The Pm-1550 has a strong form-birefringence and is optimized to create a short beat length between the polarizations.
Furthermore it has reduced bend-induced coupling between polarization states, an improved polarization extinction ratio, and is 30 times less temperature sensitive than conventional Hi-Bi fiber.
・Low loss fiber from 600 to 1700 nm
・SIngle mode at all wavelengths
・Polarization Maintaining
・Radiation hard pure silica fiber
・Wavelength independent MFD
