900um-buffer fiber with one SC/PC connector on port 1. Comparing with similar-model and new-model datasheet at the 2 pdf links below, we very believe this circulator is for both C-band and L-band. These circulators come with C-band circulators P/N:CIR10BN39S (Store product code: OFC-CIR-009F) together, they both come with only one SC/PC connector on port 1. So we believe these two models are very similar. We have tested one sample, P1-P2 loss (port 1 to port 2): 0.69dB at 1550nm, 0.79dB at 1590nm, P2-P3 loss is 0.62dB at 1550nm, 0.86dB at 1590nm. The tested loss includes one connector loss which would be about 0.2dB. -

Type A. With 3 Panda PMF connectors, connector key is aligned to slow axis. With 900um loose-tube fibers, 1-meter long. New released products, we ordered directly from manufacturer.
The Polarization Maintaining Optical Circulator is a compact high performance light wave component that routes incoming signals from Port 1 to Port 2, and incoming Port 2 signals to Port 3. The component provides high isolation, low insertion loss, high extinction ratio, and excellent environment stability.
Operating Wavelength Range: ±30 nm.

6-port circulator. For 1.55um wavelength windoow. With 6 FC/PC connectors on all 6 ports, ready to use in your lab experiment. 1-meter 9/125/900umm SMF-28 fibers on all 6 ports. You can connect five FBG (or DCM) at port 2 to port 5 respectively, so you do not have to use five 3-port circulators for the same function. The insertion loss from port 5 to 6 is a littler higher but it still meets specification <1.0dB after deducting fiber connector loss. -
