Description
Product Overview
GCYFY is a lightweight, all-dielectric air-blown micro fiber optic cable optimized for microduct networks. The outer sheath uses a low-friction HDPE with surface grooves to enhance jetting performance, while gel-free construction speeds splicing and handling. Available as central-tube builds for 2–12 fibers and micro-distribution variants for higher counts. This technology is the preferred choice for future-proof FTTx networks in Europe, Southeast Asia, and advanced North American metropolitan areas.
Where it’s used
- FTTx last-mile and access distribution in duct plants
- Campus/backbone microduct systems where space is limited
- Upgradeable routes that require staged fiber additions
- Utility and SCADA microduct corridors
Why air-blown
- Reuses the same microducts for future capacity; cables can be blown out/in.
- Lower and more uniform installation stresses vs. pulling.
- High fiber density in very small ducts, reducing civil works and storage.

Key Benefits
- Maximum fiber per duct: very small OD and gel-free design improve packing density and handling.
- Low-friction jacket with grooves: increases jetting distance and consistency.
- All-dielectric, aramid-reinforced: safe near power; no bonding/grounding.
- Fast deployment and upgrades: blow today, add capacity later using the same microducts
Ideal Deployment Scenarios
The GCYFY cable is specifically engineered for regions with established microduct infrastructure, widely adopted in:
- European FTTH Rollouts: Meeting stringent EU standards for high-density urban access networks.
- Southeast Asia Smart Cities: Ideal for rapid broadband upgrades in densely populated areas like Singapore and Kuala Lumpur.
- North American MDU & Campus Networks: Efficient for last-mile connections where conduit space is limited.
Options & Ordering
- Fiber counts: 2,4,6,8,12 central-tube; higher counts (24–144) available as micro-distribution/stranded variants on request.
- Jacket color/marking: black standard; meter marks per reel.
- Reel lengths: 1–6 km typical; custom cuts available.

FAQ
Q1. What duct size is recommended?
5.0/3.5 mm microducts are validated for 2–12F central-tube builds; consult us for larger counts and bundle ducts.
Q2. How far can I blow a 2–8F cable in one shot?
With 7–10 bar and clean 5/3.5 mm ducts, 500–1000 m is typical; 12F achieves ~500–800 m under similar conditions.
Q3. Is the cable gel-free?
Yes—resin-coated fibers and dry construction simplify splicing and cleaning.
Q4. What are the basic mechanical limits?
120 N short-term tensile, 1000 N/100 mm crush, and bend radius 20D/10D (install/static) for typical 2–12F builds.
