ULTIMODE UNI-8SM is a universal fiber optic cable for indoor and outdoor applications. Single-mode 250 μm fibers are contained in central gel-filled tube. The gel in the tube is a kind of protective coating for optical fibers, which absorbs mechanical stresses and protects against environmental factors. The aramid yarn is designed to protect the central tube and fibers from mechanical damage, including risks posed by rodents.
ULTIMODE UNI-8SM cable contains 8 single-mode fibers. The color identification of the buffer layers complies with the GB13993.3-2001 standard. The jacket (sheath) is made of low smoke zero halogen flame retardant poly-olefin (LSZH).
The single-mode fibers used in the cable are ITU-T G.652.D, in 250 μm tight buffers. The G.652.D fibers are currently the most popular single-mode fibers, thanks to reduced water peak attenuation and capability of using within the whole 1280 nm to 1625 nm wavelength range. The G.652.D fibers are optimized for transmission at the wavelengths of 1310 nm (attenuation less than 0.36 dB/km) and 1550 nm (attenuation less than 0.22 dB/km), but they can be used at any wavelengths within the 1280-1625 nm range. The fibers are made in accordance with IEC 60793-2-50, EIA / TIA-FOTP and ITU-T G.652.D standards.
Universal cables from ULTIMODE UNI series are gel-filled fiber optic cables intended for horizontal connections in buildings and outside buildings. Due to the small size and flexibility, the cables are ideal for installation in cable ducts. They are used in modern FTTH and FTTB systems, in server rooms, between buildings.
