Operating Wavelength: 1310 nm ± 20 nm
Isolation (2 - 1 ): > 35 dB
Isolation ( 3 - 2): > 32 dB
Insertion Loss ( 1 - 2 ): 0.9 - 1.3 dB
Insertion Loss ( 2 - 3 ): 0.9 - 1.3 dB
Crosstalk ( 1 - 3 , 3 - 1 ): > 40 dB
Return Loss: < 55 dB
PDL: < 0.1 dB
PMD: < 0.1 ps
Epoxy-Free Beam Path 1 - 2
Power Handling (1 - 2 ): 5 W
Power Handling (2 - 3 ): 500 mW

 


 

Polarization Independent (SM) Fiber Circulator
