Ultra-low ratio tap coupler
For tapping low power from a fiber signal path, for wavelengths between 700–1600 nm.
Full Product Description- Wavelength:
- 700–1599 nm
Product description
The all-fiber construction and excellent loss characteristics provide exceptional reliability at high powers, for applications such as fiber lasers. Low tap ratios such as 0.1%, 0.01%, or 0.001% enable the monitoring photodetector to operate without damage or saturation.
G&H's proprietary manufacturing technology provides ultra-low loss in the signal path, thereby maximizing optical power handling. Consistently high return loss (>55 dB) reduces the amount of optical power reflected back along the input fiber, which helps fiber lasers operate in a stable manner.
