GYDGA 光纜的結(jié)構(gòu)如下：光纖帶放入由高密度聚乙烯 (HDPE) 制成的骨架槽內(nèi)，骨架中心是單根鋼絲或多股絞合鋼絲。在骨架外繞包一層阻水帶，雙面涂塑鋁帶 (APL) 縱包后擠制聚乙烯 (PE) 護(hù)套。在鋁帶與阻水帶之間放置撕裂繩以便于護(hù)套開(kāi)剝。

產(chǎn)品應(yīng)用
GYDGA 光纜具有光纖組裝密度高、抗側(cè)壓性能好、接續(xù)效率高等優(yōu)點(diǎn)，充分滿足現(xiàn)代通信發(fā)展（如 FTTB、FTTH等）對(duì)施工和通信能力的要求，特別適用于中繼網(wǎng)和接入網(wǎng)。

產(chǎn)品特點(diǎn)
● 良好的結(jié)構(gòu)設(shè)計(jì)和工藝控制，具有優(yōu)越的光學(xué)、機(jī)械和環(huán)境性能
● 采用快速高膨脹率阻水帶，充分保證了光纜的阻水性能
● 采用無(wú)纖膏和纜膏的全干式阻水結(jié)構(gòu)，克服了傳統(tǒng)油膏不易清除的缺點(diǎn)，減少了施工準(zhǔn)備時(shí)間，極大地提高了接續(xù)效率，便于施工和維護(hù)
● 骨架式結(jié)構(gòu)抗側(cè)壓性好，對(duì)光纖帶有良好的保護(hù)
● 光纖組裝密度高，光纜相對(duì)直徑小，重量輕，便于敷設(shè)
● 骨架式結(jié)構(gòu)開(kāi)剝后，可直接取出光纖帶，便于分歧
● 護(hù)套內(nèi)放置撕裂繩，便于開(kāi)剝

結(jié)構(gòu)參數(shù)

注: a．Xn代表選用光纖類(lèi)型，光纖色標(biāo)參見(jiàn)光纖帶說(shuō)明
