Phoenix Photonics in-line polarization maintaining optical fiber power monitors replace the tap coupler – photodiode with a single small footprint package. The device is based on interaction with the evanescent field of the propagating signal and consequently is non-invasive to the optical path. This technology offers low insertion loss with high responsivity.

Notes to Specifications
1. Responsivity is specified at the lowest wavelength in the specified operational bandwidth and increases with increase in wavelength. Alternative responsivity can be accommodated.
2. The effective tap ratio enables a direct comparison with the tap coupler/photodetector alternative.
3. The maximum operational power is defined by the saturation power reaching the photodiode, alternative tap ratios can be provided to accommodate higher or lower power systems.
3.
Insertion loss is worst case over the full specification range without connectors.
4. The power monitors are available over the full operational range, however the quoted specifications are applicable to the following bands:
13 – 1280nm to 1330nm
14 – 1450 nm to 1530nm
15 – 1530nm to 1610nm
For requirements outside these bands please contact our sales team.
5. The power monitor preserves the on-axis linear input polarization state to better than 25dB.
