基于特殊的彎曲不敏感光纖剖面設(shè)計(jì),北億纖通165um小外徑彎曲不敏感光纖實(shí)現(xiàn)了將較小的光纖外徑同彎曲不敏感特性的完美結(jié)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(shí),光纖模場(chǎng)直徑與常規(guī)G.657.B3光纖相當(dāng)。
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(shí)依然具有極低的彎曲附加衰減,同時(shí)保持與傳統(tǒng)G.652.D和G.657的兼容,適用于對(duì)光纖尺寸、光纖彎曲半徑有嚴(yán)苛要求的應(yīng)用場(chǎng)景。
產(chǎn)品應(yīng)用
● 小型化光器件
產(chǎn)品特點(diǎn)
● 優(yōu)異的彎曲性能并與G.652.D和G.657兼容。
