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.

More Detail

Routing path is from port 1, 2 to 3, Here are three options of polarized state from Port 1, 2 to Port 3:

Option 1, PM to SM,

Port 1: 50%,Linear polarized light in, through slow axis, Port 2: 50%,Linear polarized light in, through slow axis

Port 3, 100%, Circularly polarized light Out,

Option 2: PM to PM, port 1 is slow axis 0° aligned to port 3

Port 1, 2, only work through slow axis, blocked the fast,

The slow axis of port 1 is aligned to the slow axis of port 3,

The slow axis of port 2 is aligned to the fast axis of port 3,

Option 3:PM to PM, port 1 is slow axis 45° aligned to port 3

Port 1, 2, only work through slow axis, blocked the fast,

Port 1 or 2, 100%,Linear polarized light in, through slow axis,

Port 3, 25% linear polarized light out, through slow axis, and 25% by the fast,
