Remarks:

Detail requirements need to be sent to us for cable design and price calculation. Below requirements are a must:

A, Power transmission line voltage level
B, fiber count
C, Cable structure drawing & diameter
D, Tensile strength
F, Short circuit capacity

Type test

Type test may be waived by submitting maker’s certificate of the similar product performed in an internationally acknowledged independent test organization or laboratory. If type test should be performed, it will be carried out according to an extra type test procedure reached to an agreement between purchaser and manufacturer.

Routine test

The optical attenuation coefficient on all production cable lengths is measured according to IEC 60793-1-C1C (Back-scattering technique, OTDR). Standard single-mode fibers are measured at 1310nm and at 1550nm. Non-zero dispersion shifted single–mode (NZDS) fibers are measured at 1550nm.

Factory test

Factory acceptance test is carried out on two samples per order in the presence of the customer or his representative. The requirements for quality characteristics are determined by relevant standards and agreed quality plans.
