• The cabinet is cold-rolled steel or SMC material, beautiful appearance. It can be moisture-proof, waterproof, dustproof, salt spray proof, corrosion resistance and aging resistance, and the protection level is IP65.
• It can support the direct fusion and storage of rest optical cable.
• The splicing trays can be taken out from the cabinet for operation.
• Suitable for ribbon cable and non-belt cable.
• Card-mounted installation of FC, SC adapters, easy and fast operation.
• The adapter is at an angle of 30° to the front of the cabinet, and the curved radius of curvature of the optical fiber is ≧40 mm, and the arc in the optical fiber is prevented from burning the eyes;
• The distribution and scheduling of optical fibers are all positive operations.
