全光纤衰减速器袖珍全光纤衰减器用于远距离通讯、电缆电视以及数据网络系统，产生很低的背反射。固定数值的外建和在线衰减器使用熔融光纤技术。这种技术依靠渐逝耦合的自然特性，在１～３０ｄＢ预固数值内产生损耗。可变数值的在线衰减器利用调节螺钉改变特制光纤弯曲半... All Fiber Attenuators Compact all-fiber attenuators are used for long-distance communications, cable television and data networking systems, resulting in very low back reflections. Fixed-value external and on-line attenuators use fused-fiber technology. This technique relies on the natural characteristics of evanescent coupling, producing losses at pre-solid values ​​of 1 to 30 dB. Variable value of online attenuator using adjusting screw to change special fiber bending half ...
