As the attenuator is used in the laser system for the on-line testing, there, therefore 3303 can be used in the digital system of communication devices (such as:PHD, SDH) and also in the system of adopting analog modulation (CATV)\u003c\/p\u003e \u003cp style=\"margin:10px 0;line-height:1.8;\"\u003e \u003cbr\u003e \u003cbr\u003e \u003cspan style=\"table-layout:fixed; WORD-WRAP:break-word;
