The 8FO (2x4) Riser Flex Tube Fiber Optic Cable SM G.657.A1 (Part number: 60031645) from Prysmian with 8FO. Riser fiber optic cable is used in indoor and outdoor optical networks, more specifically in LAN backbone, access and riser zone. Riser cables are being used more and more in big projects outdoor that's why this type of cable benefits from a special jacket for different necessities.
The 8FO (2x4) Riser Fiber Optic Cable G.657.A1 from Prysmian is a Riser cable with 8 fibers within 2 flex tubes. This distribution cable for optical networks has a micromodule structure (flex tube construction) with a glass fiber reinforced with plastic material embedded in the outer sheath and a LSZH-FR material with longitudinal markers in order to position the cable opening window on the outer sheath. The optical fibers comply with ITU-T recomendations G.657A1.
For indoor use; Installation on cable tray, in corridors or shafts. Possibility of removing 6m of a module for mid span connexion at the floor without necessity to dispose of an over-length of cable.
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.
