Even though they are still predominant in the industry, the use of halogenated compounds in wire and cable has decreased over the past several years. Polymers such as PVC are being phased out in certain applications, especially in enclosed, high-density cable applications. Relatively new low-smoke and zero (or low) halogen compounds, which are typically polyolefin […]

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 […]
