4 Cable Ports 256 Cores IP67 Waterproof Fiber Optic Splice Closure Fiber Optic Joint Closure

The KCO-GJS04256 is a universal access junction box designed for the continuity and segregation of medium-capacity optical cables in optical power and transport network deployments. Its design ensures mechanical continuity of cable tensile elements while protecting fibers, splices, and optical devices, facilitating organized splice management and excess fiber storage.

• FTTx networks (FTTA, FTTB, FTTH, FTTO)
• Telecommunications infrastructure
• Internet service provider networks
• Data centers
• CATV systems

• Advanced internal structure design prevents fiber attenuation
• Spacious interior for winding and storing fibers
• Flip-style fiber splice trays for easy access
• Curved radius meets international standards
• Quick and easy addition or removal of splice trays
• Innovative elastic integrated seal fitting
• PC material for plastic parts; excellent steel for external fasteners and structural components
• Reusable design with capacity expansion capability for multiple deployments
• Supports electrical connection and disconnection for fiber optic cables

• Four independent cable accesses at one end, each allowing individualized entry of at least two medium-capacity multifiber cables (double inputs) and up to six small-capacity optical cables (7 mm).
• Closing lid is fully assembled and removable without special tools, thanks to the clip-type hermetic seal.
• Cable access sealing uses rubber gaskets with pre-cut entries.
• Input/output cable diameter range: 22 mm to 7 mm. Maximum 256 fiber fusions (double layer).
• Rectangular, wide-reach, easy-access splice trays with extendable tabs for better fiber storage up to 32 fibers (double layer). Both the support block and individual trays rotate to 90° and interlock in fixed positions to facilitate installation.
• Boxes can be opened, closed, and manipulated without interrupting circuits in operation, allowing cable joining and segregation without cutting all fibers, as well as adequate storage of leftover tubes and fibers.
• Axial tension load per cable: > D/45 mm × 1000 N (D = cable diameter), 1 hour per cable. Cable displacement < 3 mm.
• Flexion per cable: 30° maximum at 500 N. Force applied 400 mm from seal end. 5 cycles per cable.
• Cable torque: maximum 90° at 50 N. Force applied 400 mm from seal end. 5 cycles per cable.
• Vibration resistance: 10 to 15 Hz, one octave per minute, sinusoidal cycle, 3 mm amplitude (6 mm crest to crest). Cable fastened 500 mm from seal end. Duration: 2 hours per axis.
• Static load: > 1000 N (25 cm², 10 min).
• Operating temperature: −25°C to +70°C.
• Mechanical impact protection: IK09 (20 J).
• Once closed, the box is completely hermetic and resistant to outdoor conditions. Protection degree: IP-68.
• Materials designed for a minimum service life of 20 years.
