Optical Limiters
Kilolambda Ltd
Optical Power Limiter regulates the optical power. You can use it at the input to power-sensitive equipment, at the output of high power components, such as amplifiers, or wherever power regulation is required.
Optical specifications:
- Limit power: Selectable from 6dB to 17dB
- Limit power accuracy: ±0.5 dB
- Max. operating CW power: 7dB above Plimit (typical)
- Sustainable power: 10 dB above Plimit (typical)
- Wavelength range: C+L (850-1650 nm, per request)
- Polarization dependent loss: <0.1dB
- Response time: 100 µsec (typical)
- Insertion loss: 1.5dB typical
- Return loss: >40dB Limit power: Selectable from 6dB to 17dB
