The optical time-domain reflectometer (OTDR) is the core equipment, used to measure fiber link attenuation, length, and locate faults; a combination of light source and optical power meter is used for precise measurement of insertion loss; an optical fiber geometry tester.

Packaging and Labeling Inspection:Check if the outer packaging is intact, without damage, moisture, or deformation., cable model, length, production date, manufacturer name) against the order documents. Documentation Review:Ensure completeness of certificates, factory. Optical fibre cables are widely used in telecommunications, data centers, and industrial networks. Their mechanical performance directly determines installation reliability and long-term service stability—mechanical tests verify resistance to external stresses (tension, bending, compression, etc. ). This test method applies to optical fibre cables which are tested at a particular tensile strength in order to examine the behaviour of the attenuation and/or the fibre elongation strain as a function of the load on a cable which may occur during installation and operation. It explains the roles of major standards organizations, key optical performance parameters, mechanical and appearance. The tensile test, which is conducted on optical fiber cable is one of the major tests and all customers prefer to conduct this test either as a witness test or as a type test and in some cases as both. Rigorous testing standards such as IEEE Std. 60794-1-2 have been developed by international standards.
