產(chǎn)品描述
G.652D單模光纖,適用于1260~1625nm全波段的傳輸系統(tǒng)。該單模光纖抑制了普通單模光纖在1383nm附近由于氫氧根離子吸收造成的水峰損耗,將工作窗口擴(kuò)展到了E波段(1360~1460nm),從而增加了約100nm的光譜帶寬。G.652D單模光纖全面優(yōu)化了1260~1625nm 波段的衰減性能和色散性能,并提高了L波段(1565~1625nm)的抗宏彎性能,充分滿足了在單根光纖上多信道傳輸高速率業(yè)務(wù)的需求。G.625D單模光纖是構(gòu)建網(wǎng)絡(luò)的理想選擇之一。
應(yīng)用環(huán)境
G.652D單模光纖,廣泛應(yīng)用于語(yǔ)音傳輸、數(shù)據(jù)、視頻等業(yè)務(wù),為客戶提供性價(jià)比高的優(yōu)質(zhì)產(chǎn)品。
產(chǎn)品標(biāo)準(zhǔn)
G.652D單模光纖嚴(yán)格按照***高標(biāo)準(zhǔn)制造,品質(zhì)優(yōu)于ITU-T建議G.652D和IEC60793-2-50B1.3類光纖技術(shù)規(guī)范以及國(guó)家標(biāo)準(zhǔn)GB/T 9771.1。
