Long-term operating temperature [°C(°F)]

-5°C to +45°C (23°F to 113°F) at an altitude of 0-1800 m (0-5906 ft.)

Short-term operating temperature [°C(°F)]

Not supported

Storage temperature [°C(°F)]

–40°C to +70°C (–40°F to +158°F)

Restriction on the operating temperature variation rate

When the altitude is 1800-5000 m (5905.44-16404 ft.), the highest operating temperature reduces by 1°C (1.8°F) every time the altitude increases by 220 m (721.78 ft.).

The device cannot start when the temperature is lower than 0°C (32°F). 

The operating temperature of a device ranges from -5°C to +45°C (23°F to 113°F)) when the device uses the following optical modules:

- GE optical modules with a transmission distance of less than or equal to 10 km
