一种采用16芯光纤带的高密度光缆目前已经被研制出来,光纤带由涂覆层很薄的仅为200μm的光纤组成。对于16芯和80芯单模光纤连接器而言,平均光损耗分别达到0.2和0.35dB。光缆接续时间已减少到目前需要的1/5。通过对纤芯和包层材料的粘度匹配,减少了光纤的结构不完整损耗。经过改变沿光缆长度方向的布里渊频移,光缆的有效输入功率提高了7dB。
A high-density fiber optic cable with a 16-core fiber ribbon has now been developed that consists of a very thin coating of only 200 μm of fiber. For 16-core and 80-core single-mode fiber connectors, the average optical losses reach 0.2 and 0.35 dB, respectively. Cable connection time has been reduced to the current needs of 1/5. By matching the viscosity of the core and cladding material, the structural loss of the optical fiber is reduced. After changing the Brillouin frequency shift along the length of the optical cable, the effective input power of the optical cable is increased by 7 dB.
