The 12FO (1x12) Direct Burial Loose Tube Fiber Optic Cable SM G.657.A1 Dielectric Armoured (Part number: 60063074) from Prysmian with 12FO. Direct buried cable is optimised for injection into ducts in optical networks and is usually directly buried or installed in ducts by air-blowing, jetted, pulled or pushed into the duct.
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.
