產(chǎn)品描述
G.657單模光纖有更好的抗宏彎性能,是一種彎曲不敏感的低水峰光纖,可充分利用O+S+C+L波段(1260~1625nm)傳輸。有較低的偏振模色散(PMD),可以滿足高速率、長(zhǎng)距離傳輸要求。目前G.657單模光纖有三種類別:G.657A1、 G.657A2和G657B3。
應(yīng)用環(huán)境
G.657單模光纖主要用于特殊用途的短距離光纜;在O+S+C+L波段工作性能優(yōu)異;FTTX高速光路由;還可以用于有較小彎曲半徑要求的光纜。
產(chǎn)品標(biāo)準(zhǔn)
G.657單模光纖按照標(biāo)準(zhǔn)制造,品質(zhì)優(yōu)于ITU-T建議的G.657和IEC 60793-2-50 B6類光纖技術(shù)規(guī)范以及國(guó)家標(biāo)準(zhǔn)GB/T 9771.7。
