The antenna should be located in an area that is inaccessible to the public where the RF radiation exceeds the stipulated value.
l
Before entering the area where RF radiation exceeds the stipulated value, the staff should know the location of the area and shut down the transmitters. Such an area may not exist; but if it exists, the area must be within a range of less than 10 m around the antennas.
l
Each forbidden area should be indicated by a physical barrier and striking sign to warn the public or staff.
Laser
CAUTION When handling optical fibers, do not stand close to, or look into the optical fiber outlet with unaided eyes. Laser transceivers or transmitters are used in the optical transmission system and associated test tools. Because the laser that is transmitted through the optical fiber produces a small beam of light, it has a very high power density and is invisible to human eyes. If a beam of light enters the eye, the retina may be damaged. Normally, staring into the end of an unterminated optical fiber or broken optical fiber with the unaided eyes from a distance of more than 150 mm [5.91 in.] will not cause eye injury. Eyes may, however, be damaged if an optical tool such as a microscope, magnifying glass or eye loupe is used to stare into the bare optical fiber end. Read the following guidelines to prevent laser radiation: l
Only the trained and authorized personnel can perform the operation.
l
Wear a pair of eye-protective glasses when you are handling lasers or optical fibers.
l
Ensure that the optical source is switched off before disconnecting optical fiber connectors.
l
Never look into the end of an exposed optical fiber or an open connector if you cannot ensure that the optical source is switched off.
l
To ensure that the optical source is switched off, use an optical power meter.
l
Before opening the front door of an optical transmission system, ensure that you are not exposed to laser radiation.
l
Never use an optical tool such as a microscope, a magnifying glass, or an eye loupe to look into the optical fiber connector or end.
Read the following instructions before handling optical fibers:
1-8
l
Only the trained personnel can cut and splice optical fibers.
l
Before cutting or splicing an optical fiber, ensure that the optical fiber is disconnected from the optical source. After disconnecting the optical fiber, use protecting caps to protect all the optical connectors. Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd
