Description
Riser Cables are indoor fiber optic cables designed for vertical distribution between floors in multi-story buildings. Installed in designated riser shafts, elevator pathways or structured building conduits, these cables must meet strict flame-retardant and smoke-control requirements to prevent fire propagation between floors. Our riser-rated fiber optic cables provide a safe, durable and high-performance solution for FTTB, enterprise networks, data centers and commercial building communication systems.
Manufactured using tight-buffer fiber units, aramid yarn reinforcement and fire-resistant riser jacket compounds, these cables serve as the core transmission layer for system integrators and installers building secure and efficient indoor optical networks.
Performance Characteristics
Our riser cables are engineered to balance mechanical strength, optical stability and vertical fire-safety requirements:
-
Tight-buffered fibers for easy stripping, termination and splicing
-
Aramid yarn strength members ensuring tensile protection during installation
-
Flame-retardant jackets designed to limit flame spread in vertical shafts
-
Low smoke generation suitable for indoor communication rooms
-
High bend-performance fibers (G.657.A1/A2) ideal for compact routing within riser ducts
-
Gel-free construction for clean preparation during splicing
-
Stable attenuation across typical indoor temperature ranges
These characteristics allow installers and equipment manufacturers to build dependable vertical distribution networks inside commercial and residential buildings.
Application Scenarios
Riser cables form the backbone of indoor optical distribution in multi-floor structures. They are used by integrators and cable assembly companies to create:
-
Vertical backbone routes between building floors
-
Inter-floor links in commercial buildings, offices and data centers
-
FTTB riser pathways connecting distribution frames to user floors
-
Backbone sections feeding horizontal distribution networks
-
Indoor telecom rooms and communication shafts requiring flame-safe cable structures
Their riser-rated jacket ensures compliance with building codes for vertical installations where fire containment is critical.
