光纖具有很寬的光譜帶寬和優(yōu)越的光學特性,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(SONET)和波分復用系統(tǒng)(WDM)等不同傳輸技術的最佳選擇。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,滿足了語音、數(shù)字、圖像傳輸?shù)榷喾N業(yè)務對帶寬資源的要求。
光纖適用于各類光纜結構,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。
● 低水峰單模光纖符合或優(yōu)于ITU-T G.652.D 和IEC 60793-2-50 B1.3型光纖技術規(guī)范。
● 北億纖通對光纖產(chǎn)品的各項指標制定了更嚴格的標準。
