基于特殊的彎曲不敏感光纖剖面設計,北億纖通165um小外徑彎曲不敏感光纖實現(xiàn)了將較小的光纖外徑同彎曲不敏感特性的完美結合, 而且通過減小外包層的厚度,光纖玻璃部分直徑中心值僅有80um的同時,光纖模場直徑與常規(guī)G.657.B3光纖相當。
北億纖通165um小外徑彎曲不敏感光纖在彎曲半徑低至5毫米時依然具有極低的彎曲附加衰減,同時保持與傳統(tǒng)G.652.D和G.657的兼容,適用于對光纖尺寸、光纖彎曲半徑有嚴苛要求的應用場景。
產品應用
● 小型化光器件
產品特點
● 優(yōu)異的彎曲性能并與G.652.D和G.657兼容。
● 光纖通過200KPSI張力篩選,確保了可靠性。
● 光纖橫截面積相對于標準光纖減小了56%,有利于光器件的小型化。
