Description
-5°C to +55°C (23°F to 131°F) at an altitude of 0-1800 m
(0-5906 ft.)
NOTE
When the altitude is 1800-5000 m (5906-16404 ft.), the highest
operating temperature reduces by 1°C (1.8°F) every time the
altitude increases by 220 m (722 ft.).
The equipment can operate beyond the normal operating
temperature range for a short-term period, but the following
conditions must be met:
● The equipment operates at a temperature of over 45°C (113°F)
consecutively for at most 96 hours in one year.
● The equipment operates at a temperature of over 45°C (113°F)
for a total of no more than 360 hours in one year.
● The equipment operates at a temperature of over 45°C (113°F)
for no more in 15 times in one year.
The equipment may be damaged or experience unexpected
exceptions if any of the preceding limits is exceeded.
The equipment cannot start when the temperature is lower than 0°C
(32°F). The maximum distance of optical modules used in these
conditions cannot exceed 10 km.
