Decrease of the Link PMD by Fiber Exchange and Investigation of the PMD Distribution along Buried Optical Fibers with a POTDR
I. INTRODUCTION The fiber network of most network operators generally comprises a heterogeneous mixture of fibers and cables, produced by different vendors over many different years. Thus, there can be a correspondingly important variation in the physical properties of deployed fibers. Along with fiber attenuation and chromatic dispersion, polarization mode dispersion (PMD) is an important […]
Оптический рефлектометр
Опти́ческий рефлекто́метр (англ. OTDR, Optical Time Domain Reflectometer) — прибор для измерения параметров волоконно-оптических линий передачи (ВОЛП). Принцип работы прибора основан на анализе отражённых оптических импульсов, излучаемых рефлектометром в оптическое волокно. Измерения с помощью оптического рефлектометра основаны на явлении обратного рассеяния света в волокне и на отражении света от скачков показателя преломления. Импульсы света, распространяясь […]
Fujikura 62S, 61S Fusion Splicer
The Fujikura 62S provides active core alignment splice loss performance while utilizing a conventional wind protector and tube heater design. An alternative to the fully automated core-alignment model 70S, the 62S includes an auto start feature for both the splicing and tube heating process that minimizes the steps necessary to process splices. With a shrink […]
