The 48FO (4x12) Indoor/Outdoor Loose Tube Fiber Optic Cable SM G.657.A1 LSZH Metallic Armoured (Part number: 60049676) from Prysmian with 48FO and Metallic Armoured construction . Indoor/Outdoor fiber optic cable is prepared for both environmental requirements, indoor and outdoor optical networks, which can be run in duct, direct buried or aerial in the outside plant. By installing this cable, there's no need of costly splice junctions when entering into buildings because of the adaptability of the cable.
The 48FO (4x12) Indoor/Outdoor Loose Tube Fiber Optic Cable SM G.657.A1 Metallic Armoured from Prysmian is a indoor/outdoor cable with 48 fibers within 4 loose tubes. This distribution cable for optical networks is a steel armoured flame retardant ALPA® optical cable, which allows this cable to be rodent and termite proof. It has a loose tube structure with thermoplastic material, containing optical fibres filled with suitable water tightness compound and a double sheath, an inner Multi-layer ALPA® sheath and an outer HFFR, UV/heat/oil resistant sheath. It has a glass fibre reinforced plastic rod as central strenght member and thermoplastic rods filler elements, where needed. Longitudinal Water Tightness, dry core with water swellable elements. The optical fibers comply with ITU-T recomendations G.657.A1.
For outdoor use; This cable is especially designed for harsh environments. Multi-layer inner sheath ALPA® is highly resistant to aggressive chemical constituents and fluids that might occur on (petro) chemical plants. Suitable for installation under and above ground.
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.
LSZH (low smoke, zero halogen) is a jacket material that is designed to limit the release of smoke and toxic fumes in the event of a fire. It is made without halogens, which makes it environmentally friendly and safe for human health. LSZH is highly resistant to moisture and chemicals, making it suitable for harsh environments. It is commonly used in public buildings, transportation systems, and other areas where safety is a primary concern. However, LSZH may be more expensive than other materials, and it may have a lower temperature rating, which may limit its use in certain applications.
Single mode fiber uses a LASER light source, is a type of optical fiber with a small core diameter that allows only one mode of light to propagate. It is used in telecommunications and data transmission systems to transmit signals over long distances with low attenuation and high bandwidth. Single mode fiber is ideal for high-speed and long-distance applications, such as internet backbone networks, cable television networks, and fiber-to-the-home (FTTH) services. Its narrow core reduces the dispersion of light, allowing signals to travel further and faster than with multimode fiber.
