The 144FO (12x12) Duct Loose Tube Fiber Optic Cable SM G.657.A1 Metallic Armoured (Part number: 60023574) from Prysmian with 144FO. Conduit cables are underground cables, that may be conducted by duct or buried directly into the ground. There are several types of protections for this cable such as anti-rodent or double protection. Conduit cables are built to withstand harsh environments and are typically routed by pull or blow.
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.
