Designed for Scalable Indoor Fiber Infrastructure
Yuhong’s GDX312 cable is tailored for indoor fiber applications that demand high flexibility and core count scalability. With options ranging from 2 to 144 fibers, this model supports the backbone of enterprise, campus, and facility LAN systems where fast internal signal distribution is essential. As a fiber optic cable structured around a loose sheath design, it balances durability and maneuverability—making it suitable for drop ceilings, equipment rooms, and rack interconnects where frequent directional changes or bundling are required.

Stranded Tube Geometry with Central FRP Reinforcement
The cable employs a stranded loose tube construction, with optical fibers organized in color-coded gel-filled tubes, spiraled around a central FRP (fiber-reinforced plastic) rod. This configuration delivers mechanical balance and resistance to compressive stress while maintaining longitudinal flexibility. The gel serves both as a vibration damper and moisture block. In fiber optic internet cable installations across long interior runs, such structure ensures fiber integrity during pulling, routing, or coiling—especially in complex retrofit environments.

Indoor Safety Combined with Protective PE Sheathing
Unlike outdoor cables with thick armoring, the GDX312 is protected by a light yet resilient polyethylene (PE) jacket, suitable for interior settings where reduced smoke and physical protection are key. While not fire-rated for risers or plenums, its outer sheath provides chemical resistance and wear tolerance in technical spaces such as server rooms or clean cable trays. As a cost-effective fiber optic cable for structured indoor layouts, it facilitates high-speed connectivity with minimal signal attenuation.

 

Product Advantages

Loose Sheath Layout Enables Easy Multi-Core Handling
The GDX312’s stranded loose tube layout allows clear fiber separation, improving manageability during fusion splicing, fan-out processing, or connectorization. Installers can access individual fiber bundles without disrupting neighboring cores—a vital feature in multi-core fiber optic cable applications where changes or expansions are expected. This design also reduces the risk of stress concentration, enabling more consistent optical transmission over extended deployment lifecycles.

Non-Metallic Central Strength Without Grounding Requirements
The use of an FRP central rod removes the need for metallic strength members, reducing cable weight and simplifying installation through EMI-sensitive zones like data centers or control rooms. This non-metallic composition also means no grounding is required, streamlining routing through patch panels and MUX systems. For fiber optic cable manufacturers, this structural approach supports compliance with low-interference system architecture and simplifies integration across modern ICT facilities.

Cost-Efficient Core Density for Large Indoor Networks
With fiber counts up to 144 cores in a single sheath, GDX312 delivers dense connectivity without requiring large conduits or multiple parallel runs. This reduces material use and installation labor, particularly in enterprise buildings with centralized distribution points. It enables fiber optic cable suppliers to support high-bandwidth clients such as campuses or research centers with a single inventory line, minimizing SKU proliferation while supporting tailored lengths and terminations.

 

Use Scenarios

Structured Cabling in Government Office Buildings
In public-sector buildings where data security and signal integrity are paramount, infrastructure contractors often select non-metallic indoor fiber optic internet cable solutions. GDX312 enables high-fiber-count distribution from secure mainframes to departmental switch cabinets without risk of EMI interference. The stranded design simplifies route changes during office reconfiguration, while the PE jacket ensures clean, abrasion-resistant routing in false ceilings and secure floor ducts.

LAN Backbones in Educational Institutions
IT teams managing digital infrastructure for schools and universities require robust, scalable cables that support large-volume traffic between computer labs, server rooms, and classroom blocks. GDX312’s loose sheath construction allows installers to branch out sub-networks from a central backbone without disturbing existing links. Its fiber optic cable configuration maintains performance over long, continuous runs within walls or cable trays across multi-level academic facilities.

Enterprise Data System Builds by Low Voltage Integrators
For system integrators working on enterprise office spaces, cloud hosting sites, or BPO centers, high-density indoor cabling is critical. GDX312 provides up to 144 fibers in a flexible format, which can be routed between data closets, IDFs, and MMRs without excessive bulk. The non-metallic core simplifies installation near power sources and ensures compatibility with cable management hardware used in high-speed fiber optic internet cable networks.

FAQ

Can the GDX312 be used in riser or plenum spaces?
While it has a PE outer sheath suitable for general indoor use, GDX312 is not fire-rated for riser or plenum installations. It is best applied in standard interior environments such as offices, cable trays, and utility rooms.

Is this cable compatible with common fusion splicing methods?
Yes, the loose tube design with color-coded fibers allows for easy stripping and alignment during fusion splicing. It is compatible with standard splicing sleeves and trays used in indoor telecom and enterprise setups.

What are the length options available for custom orders?
Yuhong supports flexible length configurations based on your layout needs, from small-scale patching applications to long-run backbone deployments. Custom lengths help minimize waste and installation time.

Does the cable require grounding during installation?
No. The cable contains no metallic components. Its central strength member is made of FRP, allowing it to be installed without grounding or additional bonding hardware—ideal for EMI-sensitive environments.

Can the GDX312 be pre-terminated before delivery?
Pre-termination options are available upon request. This helps reduce on-site labor by allowing rapid deployment with factory-installed connectors, particularly useful in modular network rollouts or tight project timelines.
