The Phoenix Photonics range of fused fiber couplers has been developed
to offer the designer flexibility in optimizing system performance. The
proven FBT technology base has been utilized to optimize specific device
parameters, reflected in the specific product categorization. The polarization
maintaining couplers give good loss performance whilst preserving the
integrity of the input on-axis polarization state. All of the coupler options offer very low excess loss, good polarization isolation, and are available in a range of coupling ratios from 1% to 50% and have 1x2 or 2x2 configuration.. |

Notes: 1. Center wavelength can be tailored to customer requirements 2. Polarization isolation also termed extinction ratio is the measure of the ability of the coupler to maintain the linear state of polarization launched on to the slow axis of the coupler. 3. All specifications are for polarization state on the slow axis and measured @ 250C 4. Specifications on this product are being developed further and may change, please ensure that this is the latest edition available from the website. |
