YOFC Bare Fiber G.657A1 Low Loss Bending Insensitive Single-mode Fibre

Descriptions:

YOFC EasyBand® 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 YOFC bending insensitive fibre, which possesses all advantages of Low Loss Fibre, and also improves anti-bending properties, combines low loss and bending insensitive properties. EasyBand® 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.

Features:

Possesses advanced anti-bending and low loss properties
Achieved the operation over full optical spectrum from 1260nm–1625nm, and increased the system transmission capacity
Lower attenuation, which meets the demand of extended long distance transmission
Good bending loss resistance at short radius bends
Accurate geometrical parameters that insure low splicing loss and high splicing efficiency
