Description
The I-V(ZN)H-(BN)H 2×1 Indoor Tight Buffer Cable is engineered for high-performance indoor fiber optic networks requiring excellent flame resistance, mechanical stability and installation flexibility. Designed with a 2×1 duplex geometry, this cable integrates tight-buffered fibers, aramid yarn strength members to deliver reliable performance in structured cabling environments, riser distribution systems and customer-premises connectivity.
Its compact form factor ensures smooth routing along walls, floors and cable trays, while offering superior handling for patching, pigtailing and short equipment interconnects.
Performance Characteristics
The cable combines secure fiber protection with enhanced mechanical behavior suitable for dense indoor wiring:
-
Tight-buffered fibers enabling fast termination and easy connectorization
-
Aramid yarn tensile reinforcement to protect fibers during pulling and installation
-
Arranged in 2×1 form, improving dimensional stability, bend control and crush resistance
-
Halogen-free LSZH jacket meeting fire-safety requirements
-
Excellent bend performance with G.657.A1/A2 fibers for compact routing
-
Gel-free construction allowing clean, simple cable preparation
-
Smooth jacket surface minimizing friction in conduits and trays
-
Consistent attenuation stability across standard indoor temperature ranges
The 2×1 geometry enhances cable management and maintains fiber alignment during installation.
Application Scenarios
The I-V(ZN)H-(BN)H 2×1 cable is ideal for a wide range of indoor fiber networks, including:
-
Building backbone and horizontal distribution within commercial and residential facilities
-
Telecom rooms, data centers and IT cabinets requiring flexible, flame-safe fiber routing
-
Patch cord and pigtail assemblies, thanks to the tight-buffer and duplex geometry
-
FTTB installations, where dual fiber pathways support voice/data or redundant service
-
Rack-to-rack interconnects and ODF termination areas
-
Industrial indoor systems where LSZH performance is mandatory
-
Cable trays, risers and ducts with limited space but high-density demands
Its robust yet flexible construction supports both fixed installation and frequent handling in customer-premises equipment areas.
