OFS Polarization-Maintaining Dispersion Compensating Optical Fiber (PM-DCF) provides compensation of not only dispersion, but also dispersion slope, of standard PM fiber (e.g. TruePhase® 1550). OFS PM-DCF is a stress rod supported DCF leveraging the advances over many years in the design of standard telecommunication DCFs. By combining standard PM fiber with PM-DCF a dispersion managed PM link can be build, providing a transmission media for sub picosecond pulses without any pulse broadening. A PM dispersion managed link eliminates the impairment from both chromatic dispersion and polarization mode dispersion (PMD).
