產(chǎn)品應(yīng)用
北億纖通低損耗單模光纖具有很寬的光譜帶寬和優(yōu)異的衰減性能,是支持以太網(wǎng),互聯(lián)網(wǎng)協(xié)議(IP)、異步傳輸模式(ATM)、同步光網(wǎng)絡(luò)(SDH)和波分復(fù)用系統(tǒng)(WDM)等不同傳輸技術(shù)的最佳選擇。北億纖通低損耗單模光纖為骨干網(wǎng),城域網(wǎng)和接入網(wǎng)提供了更大的帶寬資源和更低的信號(hào)衰減,在滿足語(yǔ)音、數(shù)字、圖像傳輸?shù)榷喾N業(yè)務(wù)對(duì)帶寬資源要求的同時(shí), 也滿足了超長(zhǎng)距離傳輸對(duì)光纖衰減水平的要求。
北億纖通 低損耗單模光纖適用于各類光纜結(jié)構(gòu),包括光纖帶光纜、松套層絞式光纜、骨架式光纜、中心束管式光纜和緊 套光纜等。
產(chǎn)品標(biāo)準(zhǔn)
北億纖通低損耗單模光纖符合或優(yōu)于 ITU-T G.652.D 和 IEC 60793-2-50 B1.3 型光纖技術(shù)規(guī)范。
北億纖通科技有限公司對(duì)光纖產(chǎn)品的各項(xiàng)指標(biāo)制定了更嚴(yán)格的標(biāo)準(zhǔn)。
