Note: 1. If tap port coupling ratio is ≤ 5%, ER will be 2dB lower; for ≤1% tap port, ER is out of concern
2. The specifications are connector excluded.
3. For devices with connectors, 0.3dB (PC)/0.4 dB (APC) higher for IL, 5dB lower for RL and 2dB lower for ER.
4. For device with connector, key aligned to slow axis if no advance requirement.
