Quality Control Of Outdoor Fiber Optical Cable
1. Attenuation Testing By OTDR
The cable and fiber attenuation will be tested during each steps of cabling from bear fibers , loose tube twisting to cabling according to the IEC 60793 standard . The attenuation of 1310 nm ≤ 0.36db/km and 1550 nm ≤ 0.22db/km, and the cable length will be tested as well .
2. Water Penetration Testing
The cable will be tested the water penetration performance . IEC standard requests the 1m length cable no water leakage from outside within 24 hours .
3.High And Low Temperature Cycling Testing
Time of testing:
Transition from 0°C to -40°C:2hours;
Time per each durationat-40°C:8 hours;
Transition from-40°C to +85 °C;4hours;
duration at +85°C:8hours;
Transition from +85°C to 0°C:2hours
Standard Of IEC 60794:
Attenuation variation for reference value (the attenuation to be measured before testat+20±3°C) w 0.05 dB/km
4.Repeated Bending Testing
5. Cable Bending And Torsion Testing60794 Standard
No additional attenuation ≤ 0.05db/km and no damage to outer jacket and inner elements in addition of 2m sample length and ± 180 degrees .
6. Optical Cable Vibration Testing
The cable and fiber comprehensive performance should be stable during vibration 10 mins in 50HZ frequency .
7. Cable tensile strength testing
The fiber attenuation should stay in safe range during pulling cable by specific tension strength of different cables .
