Abstract. Further development of modern optical communication systems requires the
elimination of factors that limit the capabilities of the system and increase the efficiency and
quality of the system's transmission. Dispersion values in long-distance fiber-optic communication
lines are significantly high, which requires the use of special technical solutions to compensate
for dispersion distortions for an optical signal of any format. The article is devoted to the issues
of increasing the efficiency of using dispersion compensators.
Keywords: fiber-optic communication systems, communication line, optical fiber, signal,
optical channel, dispersion, dispersion compensation, optical amplifier, efficiency, transmission
quality.

Optik tolada nafaqat xromatik dispersiya (masalan, liniyaning 1000 km uzunligida G.652
tolalarda 550 nm to‘lqin uchun yig‘indi xromatik dispersiya taxminan 18 000 ps/nm ni tashkil
etadi), balki apparaturalarning optik qurilmalarida to‘planadigan PMDdan birmuncha kichik
dispersion buzilishlar qiymati (masalan,
G.652 PMD=0,2 пс/км
0,5
tolada 1000 km liniya
uzunligida dispersiya 66 ps ni tashkil etadi) ham optik signallarni uzatish imkoniyatlarini
cheklaydi va kompensatsiyalash bo‘yicha echimlarni talab qiladi. Bular maqolaning dolzarbligini
belgilaydi. Maqolada zamonaviy optik aloqa tizimlarida dispersiya kompensatorlarini qo’llash
samaradorligini takomillashtirish tahlillarini amalga oshirish maqsad etilgan.
