Product Description

Bare Single-Mode G657A1 Bend-Optimized Low Loss Optical Fiber 

Product Description

Bending Insensitive Single-mode Fiber
Low Loss Bending Insensitive Single-mode Fiber 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 fiber, which possesses all advantages of Low Loss Fiber, and also improves anti-bending properties, combines low loss and bending insensitive properties. Low Loss Bending Insensitive Single-mode Fiber is fully compatible with standard normal single-mode Fiber, and thoroughly meets multiple demands of multi-channel, high bit-rate, long distance transmission and anti-bending properties.

    • Short pitch cables for special application
    • High performance optical network operating in O-E-S-C-L band
    • High speed optical routes in buildings (FTTx)
    • Cables with low bending requirements
Product standards: Low Loss Bending Insensitive Single-mode Fibre meets or exceeds the ITU-T Recommendation G.652.D/G.657.A1 including the IEC 60793-2-50 type B1.3/B6.a1 Optical Fibre Specification.


Due to its outstanding performance in both attenuation and bending resistance, EasyBand® Low Loss Bending Insensitive Single-mode Fibre is fully compatible with different cabling and differentiated systems in different installation environments of trunk network, metropolitan area network, access network and resident network.
