We provide 19 years of experience and excellent solutions for your hardware needs in both ADSS (All-Dielectric Self Supporting), OPGW (Optical Ground Wire), and other cable calmps. Such as suspension clamp, dead-end clamp, dead-end fittings, joint box, etc. We are fully equipped to serve as your hardware provider and be your “one-stop-shopping” service. Or, if you prefer, you may purchase the approved hard w a re separately.

Hunangl ensures a continuing level of quality in our cable products through several quality control programs including ISO 9001. We ensure the product reliability through rigorous qualification testing of each product family.Both initial and periodic qualification testing are performed to assure the cableʼs performance and durability in the field environments.

GENERAL
There are different test series to assure the quality of OPGW:
- Routine test (in‒process testing according to internal quality plan)
- Factory acceptance test (FAT, witnessed by customer)
- Type test (only in case of a basic new design, repetition in exceptional cases)
OPGW tests shall be in accordance with applicable standards or agreements between purchaser and manufacturer.
As a general rule the tests will be performed according IEC 60794-4-10.However, if necessary tests can be done according to IEEE Std1138.

Type test
Type test may be waived by submitting makerʼs 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-CIC (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.
