¹ER data listed in the table are for the ports with coupling ratio greater than 10%. It will be 2 dB lower for a tap port with coupling ratio between 1 - 10%. For 1% tap port, ER is not considered.
²IL is 0.3dB higher, RL is 5 dB lower, ER is 2 dB lower for each connector added. Connector key is aligned to slow axis.
³The Optical Power is 1 W only for connector added.
⁴Data tested at central wavelength only.
