Specification
SDGI’s ultra-fine series of single-mode optical fibers (200μm G.657A1) through a unique coating system design and curing process technology, while reducing the outer diameter of the optical fiber coating, the optical and transmission performance, mechanical and environmental performance meets or optimize It is compatible with conventional 245μm G.657A1 optical fiber technical specifications such as ITU-T G.657.A1, IEC60793-2-50 B6.a1, etc.
SDGI 200μm G.657A1 can provide the best transmission performance in the full range of 1260nm-1625nm, especially in the L-band long-wavelength window transmission, with excellent macro bending performance. The optical fiber also has low attenuation, low PMD, and excellent geometric dimensions. The unique coating process of the optical fiber not only provides excellent macro bending performance, but also ensures the reliability and durability of the optical fiber, and can provide the best performance even in the harshest environment.
SDGI 200μm G.657A1 non-dispersion shifted single-mode fiber has a small outer diameter and excellent macro-bending performance (minimum bending radius of 10mm), which can support a smaller cable bending radius and smaller optical fiber distribution box. It is especially suitable for large core count cables, Micro cables used in access networks, and indoor networks (FTTH).
Product Features
