Using our proven fused biconical taper process, our HI REL capability is built upon the foundation of the long-established manufacturing history of very reliable terrestrial components.
The ultra-low loss of our fused fiber components helps to promote low noise and improved system margin in undersea transmission systems.
Full facilities are available to perform customer-specific HI REL qualification programs, which can consist of accelerated aging and Weibull analysis. Our design standard is 0.1 FITs, meaning failure-free operation for one billion field hours.
Manufacturing is carried out on specially-developed workstations, and advanced fiber management, in-process screening, and customer-specific validation tests are implemented, to further enhance component reliability. Components are supplied in regular or custom housings, depending upon the installation environment.
- High polarization extinction ratio (PER)
- High Power Handling
