3.2.1 Temperature/Humidity Requirements
To ensure the normal operation and service life of a switch, you need to maintain the temperature and the humidity of the
equipment room at a certain level. If the humidity level in the equipment room is too high for a long time, it will lead to bad
insulation of the insulating material or even leakage. Sometimes, the mechanical performance, change of material and the
corrosion of some metal parts are also likely to occur. If the relative humidity is too low, the captive screw may become loose
due to the shrinking of insulating sheath. Meanwhile, the static electricity is likely to be produced in the dry weather, which may
jeopardize the CMOS circuit of the switch. The Higher the temperature is, the greater the damage to the switch will be. The
reliability of the switch will be then seriously affected and its service span will be shortened because of exposure to
high-temperature environment for a long term. The ultra-high temperature will speed up the aging process of the insulating
material.
3.2.2 Laser Safety
In operating status, it is prohibited to stare into the open optical interface because the laser being transmitted through the
optical fiber will produces a small beam of light, it has very high power density and is invisible to human eyes, when a beam of
light enters the eye, retinal may be burned.
