- Above specifications are for device without connector.
- For devices with connectors, IL will be 0.3dB higher, RL will be 5dB lower. Power transmits through the connector less than 2W.
- If there is pulse application, please be sure to inform us of pulse energy and peak power.
Package Dimension
PS: For forward pump, signal wavelength is polarization independent. For backward pump, signal wavelength is Polarization dependent.
