New! F-SPF (820 nm) and F-SPV (633 nm) Bow-tie fibers are now available with standard Patchcords! Please note that F-PM1300 is obsolete and F-PM1550 is a recommended replacement.The Fibercore Bow-tie polarization maintaining (PM) fibers, also known as highly birefringent (HiBi) fibers, are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 1310/1550 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. For custom options please contact a Newport Applications Engineer.
