High Reliability Polarization Beam Combiner
For PM combining of wavelengths between 915–1600 nm, where the costs of component replacement are prohibitive.
Full Product Description- Operating wavelength:
- 975 nm, 1550 nm ¹ ² ⁷
- Optical power handling:
- Max: 4 W ⁵ ⁶
Product description
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.
Key features
- High polarization extinction ratio (PER)
- High Power Handling
