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:
-
Tight-buffered fibers, optimized for clean handling and easy connectorization
-
Aramid yarn strength members, offering mechanical support without compromising flexibility
-
High-performance plenum jackets formulated to minimize flame propagation
-
Extremely low smoke emission, compliant with air-handling space safety standards
-
Bend-insensitive fiber options (G.657.A1/A2) for tight pathways and compact routing
-
Gel-free construction, making fiber preparation simple and clean
-
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:
-
Indoor backbone and horizontal distribution inside commercial buildings
-
Routing in plenum spaces, such as return air ceilings and raised floors
-
Telecommunications equipment rooms and structured wiring closets
-
Data center interconnect pathways with strict fire-safety compliance
-
FTTB/FTTO network environments requiring safe indoor optical infrastructure
Design Advantages
Plenum cables manufactured by us offer several advantages for both integration and installation:
-
High flame resistance and low smoke toxicity, meeting the most demanding indoor safety standards
-
Superior handling characteristics, supporting efficient stripping, splicing and termination
-
Consistent mechanical behavior, vital for mass connectorization processes
-
Lightweight and flexible, simplifying routing through dense plenum pathways
-
Compatible with standard connectors once assembled by third-party pigtail and patch-cord manufacturers
-
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.
