G&H proprietary manufacturing technology provides uniquely low excess loss, along with low polarization and temperature dependence for all ports.
These fused couplers are available in a wide range of tap ratios, wavelength ranges, housing, and connector options, and can be readily specified in a wide variety of applications, enabling rapid design cycles and new project builds. Reliability is assured through qualification to Telcordia GR-1221, with a field-proven FIT rate of <1.
- Ultra-low pump loss
- Minimum wastage of pump power
- High EDFA output power
- 960 nm and 1060 nm are also available
- < 1 FITs
