Fiber optic splice protectors from the V24 Series are widely used across various fields of fiber optic technology. They are employed to secure connections in hermetic splice closures, panel switches, rack-mounted, and hanging configurations. Their excellent climatic and thermal properties make them suitable for both indoor and outdoor applications. The primary advantages of this solution are connection rigidity and quick installation. During the design stage, the main objectives were to ensure complete protection of spliced optical fibers, connection rigidity, and short installation time.

The V24 Series is characterized by connection rigidity, relatively small external diameter after shrinking (D=2.4mm), reduced length (shortest L=20mm), and quick installation (up to 60 seconds). The construction of the sleeve consists of a reinforcing wire with a diameter of 1mm, an outer coating with a thin wall, and an inner coating with a 1.4mm hole. This design allows the use of sleeves for protecting fibers with a 250um coating as well as those with a 900um buffer. The inner coating is made of synthetic material with good adhesion to various materials and low water solubility. As the temperature rises, it changes its consistency to a flowing one. This allows for precise filling of the space between the inner wall of the outer coating, the wire, and the fiber, eliminating the formation of air bubbles. The reinforcing wire, which stiffens the connection, is made of steel with the same coefficient of thermal expansion as the optical fiber. This prevents the formation of longitudinal stresses during the heating process. Longitudinal stresses affect the increase of secondary and reflective attenuation of the connection. In extreme cases, they can lead to the breaking of the connection, necessitating the repetition of the splicing procedure. The material of the outer coating ensures durability and resistance to stretching and puncture. It is characterized by optimal air permeability, high gloss, and a smooth surface. It complies with the UL224 and MIL-I-23053 standards. The sleeve is typically produced in a transparent color, but other colors are available upon special order.
