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

-5°C to +50°C (23°F to 122°F) (0 m to 1800 m altitude, non-industrial optical modules)

-5°C to +55°C (23°F to 131°F) (0 m to 1800 m altitude, industrial optical modules with transmission distances less than or equal to 10 km)

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

Not supported

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 switch cannot be started when the ambient temperature is lower than 0°C (32°F).

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.
