1類(lèi)激光收發(fā)器
單模接口模塊使用1類(lèi)激光收發(fā)器。
安裝或操作這些模塊前，請(qǐng)閱讀以下安全信息。
1類(lèi)激光收發(fā)器使用光學(xué)反饋回路來(lái)維持1類(lèi)操作限制。該控制回路消除了
需要進(jìn)行維護(hù)檢查或調(diào)整。輸出為出廠設(shè)置，不允許用戶(hù)進(jìn)行任何調(diào)整。
1類(lèi)激光器收發(fā)器符合以下安全標(biāo)準(zhǔn)：
?21 CFR 1040.10和1040.11美國(guó)衛(wèi)生與公眾服務(wù)部（FDA）。
?IEC出版物825（國(guó)際電工委員會(huì)）。
?CENELEC EN 60825（歐洲電工標(biāo)準(zhǔn)化委員會(huì)）。
當(dāng)在其性能限制范圍內(nèi)運(yùn)行時(shí)，激光收發(fā)器輸出滿(mǎn)足所有設(shè)備的1級(jí)可訪問(wèn)發(fā)射限制
三個(gè)標(biāo)準(zhǔn)。1級(jí)激光輻射水平不被視為危險(xiǎn)。
當(dāng)連接器就位時(shí)，所有激光輻射都留在光纖內(nèi)。輻射功率的最大輸出量
光纖（在正常條件下）為-12.6 dBm或55 x 10-6瓦。
從收發(fā)器上卸下光學(xué)連接器可使激光輻射直接從光學(xué)端口發(fā)射。最大
來(lái)自光學(xué)端口的輻射（在最壞情況下）為0.8 W cm-2或8 x 103 W m2 sr-1。
請(qǐng)勿使用光學(xué)儀器查看激光輸出。使用光學(xué)儀器查看激光輸出可提高視力
危險(xiǎn)查看輸出光端口時(shí)，必須斷開(kāi)網(wǎng)絡(luò)適配器的電源。
Safety Information
Class 1 Laser Transceivers
The single mode interface modules use Class 1 laser transceivers.
Read the following safety information before installing or operating these modules.
The Class 1 laser transceivers use an optical feedback loop to maintain Class 1 operation limits. This control loop eliminates the
need for maintenance checks or adjustments. The output is factory set, and does not allow any user adjustment. Class 1 Laser
transceivers comply with the following safety standards:
? 21 CFR 1040.10 and 1040.11 U.S. Department of Health and Human Services (FDA).
? IEC Publication 825 (International Electrotechnical Commission).
? CENELEC EN 60825 (European Committee for Electrotechnical Standardization).
When operating within their performance limitations, laser transceiver output meets the Class 1 accessible emission limit of all
three standards. Class 1 levels of laser radiation are not considered hazardous.
When the connector is in place, all laser radiation remains within the fiber. The maximum amount of radiant power exiting the
fiber (under normal conditions) is ‐12.6 dBm or 55 x 10‐6 watts.
Removing the optical connector from the transceiver allows laser radiation to emit directly from the optical port. The maximum
radiance from the optical port (under worst case conditions) is 0.8 W cm‐2 or 8 x 103 W m2 sr‐1.
Do not use optical instruments to view the laser output. The use of optical instruments to view laser output increases eye
hazard. When viewing the output optical port, power must be removed from the network adapter.
