Note:
1.Above specifications are for device without connector, If with connector, IL will be 0.3dB higher, return loss with be reduce 5dB and Extinction Ratio will reduce 2dB.
2. For >10W high power applications, we will use heat sink package
3. If there is pulse application, please be sure to inform us of pulse energy and peak power.
