PRODUCT DESCRIPTION
VRB RIBBON series protectors are applied in ribbon fiber optic cables of the RIBBON type. They enable to secure up to twelve fibers in one protector. Excellent climatic and thermal properties make it ideal for use in closed as well as open spaces. The main goals during design phase were: full protection of the fiber optic splices and quickness of assembly. Initial shrinking of the sleeve was taken into account during the production process to reduce the gap between the tubes. This protects the internal tube and ceramic strengthening element from falling out. The final product is checked to meet the requirements set by the EN 50411-3-3 European Standard and GR-1380-CORE American Standard. The sleeves we produce offer full protection to the fiber optic splices. They do not cause additional insert losses, and they offer protection against mechanical damage, pollution and weather conditions.
VRB series is characterized by: ability to secure up to 12 fibers into one protecor, quickness of assembly (60s). External diameter: VRB4 3.4×3.1mm, VRB8 4.4×4.0mm, VRB12 5.1×5.7 after shrinking. The sleeve consist of: two D-shaped ceramic strengthening elements (dimensions: VRB4 1.5x3mm, VRB8 and VRB12 2x4mm), a thin external tube and an internal tube with a 2mm wide opening for up to 4 fibers or 1×2.5mm wide opening for up to 8 fibers or 1×3.4mm wide opening for up to 12 fibers. The protectors are dedicated to primary coated 250µm (ribbon fiber). The internal tube is made from special material EVA with good adhesion to many materials and low solubility in water. It changes its consistency to semi-liquid in growth temperatures. It enables to eliminate air bubbles through filling up the spaces between external tube, the Pin and fiber optic cable. The Pin that stiffens the splice is made from ceramik 95% Al2O3 Helf Cylinder with heat extensibility indicator identical to that of optic fiber. This prevents from longitudinal stresses on the splice during heating process. Longitudinal stresses of the splice influence on growth a insert loss and a reflection loss. In extreme cases they may cause breaking the connection, which makes it necessary to repeat the splice procedure. External tube made from PEX, cross linked polyethylene. The material guarantees sustainability and resistance to stretching and puncture. It offers optimal air permeability, high gloss and smooth surface.
