Hone OFNR (Optical Fiber Nonconductive Riser) Fiber Optic Cable
Hone’s OFNR (Optical Fiber Nonconductive Riser) cable is an indoor fiber optic cable designed for distribution between building floors. Its non-conductive nature helps prevent fire spread between riser areas.
Description
OFNR (Optical Fiber Nonconductive Riser) cable is specifically designed for indoor riser applications. It contains no electrically conductive components, making it suitable for vertical installations within buildings. Both the sub-cable and outer jacket are constructed from LSZH (low-smoke, zero-halogen) material, which is crucial for preventing fire propagation from floor to floor.
Application
This cable is ideal for:
- Indoor building riser cable applications
Features
- Two parallel FRP (Fiber Reinforced Plastic) strength members enhance crush resistance.
- Non-conductive cable materials are suitable for riser areas.
- LSZH subunit sheath and outer jacket are flame retardant.
- Environmentally friendly materials are used for indoor applications.
- Loose tube fiber units facilitate easy operation for distribution and construction.
