48FO (6x8) Riser Flex Tube Fiber Optic Cable G.657.A2

Fiber Type (ITU) - OS2 G.657.A2

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.A2 fiber type is characterized by 7.5 mm minimum bending radius. These specifications of the G657 fibers allow to have a better cost-efficiency due to compact cable designs and reduced space requirements. Find some benefits when using the G.657.A2 fiber type:

• Low attenuation;
• Excellent macrobend performance (low bending radius);
• Flexibility;
• Cost-efficiency.

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.

Fiber Mode - Single Mode (SM)

Single mode fiber uses a LASER light source, is a type of optical fiber with a small core diameter that allows only one mode of light to propagate. It is used in telecommunications and data transmission systems to transmit signals over long distances with low attenuation and high bandwidth. Single mode fiber is ideal for high-speed and long-distance applications, such as internet backbone networks, cable television networks, and fiber-to-the-home (FTTH) services. Its narrow core reduces the dispersion of light, allowing signals to travel further and faster than with multimode fiber.
