G657A1 Low Loss Bending Insensitive Single-mode Fiber

Optical fibers are basically composed of two coaxial layers: core and cladding. The core is the inner part of the fiber, which guides light, whereas the cladding surrounds it completely.

Feiboer provides the whole series of SMF products that meet and even excel the requirements of standards on performance indicators. Due to the high stability, these products effectively meet the demand for high speed, large capacity, long distance and small bending radius necessary for signal transmission in different applications.

Low Loss Bending Insensitive Single-mode Fibre is suitable for optical transmission systems which operates over the entire wavelength window from 1260 nm to 1625 nm. It is an advanced product of Feiboer bending insensitive fibre, which possesses all advantages of Low Loss Fibre, and also improves anti-bending properties, combines low loss and bending insensitive properties. Feiboer Low Loss Bending Insensitive Single-mode Fibre is fully compatible with standard normal single-mode Fibre, and thoroughly meets multiple demands of multi-channel, high bit-rate, long distance transmission and anti-bending properties.
