*Above specifications are for devices without the connectors.
*For device with connector, IL is 0.3dB higher, RL is 5dB lower, ER is 2dB lower. The default connector key is aligned to slow axis.
Biaxial work
Port1 is the incoming optical end, Port2 is the small spectral ratio, and Port3 is the large spectral ratio.
Port3 is the incoming optical end, Port4 is the small spectral ratio, and Port1 is the large spectral ratio.
Slow axis work, fast axis cut-off
Port1 is the incoming optical end, Port4 is the small spectral ratio, and Port3 is the large spectral ratio.
Port3 is the incoming optical end, Port2 is the small spectral ratio, and Port1 is the large spectral ratio.
