Optical Cable Full-section Water-blocking Technology Principle

*Full-section water-blocking:

Full-section water-blocking design is essential for outdoor long-term buried optical cables. The system consists of fiber paste, cable paste, water-blocking yarn and expandable water-blocking tape.

*operating principle:

When water invades cable cracks, water-blocking materials expand rapidly to solidify water flow and block diffusion path. Fiber paste also lubricates bare fibers and buffers micro-bending stress.

*Advantages:

Partial water-blocking only protects fiber tubes, while full-section structure stops water spreading along cable longitudinal direction. It prolongs cable service life to 25 years, adapting humid underground, rainy outdoor overhead harsh working environments.

Extrusion mold precision machining is pre-process supporting work for loose tube and sheath extrusion production. Mold inner hole dimension directly decides inner and outer diameter tolerance of extruded plastic parts. High-hardness alloy steel is adopted as mold raw material, processed by five-axis CNC lathe for mirror inner hole polishing. Technicians design gradient flow channel inside molds to ensure uniform plastic melting flow without material stagnation. Different aperture molds are classified for producing micro tubes, standard loose tubes and thick outer sheaths. Regular mold grinding maintenance is required to avoid burr scratch on cable inner wall. High-precision mold machining is the premise for standardized dimension of mass-produced optical cable accessories.

Qualified optical cable design life is 25 years, and failure derives from natural aging and external damage. Natural aging includes sheath polymer ultraviolet degradation, internal water-blocking material failure, fiber coating gradual oxidation leading to micro-bending attenuation rise. External damage covers construction mechanical cutting, rodent gnawing, geological displacement squeezing, artificial road construction excavation. Regular online OTDR detection can locate hidden fault points. Daily route protection, marking pile layout and regular patrolling can effectively delay cable aging damage and extend actual service life of communication optical line infrastructure.

Outer sheath extrusion is the final cladding molding process for finished optical cable in whole production flow. According to customer demand, factories select PE, LSZH, MDPE modified plastic particles for sheath processing. Plastic particles are dehumidified and mixed with anti-ultraviolet, anti-aging functional masterbatch in advance. The extruder melts plastic materials and coats the outer surface of armored or non-armored cable core integrally. Online diameter detector monitors sheath thickness and roundness in real time to avoid uneven wall thickness. Multi-stage water cooling tank shapes outer sheath gradually to prevent thermal shrinkage cracking. Printed inkjet coding marks cable model, production batch and standard length on sheath surface synchronously during extrusion.

Photonic crystal fiber is new-generation microstructure special optical fiber different from traditional solid core fiber, designed with periodic micro pore array structure. It controls optical transmission path via photonic bandgap effect, breaking the transmission limit of traditional fiber. It has ultra-bend resistance, anti-high-power laser and adjustable nonlinear optical characteristics. It is not limited to communication transmission, widely applied in high-precision medical laser equipment, industrial laser cutting, aerospace optical sensing and quantum communication fields. Customized pore structure can adjust fiber transmission wavelength freely. In the next decade, photonic crystal fiber will be popularized in ultra-high-speed quantum communication and industrial optical control fields, expanding new application boundary of optical fiber technology beyond civilian network communication.
