ENTERASYS A4H254-8F8T 交換機

1級激光收發(fā)器使用光學反饋回路來維持1級操作限制。該控制回路無需進行維護檢查或調(diào)整。輸出為出廠設置，不允許用戶進行任何調(diào)整。1類激光收發(fā)器符合以下安全標準：?21 CFR 1040.10和1040.11美國衛(wèi)生與公眾服務部（FDA）。?IEC出版物825（國際電工委員會）。?CENELEC EN 60825（歐洲電工標準化委員會）。當在其性能限制范圍內(nèi)工作時，激光收發(fā)器輸出滿足所有三個標準的1級可訪問發(fā)射限制。1級激光輻射水平不視為危險。連接器就位后，所有激光輻射都留在光纖內(nèi)。離開光纖的最大輻射功率（正常條件下）為-12.6 dBm或55 x 10-6瓦。從收發(fā)器上卸下光學連接器可使激光輻射直接從光學端口發(fā)出。光學端口的最大輻射（在最壞情況下）為0.8 W cm-2或8 x 103 W m2 sr-1。請勿使用光學儀器查看激光輸出。使用光學儀器觀察激光輸出會增加眼睛的危險。查看輸出光端口時，必須斷開網(wǎng)絡適配器的電源
