Product Introduction - Uni-Tube Air-Blown Micro Cable
Spring has developed a compact Uni-Tube Air-Blown Micro Cable made specifically for efficient deployment within a Micro-Duct system that allows for blowing air through it. The Uni-Tube Air-Blown Micro Cable was engineered with the purpose of providing excellent performance when used for deploying Next Generation FTTx-type network access solutions at high density, as well as offering superior mechanical strength and lower costs associated with deployment. The technical specifications of this cable may be found on this product page, where network planners, ISPs, and integration engineers will be able to find details regarding its construction, performance, and installation characteristics that meet the EEAT compliance requirements.
What Is a Uni-tube Air-Blown Micro Cable?
The Uni-Tube Air-Blown Micro Cable, model GCYFXTY, allows for efficient airblown installations of compact optical cables containing optical fibers in a single loose tube with gel filler. This tube contains a robust aramid yarn core to provide additional strength above and beyond the design loads and is also encapsulated in a specially grooved envelope that provides additional stability while being deployed through micro-ducts. The Uni-Tube Air-Blown Micro Cable is generally utilized in:
FTTx/FTTH Access Networks
Power Utility Networks
Outdoor Environments Subject to Lightning and Other Harsh Weather Conditions
Air-Blown Distribution Systems for Micro-Ducts
Key Technical Advantages of Uni-tube Air-Blown Micro Cable
Compact Size & Lightweight Build
The extremely small diameter of the Uni-Tube Air-Blown Micro Cable reduces the amount of friction within micro-duct systems, which results in longer blowing distances and quicker installation times when deployed using the airblown method.
Tube-Filled Loose Tube Structure
The use of the micro cable with the loose tube structure will provide you with confidence in:
·Fiber protection.
·Moisture resistance.
·Stable optical performance when subjected to mechanical stress.
Grooved Outer Sheath for Improved Blowing Efficiency
The grooved outer sheath used on micro cables (Spring™ and GTYF™) has micro-grooves and tape applied to provide:
·A reduced cable-duct contact area
·Reduced friction during air blowing
·A greater blowing distance (up to 1,000 metres per cycle).
Replaceable & Upgradable Design
Because the architecture of the blow cable allows for the removal of old cables and the air blowing of upgraded fibre without the need for excavation, the cost of upgrading a network is significantly lower than with conventional networks.
Flexible Branching and Micro-Duct Accessibility
Micro-ducts can be cut at any point to branch the micro cable, thereby minimising:
·Handholes
·Splice closures
·Deployment costs
Comparison of Performance between Air Blown Micro Cable Families
