The LD-PD'S PL-PMI Series is Polarization Maintaining Isolator. This is one High power fiber optic components we special design for RGB fiber laser. And now wavelength at 405/532/633/780nm is available, This Unit Can handle maximum average power at 1w. We can help Customize according to Customer's Requirements.

Tsub=25°C, CW bias unless stated otherwise

Note: 

1.*IL is 0.5 dB higher, RL is 5 dB lower, and ER is 2 dB lower for each connector added. 

2.*Connector key is aligned to slow axis.
