1类激光收发器
单模接口模块使用1类激光收发器。
安装或操作这些模块前，请阅读以下安全信息。
1类激光收发器使用光学反馈回路来维持1类操作限制。该控制回路消除了
需要进行维护检查或调整。输出为出厂设置，不允许用户进行任何调整。
1类激光器收发器符合以下安全标准：
•21 CFR 1040.10和1040.11美国卫生与公众服务部（FDA）。
•IEC出版物825（国际电工委员会）。
•CENELEC EN 60825（欧洲电工标准化委员会）。
当在其性能限制范围内运行时，激光收发器输出满足所有设备的1级可访问发射限制
三个标准。1级激光辐射水平不被视为危险。
当连接器就位时，所有激光辐射都留在光纤内。辐射功率的最大输出量
光纤（在正常条件下）为-12.6 dBm或55 x 10-6瓦。
从收发器上卸下光学连接器可使激光辐射直接从光学端口发射。最大
来自光学端口的辐射（在最坏情况下）为0.8 W cm-2或8 x 103 W m2 sr-1。
请勿使用光学仪器查看激光输出。使用光学仪器查看激光输出可提高视力
危险查看输出光端口时，必须断开网络适配器的电源。
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.
