Fiber Optic Splice Closure

Fiber Optic Splice Closure The GTJA208-9 Closure allows two cables in and three cables out (with three stand-alone Cable Entry Ports and one oval cable entry port). It accommodates the splicing and branching of the cable which is used in aerial-hanger, wall-mounting or direct buried. The Closure is an openable box which is made from high-quality PC. The closure and the foundation plate are sealed with Silicon Gum Material which fixes tightly by hoop. And the entry ports are sealed by heat-shrinkable tube. The Closure can be opened and used again. Closure Specification Dimension (mm): Φ100×340, Weight (Kg): 1.5, Cable Diameter (mm): Φ7-Φ18, Cables Entry & Exit: 2 & 3, Max Capacity of Cores Per Splice Tray 12 ( Single ), Max Capacity of Splice Trays/ Closure 2, Max Capacity of Core 24 ( Single ), Sealing Structure of Cable Entry Port Heat-shrinkable Sealing Structure, Sealing Structure Silicon Gum Material. Accessories Splice Protective Tube(Splicing Sleeves):24pcs (P/N: FPS-01) Hanging Hook: 1Set (Aerial-hanging or Wall-mounting) Cables Ties: 8pcs(3x100mm) Heat-shringkable Tube: Φ50x150mm 1pc,Φ28x150mm 3pcs Branch Block: 1pc Marking Note: 4x24pcs Technical Specification Item Technical Specification AppearanceIntact in shape, no burrs, bubbles, chaps, pores, warps, impurities and other defects, all background colors should be even and continual. Electrical jointing deviceInside Optic Fiber Closures: metallic components of fiber cables has the functions of electrical putting through, earthing connection and disconnecting. It is possible to install earthing deriving device outside the housing Sealing performanceAfter sealing according to the stipulated operation procedures, the injected air pressure is 100KPa±5Kpa, when immersed in clean water of normal temperature for 15 minutes, there should be no air bubbles, then observed for 24 hours, there should be no change of air pressure. Re-sealing performanceAfter reopening and resealing according to the stipulated operation procedures, the injected air pressure is 100KPa±5Kpa, when immersed in clean water of normal temperature for 15 minutes, there should be no air bubbles, then observed for 24 hours, there should be no change of air pressure. PullBearing pull is 800N at axle orientation, there should be no breakage on the housing. PunchingBearing pressure of 2000N/10cm for 1 minutes, there should be no breakage on the housing ImpactBearing impact energy of 16Nm, 3 times of impacts there should be not breakage on the housing Bending The spot between the Optic Fiber Closures and seal fitting can bear bending tension of 150N at bending angle of ±450 for 10 circles, there should be no breakage on the housing TorsionBearing torsion 50Nm, 10 circle at torsion angle±900, There should be no breakage on the housing. Temperature circleInjected air pressure of 60KPa±5 KPa, the temperature circle ranging from -40 +65, 10 times of the circular tests (one circular consists of high temperature for 2 hours + indoor temperature for 2 hours + low temperature for 2 hours + indoor temperature for 2 hours ) when the pressure declines, the amplitude is 5Kpa, immerse the swatch in clean water of normal temperature for 15 minutes, there should be no air bubbles. Voltage resistance strengthAfter sealing the Optic Fiber Closures according to the stipulated operation procedures, immerse it in clean water of normal temperature in 1.5m depth for 24 hours, there should be no breakdown or arc over between the metallic components of the Optic Fiber Closures, between metallic components and the ground at DC 15KV for 1 minutes. Isolating resistanceAfter sealing the Optic Fiber Closures according to stipulated operation procedure, immerse it in clean water in 1.5m depth for 24h, the isolating resistance between the metallic components of the Optic Fiber Closures, between the metallic components and the ground should be 2×104MΩ.
