Specifications

1.ER 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.

2.ER will be 2 dB lower for Nufern FUD-3460 fiber and Nufern PM 1950.

3.RL is 5 dB lower, ER is 2 dB lower for each connector added. Connector key is aligned to slow axis.

4.The Optical Power is 1 W only for connector added. For visible wavelength, the limit is 50 mW.

5.Data tested at central wavelength only.
