The author believe that copper cable will be replaced by fiber as the development of network, but now most fiber lan use a switch with fiber interface to get full - duplex operation, and the most important obstacle in deploying fiber lan is the high price of the switch. only some big company can afford the fiber switch and the switches often work in man. in order to lower the costs of gigabit optical lan, this paper presents a workgroup optical network base on passive star coupler ( psc )
作者堅信，隨著網路技術的發展，光纖一定會代替銅纜成為網路的主流傳輸介質，目前光纖本身的價格也可以為客戶所接受；但是影響光纖介質的局域網推廣普及的一個重要因素，就是目前市面上的光網路都採用了全雙工交換機，而光纖介面的交換機尤其是千兆位的交換機價格很高，多用於校園網或城域網；只有極少數大型企業能夠負擔，影響了光纖網路的部署。 -
The article consists of three parts mainly : the first part has described the method of detecting the faint signal, mainly include : detection technique of faint signal, principle of the optical fibre sensor, the little lose effects when optic fibre little curved, and the research of the stress sensor of optical fibre. the second part emphasizes on the design of the intelligent photoelectricity system, mainly tells the design of the circuit to process the faint photoelectricity signal, details the software and hardware design of intelligent photoelectricity system made of single chip microcontroller, led, man - machine interface, communication interface, etc. the third part is the network communication of the detection system, details the technology of single chip microcontroller how to group the network, and the communication between single the chip microcontroller system and the modem, and how to realize the data between the field and computer central exchanged through the existing public phone network
文章主要分為三部分：第一部分論述了微小信號的檢測方法，主要包括微小信號的檢測技術、光纖傳感器的原理、光纖微彎損耗效應及光纖應力傳感器的研製；第二部分重點講述了智能光電檢測系統的研製，主要講述了微弱光電信號調理電路的設計及由前（后）向通道、單片機、 led 、人機介面、通信介面等組成的智能光電系統的軟硬體的具體設計；第三部分為檢測系統的網路通信部分，具體闡述了單片機系統間的組網技術、單片機和modem之間的通信及通過現有的公用電話網路實現遠程監控的技術，實現現場檢測系統與橋梁測控中心的數據交換。 -
Nonlinear directional coupler ( nldc ) is a switch used in optical network. w. s. man had studied transmission controlling with ground state soliton through nldc, it is obviously not available to used in superhigh speed network ; and mary j. potasek had studied the self - coupling with ultrashort solitons in nldc, self - coupling is difficult to control the signal transmitting. i has studied the transmission controlling with ultrashort solitons ( < 100fs ) in nldc, similarly i use a controlling pulse to control the signal pulse, it is the intensity of controlling pulse to decide the signal change its direction or not
非線性定向耦合器（ nldc ）是用在光網路中的光開關器件，它主要用在全光網路中， w . s . man等研究過基態孤子在nldc中的傳輸控制，便於對全光網路中數據的正確傳輸，由於目前研究集中在100fs的超短脈沖傳輸特性上，顯然基態孤子的特點不再適用於超高速網路； maryj . potasek等就超短脈沖在nldc中的自耦合做了研究，在光網路中自耦合任意性太大，不利於控制脈沖的傳輸。 -
Not only was man now able to see with measured precision independently of visibility, but he could now “ see ” such objects as aircraft at ranges far in excess of those possible even under ideal optical conditions with normal vision
人不僅可以不受視線（能見度）的限制而看得很精確，並且可以「看見」諸如遠方的飛機等物體，其距離遠遠超過用正常的視力並藉助于最理想的光學儀器所能達到的。 -
The chief superintendent of organised crime and triad bureau, mr fung kin - man, said at a press conference today ( september 9 ) that the operation was aimed to combat organised crimes including triad and vice activities, illegal gambling and bookmaking, dangerous drugs, pornographic and pirated optical discs, copyright infringing goods, contraband cigarettes and unmarked oil as a means to severe their revenue source
警方有組織罪案及三合會調查科總警司馮建民今日（九月九日）在記者會上表示，是次聯合行動目的是針對有組織罪行，包括三合會及賣淫活動、非法賭博及外圍賭馬和賭波、毒品、色情及盜版光碟、翻版物品、私煙及非法燃油，以打擊三合會的收入來源。
