PM Filter Coupler
SENKO’s Polarization Maintaining Filter Coupler series is manufactured using advanced technology to allow the input signal to be split into various ratios with high extinction ratio.
- Low Insertion Loss
- High Return Loss

Notes:
1. Above specifications are for devices without the connectors.
2. For devices with connectors, IL will be 0.3dB higher, RL will be 5dB lower, and ER will be 2dB lower.
3. The PM fiber and the connector key are aligned to the slow axis. And for F type, fast axis is blocked.
