Description

G.657.A1 bend insensitive single mode fiber

product-1057-327

Product Introduction

Product Application

Due to the excellent attenuation and bend-insensitive performance of G657.A1 bend-insensitive single-mode fiber, it can be fully compatible with different cabling systems in backbone networks, metropolitan area networks, access networks, and indoor installation environments.

Product Features

• Excellent bend-insensitive and low-loss performance

• Achieve transmission in the full band of 1260nm to 1625nm, improve system transmission capacity with low dispersion and PMD, meeting the needs of long-distance transmission

• Fiber can effectively suppress bend loss in small radius bending situations

• Accurate geometric parameters ensure low fusion loss and high fusion splicing.
