The 24FO (1X24) Direct Buried Central Tube Fiber Optic Cable OS2 G.657.A1 LSZH Metallic Armoured Yellow (Part number: K1FBWF2024YLA5/1A) from KDP with 24FO and Metallic Armoured construction . 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.
The 24FO (1x24) Duct Central Loose Tube Fiber Optic Cable SM G.657.A1Yellow from KDP is a Duct cable with 24 fibers within 1 central loose tube. The optical fibers comply with ITU-T recommendations G.657.A1.
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.
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.
