Fiber Optic Splice Closure Performance

- Jan 18, 2018 -

1. Suitable ambient temperature: -45 ℃ ~ 55 ℃

2. Atmospheric pressure: 70KPa ~ 106KPa

3. Sealed at room temperature: internal pressure 70 KPa,  and pressure does not decline in 72 hours.

4. Temperature cycle: room temperature 20 ℃, residence time of high and low temperature (-40 ℃ ~ 60 ℃) not less than 3 hours, 12 hours a cycle, the internal pressure of 60 KPa ± 5 KPa for 10 times, the pressure drop does not exceed 5 KPa, then immersed in stable of water at room temperature for 15 seconds observation, no bubbles escape.

5. Withstand voltage: Entering the 15KV DC  through metal, metal and earth for 2 minutes ,without breakdown and no arcing phenomenon.

6. Insulation resistance: After the cable is sealed, the insulation resistance between the metal parts and between the metal and the ground is more than 105MΩ.

7. Additional loss: fiber in the storage coil with no additional wear and tear.

8. Life: Fiber optic splice closures material life is more than 20 years.
