Indoor optical fiber cable is a highly flexible, non-metallic, tight-buffered bundled optical cable primarily used for indoor backbone cabling, building vertical cabling, equipment room connections, and high-density cabling environments. Its characteristics include strong bending resistance, flame retardancy, and environmental friendliness (low smoke, halogen-free). It is categorized based on fiber core count, fiber mode (single-mode/multimode), and sheath material.
1. Application Scenarios of Indoor Optical Fiber Cable
Due to its excellent flexibility and non-metallic structure, GJFJH is ideal for indoor environments with stringent space requirements for cabling:
- Building Vertical and Horizontal Cabling: Suitable for backbone and horizontal cabling within buildings, especially in low-voltage shafts and suspended ceilings.
- Data Centers and Server Rooms: Commonly used for fiber optic connections, patch cords, and high-density patch panels between equipment in data centers and server rooms.
- Office and Home Cabling: Suitable for cabling in office cubicles and for laying 10 Gigabit networks within homes or businesses.
- Special Environments: Due to its non-metallic composition, it is suitable for locations with electromagnetic interference or where high fire resistance and flame retardancy requirements are necessary.
2. Types of GJFJH Indoor Optical Cables
The naming convention of GJFJH reflects its structural characteristics (G-optical cable, J-indoor, F-non-metallic reinforcement, J-tight-buffered fiber, H-bundle/subunit):
- By fiber core count:
Single-core/Dual-core: Typically used for pigtails or indoor patch cords.
Multi-core bundled (4-core, 6-core, 8-core, 12-24-core)
- By fiber mode:
Single-mode (G.652, G.657): Used for long-distance transmission, such as external backbone access to buildings.
Multi-mode (OM1, OM2, OM3, OM4): Used for high-bandwidth, short-distance transmission, such as internal interconnection within data centers.
- By sheath material:
PVC/Flame-retardant PVC: Commonly used general-purpose type.
Low-smoke halogen-free flame-retardant (LSZH): Used in environments with high environmental and fire safety requirements (such as hospitals, subways, densely populated areas).
GJFJH fiber optic cables, with their single tight-buffered fiber structure, are easy to strip and connect directly to connectors, making them a commonly used high-speed fiber optic cable in indoor structured cabling.
The indoor optical cable market has broad prospects, benefiting from the construction of 5G base stations, the promotion of gigabit optical networks (FTTH/FTTR), and the rapid development of data centers, leading to continuous growth in demand. With increasing demands for computing power networks, indoor optical cables are evolving towards higher bandwidth, lower loss, greater bending resistance, and greener designs, playing a crucial role, especially in data centers and high-quality home network coverage.
