Compensation of Polarization Mode Dispersion
The topic of thesis is “Compensation of Polarization Mode Dispersion (PMD)” in Fiber optics communication and its impact on high speed data transmission. The work can be divided into three parts which deals with major aspects of PMD: characteristics, transmission and compensation. Polarization-mode dispersion (PMD), in single-mode optical fibers, is a phenomenon that a limit the bit-rate-distan...
متن کاملSimultaneous chromatic dispersion and PMD compensation by using coded-OFDM and girth-10 LDPC codes.
Low-density parity-check (LDPC)-coded orthogonal frequency division multiplexing (OFDM) is studied as an efficient coded modulation scheme suitable for simultaneous chromatic dispersion and polarization mode dispersion (PMD) compensation. We show that, for aggregate rate of 10 Gb/s, accumulated dispersion over 6500 km of SMF and differential group delay of 100 ps can be simultaneously compensat...
متن کاملPeriodic compensation of polarization mode dispersion
Polarization mode dispersion is the effect of signal broadening in a fiber with birefringent disorder. The disorder, frozen into the fiber, is characterized by the so-called vector of birefringence (VB). In a linear medium a pulse broadens as the two principal states of polarization split. It is well-known that, under the action of short-correlated disorder, naturally present in fibers, the dis...
متن کاملJoint compensation of CD and PMD in direct-detected OFDM transmission using polarization-time coding.
We propose and demonstrate a polarization-time coding (PTC) method which can effectively compensate both the CD and first order PMD in direct-detected OFDM transmission. Compared with the previous methods, the proposed PTC not only alleviates the need for the complex dynamic polarization controller but also exhibits superior transparencies to both the OFDM format and transmission data rate. For...
متن کاملPackage for fiber Bragg gratings (FBG) and a comparative study on their polarization mode dispersion (PMD) at varying temperature
A temperature-compensated material of fiber Bragg grating (FBG), which has negative thermal -expansion coefficient has been presented. The temperature coefficient of FBGs’ center wavelength is less than 0.0005 nm/°C after three-layer-structure temperature-compensated package under tension. For the first time, PMD of FBG with and without temperature compensation has been detailedly studied and m...
