Fiber Type (ITU) - OS2 G.652.D
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 specification of the OS2 fiber is generally considered as the SMF standard for the single-mode fiber. For the OS2 G.652 fiber there are 4 subcategories: G.652.A, G.652.B, G.652.C, G.652.D.
The OS2 G.652.D single-mode fibers are the most used type of fiber for networking and communications applications. The OS2 G.652.D fiber type provides a zero dispersion at 1310nm wavelength therefor it is optimized for operation in the 1310nm Wavelength. The regular performance remains on the 1550nm wavelength.
Benefits of using the OS2 G.652.D fibers:
- Backward compatibility with earlier versions;
- Lower system cost;
- Offers zero water peak and seamless splicing;
- Lower splicing losses;
- Supports longer cable runs.
FOC Construction - Loose tube
While using a loose tube construction in cables, you can:
- Pull and stretch without causing fractures from bending or tension;
- Have full resistant protection of the fiber core, cladding and coating (mechanical protection and UV protection);
- Reach optimized performances at extreme temperatures;
- Avoid the risk of environmental damage (including water damage).
The loose tube construction solution can be chosen for the following applications:
- Direct buried;
- Aerial;
- Duct;
- Rodent resistant;
- Indoor and outdoor;
- Water-blocking;
- Temperature endurance.
FOC Protection - Dielectric Armoured
Dielectric Armoured is a type of fiber optic cable protection designed to provide a high degree of mechanical protection while maintaining electrical isolation. This protection is achieved by using an armor layer made of dielectric materials such as Kevlar, which is non-conductive and non-magnetic. This armor layer protects the cable from damage caused by crushing, impacts, and bending, while also providing protection from environmental factors such as moisture and temperature changes. Dielectric armored FOC is commonly used in indoor and outdoor installations where the cable may be exposed to harsh conditions.
Jacket Material - LSZH
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.
Fiber Mode - Single Mode (SM)
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.
