Polarization Independent (SM) Fiber Circulator This is the default circulator configuration with the 1 - 2 path the HP leg. This is typically used when you have a high input power and a low return signal.
OC-3-780, OC-3-800, OC-3-830 or OC-3-850
Operating Wavelength:
Center wavelength ± 10nm
Isolation (2 - 1 ):
27 - 35 dB
Isolation ( 3 - 2):
27 - 35 dB
Insertion Loss ( 1 - 2 ):
0.8 - 1.8 dB (1.2 typical)
Insertion Loss ( 2 - 3 ):
1.3 - 2.0 dB (1.8 typical)
PDL:
< 0.3 dB
Crosstalk ( 1 - 3 , 3 - 1 ):
< 40 dB
Return Loss:
> 48 dB
Power Handling (1 - 2 ):
1 W
Power Handling (2 - 3 ):
300mW
High power channel can be specified as 1 - 2 or 2 - 3. inquire.
Polarization Dependent (PM) Fiber Circulator Polarization dependent circulator using PM fiber on all ports. High power on both legs (1 - 2 and 2 - 3). When connectorized the slow axis of the PM fiber is aligned to the connector key.
OC-3-780-PM, OC-3-800-PM, OC-3-830-PM or OC-3-850-PM
