The Fibercore Bow-tie polarization maintaining (PM) fibers, also known as highly birefringent (HiBi) fibers, are optimized for operation at 488/514, 633, 820 and 1300/1550 nm wavelengths and have a beat-length of less than 2 mm. The beat-length, the length over which the fiber polarization rotates through 360°, is one of the fundamental performance measures: the shorter the beat-length, the better the polarization-preserving properties of the fiber. The F-SPPC-13 and F-SPPC-15 fibers are polarization preserving fibers specifically made to be compatible with standard telecom fibers and PANDA™ PM fibers. Splicing these fibers to PANDA™ fibers routinely results in a splicing loss of <0.2 dB and an excellent extinction ratio of -32 dB.
Corning's PANDA™ polarization maintaining fibers offer low attenuation and excellent birefringence for high performance applications. The operating wavelengths range from 400-1500 nm with beat lengths ranging from less than 1.7mm to 5mm. Both the Bow-tie and the PANDA™ PM fiber have a step index profile. Also available are standard FC/APC PM patchcords, whose slow axis is accurately aligned to the connector key. In addition Newport provides custom patch cords with any available termination type at either end.
