FTTH Fiber Cable Single Mode Outdoor Optical Drop Cable G.657 A2
TOEM ftth single mode fiber cable G.657 A2 provides high strength fiber optic cables suitable for a variety of industrial, indoor and outdoor applications.It fully complies with ITU-T G 657A2 standard and does not bend. Outdoor Ftth Fiber Cable has low water peak and strong macro-bending resistance.
The FTTH Single Mode Fiber Cable G.657 A2 complies with ITU-T recommendations G.652.D and G.657.A1, IEC international standard 60793-2-50 B.1.3 fiber specifications.
The fiber is manufactured using advanced VAD technology and has extremely fine refractive index distribution control. At the same time, FTTH Single-mode Fiber Optic Cable has excellent geometric performance and low attenuation characteristics.
FTTH Fiber Cable is designed for use in the wavelength range of 1260nm to 1625nm, and has completely low attenuation in the 1383nm region. At the same time, it has excellent bending performance and can adapt to special occasions with requirements for bending radius.
Outdoor FTTH Single Mode Fiber Cable has precise geometric parameters to ensure low splicing loss and high splicing efficiency. At the same time, it is compatible with existing G.652D optical fibers, and its excellent PMD factor supports high-speed and long-distance upgrades.
