Testing and Inspection

The optical properties of all fibers are measured prior to cable manufacturing and remain traceable throughout the manufacturing process and the lifetime of the cable.
After cabling, we use statistical process control techniques along with periodic verification to insure 100% compliance to attenuation requirements in each length of cable with bi-directional OTDR at all operating wavelengths. Cable dimensional measurements are also made at final inspection and recorded.

 

Packing and 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.
