Test method for coaxial cable structural return loss
同軸電纜結構回波損耗試驗方法Commercial building telecommunications cabling standard - part 2 : balanced twisted - pair cabling - addendum 3 - additional considerations for insertion loss and return loss pass fail determination
商用建築電信電纜敷設標準.第2部分:對稱雙絞合線電纜敷設.補充件3 .插入損耗和回波損耗通過失效確定的附加考慮要素With the increasing of digital cable transmission frequency, srl ( structural return loss ) on - line evaluation using diameter data of digital cable core became a method of cable quality control. higher measuring precision and higher measuring speed of the diameter gauge was required
此外，由於數字通信電纜傳輸頻帶的提高，對均勻性要求也不斷提高，採用直徑信息來在線評估數字通信電纜的srl （結構回波損耗）成為也質量控制一種方法，這就對測徑儀的測試性能提出了更高的要求。Than adopt aluminium bring or weave with aluminium foil cable have shielding not to be performance fine, decay little, return waves echo loss performance kind merit, its product parameter has already reached the international similar products level
比採用鋁帶或編織加鋁箔的電纜具有屏蔽性能好、衰減少、回波損耗性能好等優點，其產品參數已達到國際同類產品水平。A few kinds of signal separate measures, double caner frequency automatc switch function and relay function are taken into account on the design of wfplc - ml iniddle - voltage distribution line carrier modem. coupling equipment is designed with the filter and capacitance fitted togethel in this papef, it is also advanced an scheme about caner signal spanning the distribution line break. the equipment system has been finished and put into use, which has better result. the feasibly and necessity of the studying of this problem are posed
Wfplc3510中壓配電載波系統利用10kv的架空線或電纜，將主控斷發出的命令信息轉換為載波信號通過三相耦合器耦合到電力傳輸線上，在被控端利用單相耦合器耦合到載波信號后轉換為介面信號發送給被控單元，被控單元亦可將返回數據通過單相耦合發送載波信號到主控端，實現信息的雙向傳遞。Coaxial cable pulse echo tester
