MT-1552 China 48 core closure 96 core closure dome mechanical seal fiber optic splice closure
Dome Fiber Optic Splice Closure is used in aerial, wall-mounting applications, for the straight-through and branching splice of the fiber cable. The device allows for direct jointing and bifurcated jointing. It also protects fiber optic splices from the elements while providing fast and easy no-cost re-entry.
Screw sealing type
Heat shrink type
Seal performance: after the box is sealed, inflate to 100kPa inwards (inflation only apply to the models with the air hole), and then soak it in the water of normal temperature, after 15 minutes of steady observation, there is no bubble to overflow.
Insulation resistance: the insulation resistance between the metal work piece and the earth is greater than 20kM.
Pressurization: there is no breakdown or flashover under 15kVdc/1min between the metal work piece and the earth.
The curvature radius of the fiber 40mm, without extra loss inside the splice tray.
It can bear the axial tensile strength no less than 1000N.
