I-V(ZN)H

Description

The I-V(ZN)H Indoor Tight Buffer Cable is engineered for indoor fiber optic installations requiring excellent flexibility, safe flame behavior and reliable mechanical stability. Featuring tight-buffered optical fibers, aramid yarn strength members and a halogen-free LSZH jacket, this cable provides a robust yet installer-friendly solution for structured building networks, FTTB systems and indoor distribution routes.

Its compact size and smooth handling characteristics make it an ideal choice for patching, pigtailing, riser distribution and equipment-room interconnects where clean routing and safe fire performance are essential.

The I-V(ZN)H cable delivers strong optical and mechanical performance tailored for indoor applications:

1. Tight-buffered fibers for easy termination, splicing and connectorization

2. Aramid yarn strength members providing high tensile strength without adding stiffness

3. LSZH  flame-retardant outer jacket, ensuring low smoke and zero halogen emissions

4. Excellent bend performance, especially with G.657.A1/A2 fibers, suited for tight radii in indoor pathways

5. No gel components, enabling clean installation and straightforward fiber preparation

6. Stable attenuation performance across typical indoor temperature ranges

7. Strong crush and pull resistance for rack, cabinet and tray routing environments

These characteristics make the cable well-suited for both backbone fiber distribution inside buildings and short-range patch connections.

Application Scenarios

The I-V(ZN)H Indoor Tight Buffer Cable is used across a wide spectrum of indoor network environments, including:

1. Vertical risers and horizontal distribution pathways

2. Data center racks, cabinets and ODFs

3. Telecommunication rooms and building communication nodes

4. Pigtails, patch cords and equipment jumpers

5. FTTB networks that require safe indoor fiber routing

6. Industrial indoor systems where LSZH compliance is mandatory

7. Short interconnects between equipment, panels and termination boxes

Its flexibility and aramid yarn reinforcement enable smooth installation even in narrow conduits and densely populated cable trays.

Design Advantages

Key design benefits include:

1. Highly flexible construction, ideal for tight bends and cable management

2. Aramid yarn strength system providing stable tensile behavior and durability

3. LSZH jacket with excellent flame performance for safe indoor deployment

4. Easy termination, supporting both field-installable connectors and factory pre-terminated solutions

5. Clean handling, thanks to gel-free tight-buffer design

6. Lightweight and compact form factor simplifying cable routing inside buildings

7. Reliable optical performance for both single-fiber and multi-fiber configurations

These advantages contribute to long-term network reliability and simplified installation workflows.
