Air Blown Micro Cable

EPFU micro air blow Cable Low Friction Green ribbed GCYFXTY

Name: EPFU micro air blow Cable Low Friction Green ribbed GCYFXTY
Availability: InStock

The EPFU (Enhanced Performance Fiber Unit) is the core fiber-carrying element designed for air-blown installation into microduct systems. Unlike standalone microcables, EPFU units are deployed inside larger microducts alongside other EPFUs, enabling a 'pay-as-you-grow' fiber deployment strategy. Its distinctive green ribbed low-friction sheath enables blowing distances exceeding 2000m in a single operation, making it the foundation technology for future-proof, scalable fiber networks in 5G, FTTH, and smart city applications.

The EPFU Micro Air Blown Fiber Optic Cable Fiber Unit is a specific type of fiber optic cable designed for microfiber air-blown installation systems. This cable is used as the fiber unit within the air-blown installation process, which involves blowing or pushing microfiber cables through pre-installed ducts or pathways using compressed air. Enhanced Performance Fibre Units (EPFU) Optical fibers and filler elements are arranged in curing photosensitive resins to form a cable core. A low friction sheath is extruded outside the core. The EPFU fiber units contains microfiber optical fibers, which are thinner and more lightweight than standard optical fibers. Microfiber cables are specifically designed for air-blown installation systems due to their reduced air resistance and ease of deployment.

Frequently Asked Questions

1. What is the difference between EPFU and GCYFXTY microcable?

EPFU is a fiber unit designed to be deployed inside a microduct that may already contain other EPFUs — multiple EPFUs can share a single duct. GCYFXTY is a standalone microcable deployed into a dedicated microduct. EPFU is for incremental capacity growth; GCYFXTY is for initial deployment.

2. How many EPFU units can fit in one microduct?

Depending on the microduct ID and EPFU diameter, typically 1–7 EPFU units can share a duct. The fill ratio should not exceed 60% to maintain acceptable blowing distance. Our engineering team can calculate the optimal configuration for your duct network.
