16FO (4x4) Riser Flex Tube Fiber Optic Cable SM G.657.A2 LSZH

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.
