| Long-term operating temperature [°C(°F)] | –5°C to +45°C (23°F to 113°F) at an altitude of 0 to 1800 m (0 to 5905.44 ft.) |
| Short-term operating temperature [°C(°F)] | -5°C to +50°C (23°F to 122°F) at an altitude of 0-1800 m (0-5905.44 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 device can work for a short period of time when the operating temperature is beyond the normal range, but the following conditions must be met:
If any of the preceding conditions is not met, the device may be damaged or an unknown error may occur. Devices 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. The operating temperature is –5°C to +40°C (23°F to 104°F) when 100GE optical modules with a transmission distance of 10 km or longer are used. |
