Opis:: Experiments and theoretical analysis of influence of temperature on polarization mode dispersion (PMD) in single mode optical fibers and cables are presented. Forces generated by contracting buffer create optical birefringence and increase fiber PMD at low temperatures. Single mode fiber (SMF) in 0.9 mm polymeric tight-buffer can exhibit an extra component of PMD exceeding 0.3 ps/?km in such conditions. On the other hand, tight-buffered spun nonzero dispersion-shifted fibers (NZDSF) and optical units with stranded single mode fibers have showed good stability of PMD over wide range of temperatures. This is due to presence of circular strain in the core, blocking accumulation of mechanically induced birefringence.

Tytuł:: Influence of temperature and aging on polarization mode dispersion of tight-buffered optical fibers and cables

Opis:: This paper presents results of laboratory tests investigating influence of temperature on polarization mode dispersion (PMD) in variety of single mode optical fibers and cables. Research was focused primarily on tight-buffered fibers, where most pronounced effects resulting from buffer shrinkage or expansion were expected. The goal was to verify performance of optical fiber cable exposed to extreme temperatures and to compare behavior of different cables. Very strong temperature dependence of PMD was detected in standard single mode fibers with 0.9 mm tight buffer, commonly used in indoor cables, and in complete cable with such fiber. However, both nonzero dispersion-shifted fibers, spun during drawing and optical unit used in optical ground wire (OPGW), where 12 fibers are stranded showed good stability of PMD during thermal cycling. The same optical unit extracted from OPGW exhibited excellent PMD stability also during accelerated life test.

Tytuł:: Fusion Splicing and Testing of Photonic Crystal Fibers
Autorzy:: Borzycki, K.
Powiązania:: https://bibliotekanauki.pl/articles/308962.pdf
Data publikacji:: 2009
Wydawca:: Instytut Łączności - Państwowy Instytut Badawczy
Tematy:: fusion splicing

Opis:: Properties of two different photonic crystal fibers (PCF) were characterized, enabling comparisons. Properties investigated included spectral attenuation, polarization mode dispersion (PMD), optical time domain reflectometer characteristics, elastooptic factor describing transmission delay induced by axial strain plus effects of temperature cycling and fiber twist on PMD and loss. In particular, temperature and twist dependence of PMD was different for each fiber tested. For optical measurements, fibers were fusion spliced to pigtails with standard telecom single mode fibers. PCF splicing procedures and solutions adopted to minimize collapse of holes during arc fusion and splice loss are presented. It was found that fusion splicing procedure must be individually tailored to each combination of fibers.

Tytuł:: Testing of highly doped and photonic crystal optical fibers
Autorzy:: Borzycki, K.
Powiązania:: https://bibliotekanauki.pl/articles/308112.pdf
Data publikacji:: 2008
Wydawca:: Instytut Łączności - Państwowy Instytut Badawczy
Tematy:: highly doped fiber

Opis:: The paper presents optical measurements - spectral loss, OTDR and PMD, temperature cycling and mechanical tests - bending, twist and crush, performed on Yb-doped single mode fibers and small-core photonic crystal fibers (PCF). Several issues related specifically to characterization of such specialty fibers, like measurement errors and artifacts as well as coupling of test instruments to samples are presented. Of particular importance is reliable and low-loss fusion splicing of specialty fibers to standard single mode fibers (SMF), as most commercially available fiber test instruments are fitted with SMF interfaces only.
