Fiber G657A2

The bending insensitive single-mode optical fiber G.657.A2, is available in 200 μm & 245 μm diameters. Since dedicated high-performance acrylic composites are used for coating protection, the fiber still has outstanding bending loss characteristics while reducing the size. Small size optical fiber can save a lot of space occupancy of pipeline and increase the core capacity of cable, which is the best choice for pipeline network.

our company

30+ years

Our factory was found in 1992, first start with coaxial cable which was one of the biggest manufacturers in lin'an city.In year of 2001 started focusing on the production of optical cables.

30+ countries

In year of 2008, set up international sales department and sale optical fiber cable to more than 30 countries and have 18 years` rich experience to export cables .

Features

Good bending loss characteristics, less bending loss.
Smaller fiber sizes of 200 μm are available, and the design cross-sectional area of the cable is reduced by more than 30%.

Application Scenarios

• High density metropolitan area network and narrow space access network
• Blowing tiny cables
• FTTx
