Optical Fiber Performance and Reliability Assessment

We can assess fiber-optic products for performance and reliability to many published industry standards, such as the Telcordia GR-series standards, international fiber-optic performance standards and to your specifications.

Optical fiber cords connected to hardware


Telecommunications and network systems are increasingly making the switch to optical fiber. In response, our fiber optics program has been expanded and enhanced to meet growing industry needs. We have significantly increased our capacity and capability to carry out safety and transmission performance testing on multiple fiber-optic products.


You can satisfy all of your safety certification and performance Verification needs for optical fiber products in a single submittal. We offer bundled safety certification and performance Verification service packages that allow you to combine the applicable UL, network equipment-building system (NEBS) and electromagnetic compatibility (EMC) testing services, saving time and money by eliminating redundant testing.

Our comprehensive follow-up program helps simplify supply chain management by determining products’ continued compliance with industry standards.

Why UL
