3 mm Microduct System for FTTH Networks in MDUs
When installing fiber to the home (FTTH) in Multi Dwelling Units, the challenge is to reach all apartments in the most convenient and cost effective way. This article presents results from practical and theoretical studies regarding 3mm ducts for Air-Blown Fiber installations in indoor environments. By reducing the diameter from typically 5mm to 3mm the cross section is reduced by 64%, allowing fo existing narrow risers to be used and costly core drilling avoided.
