Ribbon Fiber Optic Fusion Splice Prot. Sleeves L=40mm D=5,5mm Clear

Product description
VRB RIBBON LOOSE series sleeves are applied in bar fiber-optic cables of the RIBBON type. They enable to secure up to twelve fibers in one shield. VRB series have been equipped with two ceramic strengthening elements in order to minimize stresses. However, this increased the sleeve diameter to 6.4mm. 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, minimizing stresses 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 elements from falling out. The final product is checked to meet the requirements set ZN-96TPSA-006 standard of Polish Telecommunications. The sleeves we produce offer full protections 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 increased size (D=6.4mm after shrinking), the ability to secure up to 12 fibers in one sleeve and quickness of assembly (below 95s). The sleeve consists of two D-shaped ceramic strengthening elements (dimensions 1.8x4mm), a thin external tube and an internal tube with a 1.3x4mm hole. Such a solution enables using those sleeves to protect bar fiber-optic cables with a 250um cover and a 900 um buffer. The internal tube is made from special material 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 ceramic 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 material guarantees sustainability and resistance to stretching and puncture. It offers optimal air permeability, high gloss and smooth surface.

The standard sleeves are made in clear color. Other color available on request.
