Plenum Cable

Description

Plenum Cables are high-safety indoor fiber optic cables engineered for installation in building air-handling spaces such as ceilings, raised floors, airflow plenums and return air ducts. These zones require materials that limit flame spread and smoke generation under fire conditions. Our plenum-rated fiber optic cables are designed with specialized flame-retardant, low-smoke materials that comply with stringent building codes and ensure the safe operation of telecommunication networks in critical indoor pathways.

Produced with tight-buffer fiber structures and high-performance compound jackets, our plenum cables serve as the cable substrate used by system integrators, installers and assembly houses to create reliable indoor optical connections — including use in risers, backbone links, inter-floor routing and termination inside ODFs or equipment rooms.

Performance Characteristics

Our plenum-rated cables are engineered to balance optical performance, mechanical strength and strict fire-safety requirements:

1. Tight-buffered fibers, optimized for clean handling and easy connectorization

2. Aramid yarn strength members, offering mechanical support without compromising flexibility

3. High-performance plenum jackets formulated to minimize flame propagation

4. Extremely low smoke emission, compliant with air-handling space safety standards

5. Bend-insensitive fiber options (G.657.A1/A2) for tight pathways and compact routing

6. Gel-free construction, making fiber preparation simple and clean

7. Stable attenuation performance across typical indoor temperature and humidity ranges

These features ensure that the cable substrate performs reliably during installation and long-term operation, even in demanding building environments.

Application Scenarios

Our plenum cables are used by system integrators and installers as the base cable for:

1. Indoor backbone and horizontal distribution inside commercial buildings

2. Routing in plenum spaces, such as return air ceilings and raised floors

3. Telecommunications equipment rooms and structured wiring closets

4. Data center interconnect pathways with strict fire-safety compliance

5. FTTB/FTTO network environments requiring safe indoor optical infrastructure

Design Advantages

Plenum cables manufactured by us offer several advantages for both integration and installation:

1. High flame resistance and low smoke toxicity, meeting the most demanding indoor safety standards

2. Superior handling characteristics, supporting efficient stripping, splicing and termination

3. Consistent mechanical behavior, vital for mass connectorization processes

4. Lightweight and flexible, simplifying routing through dense plenum pathways

5. Compatible with standard connectors once assembled by third-party pigtail and patch-cord manufacturers

6. Excellent fire code compliance, enabling deployment in critical building areas

These qualities ensure dependable safety, easy use in assembly workflows and long-term performance in indoor optical networks.
