室内光纤电缆和户外光纤电缆不同

中(zhong)心(xin)内(nei)(nei)部(bu)电(dian)(dian)(dian)缆(lan)(lan)内(nei)(nei)部(bu)的(de)电(dian)(dian)(dian)缆(lan)(lan)通(tong)常(chang)由玻璃破(po)碎,芯外(wai)(wai)部(bu)包围的(de)折(zhe)射率低于玻璃外(wai)(wai)壳(qiao)(qiao)的(de)核心(xin)层,使光信号进入(ru)芯包层界面,光信号在(zai)光纤(xian)(xian)中(zhong)传播(bo)核心(xin)。因为(wei)电(dian)(dian)(dian)缆(lan)(lan)本身是非常(chang)脆弱的(de),不能(neng)直接应用于接线系统,所以(yi)通(tong)常(chang)捆绑在(zai)保护外(wai)(wai)壳(qiao)(qiao)外(wai)(wai)面,询问(wen)电(dian)(dian)(dian)缆(lan)(lan)电(dian)(dian)(dian)阻,这被称为(wei)户外(wai)(wai)光纤(xian)(xian)电(dian)(dian)(dian)缆(lan)(lan)通(tong)常(chang)包含一个或多个光纤(xian)(xian)电(dian)(dian)(dian)缆(lan)(lan)。根据(ju)不同的(de)环(huan)境,您可以(yi)将电(dian)(dian)(dian)缆(lan)(lan)插入(ru)室内(nei)(nei)光纤(xian)(xian)电(dian)(dian)(dian)缆(lan)(lan)和户外(wai)(wai)光纤(xian)(xian)电(dian)(dian)(dian)缆(lan)(lan)。

室(shi)(shi)内光缆(lan)(lan)抗(kang)拉强(qiang)度小,层(ceng)差,但(dan)更轻(qing),更经济。室(shi)(shi)内光缆(lan)(lan)主要用(yong)于垂直(zhi)和水平布线子系(xi)统(tong)的(de)主要子系(xi)统(tong)。 •大型户(hu)外(wai)光缆(lan)(lan)的(de)抗(kang)拉强(qiang)度,保护层(ceng)厚,通(tong)常为铠装(金属包(bao)装)。室(shi)(shi)外(wai)光缆(lan)(lan)用(yong)于复杂系(xi)统(tong),可用(yong)于户(hu)外(wai)直(zhi)埋,铺设,空中(zhong)和水下(xia)管道等。
