Custom 4-144 Core Indoor Distribution Fiber Cable | WolonFiber

Product Description

Indoor Distribution Fiber Optic Cable acts as the central nervous system for intra-building telecommunications. Unlike outdoor loose-tube cables that require complex breakout kits, this distribution cable encases each individual glass strand in a 900μm protective buffer. WolonFiber extrudes these multi-core cables directly from our Huangshi and Wuhan production lines. By controlling the entire manufacturing process with our 400-employee workforce, we ensure precise stranding pitches and consistent aramid yarn distribution. This guarantees that whether you are pulling a 4-core line through a ceiling plenum or hauling a heavy 144-core trunk up a vertical elevator shaft, the delicate silica cores remain protected against elongation.

Product Highlights

• Scalable Core Density: Manufactured in highly scalable configurations ranging from low-density 4-fiber conduits up to massive 144-fiber trunk backbones.

• Direct Termination Architecture: Houses 900μm tight-buffered fibers, granting technicians the physical rigidity required to epoxy or crimp connectors directly without utilizing fusion splice trays.

• Sub-Unit Grouping: Core counts exceeding 12 fibers are intelligently bundled into color-coded sub-units (e.g., twelve 12-fiber sub-jackets for a 144-core cable) to simplify rack-level routing.

• Vertical Integration Rated: Extruded with strictly certified OFNR (Riser), OFNP (Plenum), or LSZH (Low Smoke Zero Halogen) jacketing to comply with rigorous indoor fire codes.

Application Scenarios

• Vertical riser backbones connecting the Main Distribution Frame (MDF) to floor-level Intermediate Distribution Frames (IDF).

• High-capacity, direct-terminated patching within enterprise data center ODFs (Optical Distribution Frames).

Technical Specifications

Engineering FAQs

• Q: How exactly is the 144-core variant structured internally? A: To maintain flexibility and organization, a 144-core distribution cable utilizes a sub-unit architecture. It typically contains 12 individual sub-jackets. Each sub-jacket contains 12 color-coded 900μm tight-buffered fibers and its own aramid yarn, all wrapped within the master outer jacket.

• Q: Can I use this distribution cable outdoors between buildings? A: No. This cable is strictly designed for dry, indoor environments. It lacks water-blocking gel (or swelling tape) and the UV-resistant PE jacket required to survive underground conduit flooding or prolonged sun exposure.

• Q: Why choose tight-buffered distribution cable over loose-tube? A: The 900μm tight buffer adheres directly to the fiber coating. This provides enough physical stability to terminate an LC or SC connector directly onto the fiber end. Loose tube cables (250μm) are too fragile for direct connectorization and strictly require pigtail fusion splicing.

• Q: Does WolonFiber support custom sub-unit printing? A: Yes. For high-core-count cables, we can laser-print specific alphanumeric identifiers (e.g., "Sub-Unit 1", "Sub-Unit 2") directly onto the sub-jackets during extrusion to accelerate your field technicians' sorting process.
