The 7/5.5mm microduct is a versatile and widely deployed solution for air blown fiber installations across FTTH, outside plant (OSP), and data center environments. With a 7mm outer diameter and 5.5mm inner diameter, this duct size provides additional capacity compared to smaller microducts while maintaining installation flexibility and space efficiency.

Engineered from high-quality HDPE, the 7/5.5mm microduct supports efficient blowing distances and protects micro fiber cables from environmental stress, mechanical damage, and moisture intrusion.

Balanced Capacity & Flexibility

The 7/5.5mm size strikes a balance between compact design and cable capacity. It accommodates larger micro cables or higher fiber counts while still fitting easily within multi-duct bundles or existing conduits.

This makes it ideal for:

– Neighborhood FTTH distribution networks
– Campus fiber backbones
– Smart city infrastructure
– Industrial facilities
– Enterprise building risers

Network designers favor this size when moderate fiber counts are required without committing to larger duct systems.

Superior Air Blown Installation Performance

The internal geometry of 7/5.5mm microduct is optimized for air flow efficiency. Optional ribbed or lubricated inner linings reduce friction and extend blowing distances, allowing installers to cover longer spans with fewer access points.

Key advantages include:

– Faster deployment timelines
– Reduced installation labor
– Lower risk of fiber stress
– Easy cable upgrades
– Simplified network expansion

This modular deployment strategy ensures fiber infrastructure remains adaptable to evolving bandwidth requirements.

FTTH & Access Network Applications

In FTTH rollouts, 7/5.5mm microduct is frequently used as a feeder or distribution duct feeding multiple drop pathways. It provides sufficient internal space for higher fiber count micro cables serving clusters of homes or businesses.

Its flexibility allows installation through micro-trenching, directional drilling, direct burial, or placement within larger conduits.

Data Center Infrastructure

Within hyperscale and colocation data centers, 7/5.5mm microduct supports scalable fiber architecture. It enables operators to pre-install duct pathways throughout white space and mechanical areas, blowing fiber only as capacity is required.

Benefits for data centers include:

– Controlled fiber growth
– Reduced pathway congestion
– Improved airflow management
– Simplified high-speed upgrades
– Efficient cable lifecycle management

This approach aligns with the rapid evolution of 100G, 400G, and higher-speed optical networks.

Durability & Environmental Protection

7/5.5mm microduct offers strong resistance to abrasion, crushing, and environmental degradation. HDPE construction ensures long-term reliability in harsh outdoor environments and demanding industrial settings.

Available options may include:

– UV-stabilized materials
– Direct burial ratings
– Indoor LSZH variants
– Multi-way bundled assemblies
– Color-coded jackets for network identification

Future-Ready Fiber Deployment

Deploying 7/5.5mm microduct provides infrastructure that can evolve with bandwidth growth. Instead of oversizing cables or overbuilding capacity, operators gain the flexibility to expand incrementally.

This scalable model reduces capital expenditure, minimizes waste, and ensures long-term adaptability in competitive broadband markets.

For network builders seeking performance, flexibility, and future-proof fiber routing, 7/5.5mm microduct delivers the optimal combination of capacity and efficiency.
