双层铠装尾纤光纤跳纤室内光缆水下光缆
室内光缆分为两大类:
一类为跳接纤尾纤(单芯或双芯光纤)光缆,可以采用多模或单模光纤。
另一类为配线光缆(2或72芯)
两类光缆的基本元件类似，都采用直径900 ±50um紧套光纤，外绕芳纶提供加强，并最后挤塑阻燃PVC护套。为了区别的方便，护套的颜色取决与光纤的类型，桔色护套用于多模光纤(EIA-359-1,黄色护套用于单模光纤(EIA-359-A),这些光缆能用于智能楼宇布线系统，能提供满足防火标准的标准。比如压力通风管系统用光电缆(OFNP-UL910),上升光缆(OFNR-UL1666)或一般用途光缆(OFN-UL1581)对于楼房/室外光缆要求使用标准的中心束管式和松套层绞式结构，有时外加防火护套。
Two distinct categories,one being Patch Cord(single or dual fibre)and the other classified as Distribution cable (2 or 72 fibres).They can be supplied with multimode or singlemode fibres.
The principal components of the cables are similar.They utilise tight buffered fibres(diameter 900±500um)with an
outer covering of aramid yams to provide strength and then finally a flame retardant PVC sheath.To assist in
iden-tification the sheath colour depends on the type fibre within the cable.Orange colour for multimode fibres
(EIA-359-A) and yellow for singlemode fibres (EIA-359-A).These cables can also be used as risers(for cabling between floors).Cables can be supplied to meet specific fire protection standards,i.e.
Plenum calbe(OFNP-UL910),Riser(OFNR-UL1666)or General purpose cables(OFN-UL1581).
For Premise/Outdoor cable requirements then standard Central Loose Tube and Stranded Loose Tube products can be used,some-times with a fire-resistant sheath.
