Packing & Shipping
Cable is supplied in lengths as specified in PI or as requirement. Each length will be shipped on a separate non-returnable wooden drum. The minimum barrel diameter of the drum will not be less than 30 times the cable diameter.
The cable on each reel will be completely covered with a thermal wrap which is fastened to the cable by packaging straps. This wrap is reusable and provides excellent thermal and UV protection.
The cable ends will be sealed with plastic protection caps to prevent water penetration. The ends will be easily accessible for testing. A final inspection test report with attenuation performance data for each fiber is attached inside the drum.
