48FO (4X12) Duct Flex tube Fiber Optic Cable OS2 G.657.A1 LSZH Dielectric Unarmoured Yellow

Fiber Type (ITU) - OS2 G.657.A1

Each type of single-mode fiber has its own area of application, and the evolution of these optical fiber specifications reflects the evolution of transmission system technology from the earliest installation of single-mode optical fiber to the present day. Choose the right fiber is very important for each project/installation. The OS2 G.657 standard single-mode fibers were developed to allow a better bending radius regarding the G.652 standard. For the OS2 G.657 fiber there are 4 subcategories: G.657.A1, G.657.A2, G.657.B2, G.657.B3. The G.657.A1 fiber type is characterized by 10 mm minimum bending radius. These specifications of the G.657 fibers allow to have a better cost-efficiency due to compact cable designs and reduced space requirements.

FOC Construction - Flex tube

While using a flex tube construction in cables, you can:

• Reduced installation time;
• Easier handling, particularly in fiber distribution and termination units;
• Fast access to fibers; easy to remove the module material with no tools required;
• Small quantity of grease, minimizing clean-up time;
• Avoid the risk of tube kinking (potentially causing attenuation increments or fiber breakage);
• Simple mid-span breakout enabling single module extraction to aid distribution.

The cable flex tube construction solution can be chosen for the following applications:

• Direct buried;
• Rodent resistant;
• Gunshot resistant;
• Facade;
• Indoor and outdoor;
• Hybrid;
• Underwater;
• Tunnel.

FOC Protection - Dielectric Unarmoured

Dielectric unarmoured is a type of fiber optic cable protection that provides electrical isolation without the added mechanical protection of an armor layer. This type of protection is achieved by using dielectric materials such as aramid yarns or glass fibers to provide strength to the cable. Dielectric unarmoured FOC is typically used in indoor installations, where the cable is not exposed to the same level of mechanical stress and environmental factors as outdoor installations. It is also used in applications where weight and flexibility are a concern, such as in aerospace or automotive industries.

Jacket Material - LSZH

LSZH (low smoke, zero halogen) is a jacket material that is designed to limit the release of smoke and toxic fumes in the event of a fire. It is made without halogens, which makes it environmentally friendly and safe for human health. LSZH is highly resistant to moisture and chemicals, making it suitable for harsh environments. It is commonly used in public buildings, transportation systems, and other areas where safety is a primary concern. However, LSZH may be more expensive than other materials, and it may have a lower temperature rating, which may limit its use in certain applications.
