Air-Blown Micro Fiber Optic Cable Technology
Air blown fiber is a revolutionary technology that can offer significant benefits in the construction of optical fiber cabling systems. It can reduce costs by allowing you to install ducts before you know how much fiber you need, and it also makes future network expansion easier and quicker.
GCYFTY loose tube air blown fiber optic cable is suitable for backbone network, metropolitan area network and access network. It features a non-toxic and harmless waterproof compound filled in HDPE, and it is reinforced with aramid yarns.
Loose Tube Structure
The loose tube structure of the air blown fiber optic cable GCYFTY is designed to make it easy for technicians to add new fibers in parallel and vertically without disturbing other optical fibers. This unique design is one of the main advantages of this technology. The new fibers can be blown into the tubes without any blockage or damage to existing fibers, allowing network expansion to be completed in less time and at lower cost than traditional cables.
The optical fiber in the loose tube is protected by a layer of jelly compound that prevents water from entering the core. The plastic tube sub-unit of the optical fiber is also robust, providing resistance to various mechanical loading. It can withstand the stress of winding and other factors, and it also protects the optical fiber from external impacts.
The air blown microfiber cable has an overall compact and lightweight design, making it easier to install in difficult-to-reach locations. It can be blown up to 1.6km at a time, which is significantly faster than traditional cables. It can be used in both premises and outside plant applications, allowing networks to grow on demand as capacity needs increase. The OFS MiDia portfolio of air blown cable designs provides exceptional performance and reliability value for both upgrades from existing fiber, and greenfield “grow as you go” deployments.
Enhanced Performance Fiber Unit
Air-blown micro fiber cable technology enables incremental optical network installations, easily adapted to the growth of end user demand. It also reduces the number of fiber splice points in the network, minimizing network maintenance and upgrade costs.
Using compressed air, installers blow a bundle of fibers into pre-installed micro ducts. The resulting point-to-point, splice-free installation provides air-blown-micro-fiber-optical-cable the flexibility needed for future upgrades without the need to re-build the entire system. This non-destructive upgrade method saves a significant amount of manpower and materials resources, not to mention time and money.
The micro tube bundles contain color-coded cells that provide routes through which installers can blow the optical cables for a splice-free, point-to-point installation. This approach minimizes the number of splice points in the network, which reduces overall maintenance and upgrade costs and improves system reliability.
The MiDia portfolio of loose-tube microcables are specifically designed for exceptional air-blown installation performance. From Telcordia GR-20 compliant designs to ultra-high density constructions, they allow providers to meet the needs of their most demanding networks. These products are an ideal solution for overriding existing cable in existing ducts, installation into unused innerducts and greenfield “grow-as-you-go” deployments. They are also compatible with ribbon microcables for even more flexibility in your network. Whether you’re deploying FTTHx or FTTB, we’ve got the right loose-tube design to suit your needs.
Loose Tube Extruded PE Sheath
This loose tube type fiber optic cable has a large amount of optical fibers stranded in the loose tube made of high modulus material and filled with a tube filling compound. These tubes are then twisted together along with a central metal-reinforced core, and surrounded by dry water-blocking fillers to form the cable core. A sheath of polyethylene is extruded outside the core. This sheath has a very thin profile to minimize the cable’s overall size and weight for easier handling and installation.
This design is common in air blown installations that require the cables to be pushed into ducts with air pressure. This type of installation method allows networks to expand on demand and saves money by avoiding the costs of trenching and civil engineering work. The stranded loose tube design also provides high fiber density, which maximizes the amount of fiber that can fit into small cable diameters.
Within the loose tube, aramid yarns or fiberglass-reinforced plastic rods are often fiber optic cable assembly industry used as strength members to increase the cable’s tensile strength and durability. In addition, a secondary coating is applied to the primary sheath to protect it against environmental factors and mechanical stress. The dual layer protection system is highly resistant to abrasion and tearing. This system also ensures that the cable maintains its performance over a wide temperature range and throughout its life.
Loose Tube LSZH Sheath
Loose tube fiber optic cable can be installed in microducts, which reduces deployment costs and provides a flexible network that can grow on demand. These cables are also suitable for aerial lashed or direct buried installations. The cable’s abrasion-resistant sheath is also designed to withstand harsh environmental conditions.
The loose tube design allows the coated optical fibers to “float” within a rugged, abrasion resistant oversized tube that is filled with gel. This helps to protect the optical fibers from environmental factors such as moisture, UV radiation, temperature fluctuations, and physical stress. It also helps prevent fiber damage by minimizing the amount of mechanical stress that is transferred from the sheath to the optical fibres.
In addition, the gel fills the gaps between the optical fibers and sheath to help provide a waterproof seal. This prevents water from entering the tube and damaging the fibers. The gel is also non-toxic and harmless, so it can be easily removed or replaced if necessary.
This cable includes 2 to 24 250um OM1, OM2, OM3, or OM4 multimode and single mode optical fibres in a 2.95 mm LSZH inner jacket with aramid strength members. It is available in various lengths and a variety of bending radius to meet different requirements. The cable’s special complex material loose tube ensures accurate fiber length balance and stable mechanical and temperature performance.
