| 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. ²ER will be 2 dB lower for Nufern FUD-3460 fiber and Nufern PM 1950. ³RL is 5 dB lower, ER is 2 dB lower for each connector added. Connector key is aligned to slow axis. ⁴The Optical Power is 1 W only for connector added. For visible wavelength, the limit is 50 mW. ⁵Data tested at central wavelength only. | ||
