G.657.A2 Bending Insensitive Single-mode Optical Fiber

The bending insensitive single-mode optical fiber G.657.A2, is available in 200 μm & 242 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.

Application Scenarios

> High density metropolitan area network and narrow space access network

> Blowing tiny cables

> FTTx

Performance Features

> Specialized resin composite material and smaller bending loss properties

> The smaller size optical fiber is optional. Reduce the cable sectional area for more than 30% and the density of the cable is increased, which can effectively save pipeline resource
