Reduction Mircoduct Connector
This is a highly specialized component used in fiber optic cable installation. A Reduction Microduct Connector is a passive mechanical fitting designed to join two microducts of different diameters seamlessly. Its primary purpose is to enable a smooth transition for fiber optic cables or sub-ducts as they pass from a larger duct into a smaller one, or vice-versa, within a telecommunications infrastructure.

Microduct reduction connectors are essential for installing and maintaining microduct systems. Made from high-quality clear polycarbonate (Makrolon 2807) by Bayer, they connect different segments of microducts, especially when moving from direct buried (DB) to direct installation (DI) ducts in homes and offices. Starting at 3 mm in size, these durable connectors are easy to install and provide reliable performance in telecommunications, data centers, and commercial buildings. Talk to us
How and Where Is It Used?

✅ A typical installation scenario involves a fiber distribution hub or an access point (like a manhole or a pole mounted closure).
✅ A main distribution microduct (e.g., 25mm/40mm) arrives at the closure.
✅ Multiple smaller microducts (e.g., 10mm/12mm) are destined to run to individual customers.
✅ A Reduction Microduct Connector is installed at the interface point inside the closure.
✅ The large duct is connected to the large end of the reducer.
✅ The small microduct is connected to the small end of the reducer.

This creates a sealed, continuous pathway for the fiber cable to be blown or pulled from the main network into the specific pathway leading to a single home.

✅ Smooth Transition: It provides a tapered, smooth internal pathway that guides the fiber cable or a smaller microduct (a "sub-duct") from a large diameter to a small diameter without sharp edges or abrupt changes in direction.

✅ Sealing: It often incorporates sealing features (like O-rings or gel seals) to maintain the integrity of the duct system. This is critical for keeping out moisture, dirt, and debris, which can damage the fiber cables.

✅ Mechanical Connection: It creates a strong, secure, and often snap-fit or push-fit connection between the two different-sized microducts, ensuring the network remains physically robust.

✅ Blown Fiber Compatibility: These connectors are essential for networks that use air-blown fiber (ABF) technology. In ABF, cables are installed by being "blown" through the ducts using compressed air. A smooth, sealed transition is vital for maintaining the airflow needed to propel the cable over long distances.

What Problem Does It Solve?

In modern Fiber-to-the-Home (FTTH) or Fiber-to-the-Premises (FTTP) networks, a main larger duct (e.g., 40mm) is often run through a neighborhood. From this main duct, smaller microducts (e.g., 10mm, 12mm, 14mm) branch off to individual homes or buildings.

The challenge is: How do you protect the fiber cable as it transitions from the spacious main duct into a much narrower pathway without causing friction, damage, or a bottleneck? The Reduction Microduct Connector solves this problem.
