1KM Blowing Distance 2 Core EPFU Fiber Singlemode And Multimode Optical Cable
Description
Enhanced Performance Fibre Unit (EPFU) is designed for blowing in 5/3.5mm microduct. Super small fibre bundle is manufactured with a special designed HDPE jacket to enhance air blowing performance. It is specifically engineered for blown fibre applications. The optical fibres are protected by inner acrylate and outer harder HDPE from external damage.
