP): Meets the strictest fire safety codes for indoor installations, particularly in plenum spaces.
- Corning® Optical Fiber: Renowned for low attenuation and high performance, perfect for long-distance single-mode transmission.
- Durable Outer Jacket: Offers protection during pulling, installation, and operation in rugged indoor settings.
- Consistent Buffer Strip Force: Maintains between 3.5–5 lbs/ft, allowing easier and more predictable onsite termination.
- Full RoHS and REACH Compliance: Meets environmental and safety standards for global installations.
Applications of Indoor Tight Buffer Fiber Cable
This Indoor Tight Buffer Fiber Cable is engineered for use in a wide range of environments including:
- Indoor backbone/trunking applications
- Vertical riser shafts (floor-to-floor)
- Data centers and server rooms
- Enterprise LAN environments
- Central offices or telecom rooms
- Educational, healthcare, or commercial buildings
Its flexibility and performance make it ideal for FTTH (Fiber to the Home), FTTB (Fiber to the Building), and FTTP (Fiber to the Premises) implementations when safety and plenum ratings are critical.
Temperature Ratings
- Operating Temperature:
- 2–24 Cores: 0°C to +70°C
- 48–72 Cores: -40°C to +70°C
- Storage Temperature: -40°C to +70°C
These wide temperature tolerances ensure that the cable remains stable and functional in varying indoor conditions, from cold equipment rooms to warmer cable risers.
