Note: 1. Customization is available. The connector default slow axis alignment key
2. 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.
3. For >10W high power applications, we will use heat sink package
4. If there is pulse application, please be sure to inform us of pulse energy and peak power.
