The 144FO (12x12) Duct Loose Tube Fiber Optic Cable SM G.657.A1 Metallic Armoured (Part number: 60043922) from Prysmian with 144FO and Metallic Armoured construction. 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.
The 144FO (12x12) Duct Fiber Optic Cable G.657.A1 Metallic Armoured from Prysmian is a Duct cable with 144 fibers within 12 loose tubes. This distribution cable for optical networks has a loose tube structure with thermoplastic material, containing optical fibers that is filled with suitable water tightness compound and a inner polyethylene sheath with two ripcords beneath and a outer HDPE with graphite coating with both sides with copolymer coated corrugated steel tape with overlap,(steel thickness: 0.15 mm. 2 ripcords beneath the tape). It has also aramid yarns as peripheral strenght elements. The glass fiber is reinforced with plastic rod (FRP), with plastic oversheathing when needed. The optical fibers comply with ITU-T recomendations G.657A1.
For outdoor use.
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.
While using a loose tube construction in cables, you can:
The loose tube construction solution can be chosen for the following applications:
Metallic Armoured is a type of fiber optic cable protection designed to provide a high degree of mechanical protection against impacts, crushing, and other hazards. This protection is achieved by using an armor layer made of metal wires, tapes, or corrugated steel, which provides a high level of strength and durability. Metallic armoured FOC is commonly used in outdoor and industrial applications where the cable is exposed to harsh environments, such as oil rigs, mining operations, and military installations. This type of protection also provides additional protection against electromagnetic interference and other sources of signal distortion.
