Bend Insensitive single-mode fiber G.657.A2-Single-mode fiber-Xi 'an Xigu Optical Communication Co., LTD

Description

Product Description

G.657.A2 bend-insensitive single-mode fiber is available in 200 μm and 242 μm diameters. The coating protection of high-performance resin composites enables 200μm fibers to have excellent flexural loss characteristics at reduced size, making them the best choice for broadband construction in metro and access networks.

Product Features

"1"

Good bending loss characteristics, less bending loss.
"2"

Smaller 200μm fibers are available, reducing the cross-sectional area of the cable design by more than 30%.
