產(chǎn)品優(yōu)勢
● 更大的有效面積,可減小非線性效應(yīng),為傳輸系統(tǒng)提供更高的信號功率
● 實(shí)現(xiàn)長距離、多波長、高速傳輸
● 更低的衰減損耗,滿足長距離傳輸要求
● 可減少中繼器數(shù)量,實(shí)現(xiàn) CAPEX、OPEX 最小化
● 更低的彎曲附加損耗,滿足復(fù)雜的光纜布線條件和各種光纜結(jié)構(gòu)的要求
● 良好的抗氫損性能,高 nd 值,以保證光纖光纜系統(tǒng)的可靠性
● 兼容當(dāng)前系統(tǒng),并滿足未來系統(tǒng)和技術(shù)發(fā)展的要求
如何評估有效面積和衰減系數(shù)對傳輸?shù)呢暙I(xiàn)?
根據(jù) OSNR 的公式,更低的衰減系數(shù)和更大的有效面積會提高光傳輸系統(tǒng)的光信噪比。所以可以通過建立 FOM(品質(zhì)因數(shù))來量化計(jì)算有效面積和衰減對光信噪比的貢獻(xiàn)。如下表所示,北億纖通超強(qiáng)光纖可以提供比超低衰減光纖或低衰減大有效面積光纖更好的性能。
