Long-term operating temperature [°C(°F)] |
-5°C to 50°C (23°F to 122°F) at an altitude of 0-1800 m (0-5906 ft.) |
|
Short-term operating temperature [°C(°F)] |
-5°C to 55°C (23°F to 131°F) at an altitude of 0-1800 m (0-5906 ft.) |
|
Restriction on the operating temperature variation rate [°C(°F)] |
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 operating temperature ranges from -5°C to 45°C (23°F to 113°F) when optical modules with transmission distances greater than or equal to 70 km are used. 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 50°C (122°F) consecutively for at most 96 hours in one year. · The equipment operates at a temperature of over 50°C (122°F) for a total of no more than 360 hours in one year. · The equipment operates at a temperature of over 50°C (122°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. |
