IP67 Pole Mount 48 Cores Fiber Optic Splice Closure Outdoor Dome Fiber Optic Joint Closure

The KCO-DM22-48LX is a compact dome-type fiber optic splice closure designed for outdoor deployment. It features four cable ports — two for input and two for output — and supports a maximum capacity of 48 fibers. The enclosure accommodates up to four splice trays, each holding 12 fibers.

Built for pole, wall, or strand mounting, the rugged housing delivers fire resistance, anti-aging, waterproof, anti-UV, and quakeproof protection, safeguarding splices against pulling, twisting, and impact. It ensures long-term reliability across ambient temperatures from -40℃ to +65℃.

The closure is suitable for direct connection or splicing of optical fibers in aerial, underground, direct-buried, wall-mounting, hand-hole, and duct applications.

• Stretch: After sealing and inflating to 60 kPa ± 5 kPa, the body withstands 1000 N axial tension for 1 minute with no change in air pressure.
• Flattening: After sealing and inflating to 60 kPa ± 5 kPa, the body bears a horizontal uniform pressure of 2000 N/10 cm; the pipe withstands 600 N/10 cm with no change in air pressure.
• Impact: After sealing and inflating to 60 kPa ± 5 kPa, a 1 kg steel ball is dropped from 1.6 m onto the box three times; the box does not crack and pressure remains unchanged.
• Voltage Resistance: At 1.5 m water depth after 24-hour soak, withstands 15 kV DC for 1 minute without breakdown or arcing.
• High-Temperature Test: After sealing and inflating to 60 kPa ± 5 kPa, at +60℃ for 2 hours, the box shows no deformation or leakage.
• Low-Temperature Test: After sealing and inflating to 60 kPa ± 5 kPa, at -40℃ for 2 hours, the box shows no deformation or leakage.
• Temperature Cycle Test: After sealing and inflating to 60 kPa ± 5 kPa, three cycles at -40℃ with 2-hour constant temperature at each point; pressure drop amplitude ≤ 5 kPa.
• Bending: After sealing and inflating to 60 kPa ± 5 kPa, with 150 N tension load and ±45° bending angle over 10 cycles, no change in air pressure.
• Torsion: After sealing and inflating to 60 kPa ± 5 kPa, with 50 N·m torque and +90° torsion angle over 10 cycles, no change in air pressure.
• Sealing Performance: At 100 kPa ± 5 kPa gas pressure, water-bath soak for 15 minutes shows no bubble escape; no change after 24 hours under pressure.
• Insulation Resistance: At 1.5 m water depth after 24-hour soak, insulation resistance ≥ 2 × 10⁴ MΩ.
