Angular displacement and SOP speeds in aerial and buried single mode and polarisation maintaining fibers

Optical fiber transmission suffers significant penalty from dispersion related effects. In this study, we experimentally investigate angular displacement and speed of state of polarization in single mode fibers (SMF) and polarization maintaining fibers in two states, i.e. aerial and buried state. The results show that a buried single mode fiber incurs minimal change of state of polarization (implying lower polarization mode dispersion) as compared to a buried polarization maintaining fiber, with a slight difference of 0.000464 standard deviation (spread). This is a good finding, since, most of the telecom companies use single mode fibers for their transmission, so reinstallation might be so costly, time wasting and unnecessary as well as the costs that would be incurred in purchasing PMF which are more expensive compared to the single mode fiber, as per 'THORLABS'. i.e $33.75-$40.0 per meter of PMF compared to $7.0-$14.0 per meter of a single mode fiber. However in cases where aerial transmissions are un-avoidable, Polarization maintaining fibers are highly recommended as compared to single mode fibers.
