Phalo/OSD公司宣布,该公司研制出 DO12、DO22 SS系列大芯径光缆。该光缆采用100微米芯径、140微米包层的全玻璃光纤。此种新型光缆含有中带宽、大数值孔径、易以连接与终端的半渐变型光纤。该光缆具有100兆赫/公里的带宽,从而填补了宽带宽渐变型光纤和窄带宽突变型光纤之间的空隙,其数值孔径选择为0.2、0.25和0.3,因而可将价廉的发光二极管用作光源,尤其在短途数据线路和工业生产控制方面。该光缆由一坚固缓冲管构成,管内的缆芯四周包有芳族聚酰胺光纤,这种结构对于机械与挤压损坏起到极好的防护作用。此外,用阻燃聚氯乙烯护套作为光缆的总绝缘。
Phalo / OSD announced that the company has developed the DO12, DO22 SS series of large-core optical cable. The cable uses 100 micron core diameter, 140 micron cladding all-glass fiber. The new cable contains medium bandwidth, large numerical aperture, easy to connect and terminal semi-tapered fiber. With a bandwidth of 100 MHz / km, the cable fills the gap between wide-bandwidth tapered fibers and narrow-bandwidth abrupt fibers with numerical apertures of 0.2, 0.25 and 0.3, making inexpensive light-emitting diodes Light sources, especially in short-haul data lines and industrial production controls. The cable consists of a rigid buffer tube surrounded by aramid fibers inside the tube core, this structure for the mechanical and extrusion damage played an excellent protective effect. In addition, with a flame retardant PVC sheath as the total insulation of the optical cable.
