Fast and stable internet is vital for daily life. From video calls to online classes, people depend on steady connections. FTTH technology uses light energy instead of electricity, offering faster, more reliable speeds with less delay. Fiber optic cables deliver data directly to homes and offices. Jera Line, a well-known manufacturer of fiber optic wire cable, has a range of Drop flat cables developed for modern FTTH networks. These cables are designed for indoor and outdoor use as outdoor fiber optic cable, offering strength, flexibility, and longevity. Products like GJYXFCH and GJYXCH simplify fiber internet installations.
What Makes Drop Flat Cables Special
Drop flat cables are the final link between the main fiber network and the user’s home or building. This part of the connection is commonly referred to as the "last mile." The design of these cables is flat and small, which aids in easily fitting them along walls, poles and trays. They are lightweight but strong, and therefore easy and safe to install. A fiber optic wire cable used in FTTH systems needs to handle bending, pulling, and exposure to outdoor conditions. Drop flat cables from Jera Line are constructed with protective layers that protect from pressure, heat and ultraviolet (UV) light. Each cable is carefully tested to strict quality standards. These features make them suitable for long-term use without needing frequent maintenance and performance loss.
Structure and Design of Jera Line Drop Flat Cables
Jera Line’s drop flat cables come in different models, including the 4 core fiber optic cable and 2 core fiber optic cable types. The “core” in this context refers to the number of optical fibers inside the cable. Each fiber core carries light signals that transmit data over long distances with very little loss. For example, the 4 core fiber optic cable has four separate fibers protected by a flat sheath. It is often used when multiple connections or higher capacity are needed. The 2 core fiber optic cable is used when only two connections are required, such as linking one building or apartment. Inside the cable, there are steel or fiber-reinforced plastic (FRP) rods that act as strength members. These help the cable handle pulling force during installation. The outer sheath is LSZH (Low Smoke Zero Halogen), which doesn't emit harmful gases or thick smoke when burning, making it safer for indoor and outdoor use. The GJYXFCH type includes steel strength members, while the GJYXCH type uses FRP rods. Both types are made to meet the needs of different environments. The steel-reinforced cables provide extra strength for outdoor routes, while FRP-based cables are preferred for indoor applications because they are lightweight and non-metallic.
Designed for Outdoor and Indoor Applications
Jera Line’s drop flat cables are suitable for a wide range of installations. Jera Line’s cables can be used outdoors or indoors as outdoor fiber optic cable, attached to poles, walls, or buildings. Their protective layers shield against rain, dust, sunlight, and temperature changes. The flat shape makes placement in trays or conduits easy, and the smooth surface and small size assist handling and installation in tight spaces. Their strength and flexibility enable reliable performance when bent or twisted, ideal for telecom companies building FTTH networks. Their drop flat cables reduce the risk of damage during installation and continue to perform well for many years.
High Performance and Reliability
Each Jera Line cable goes through several tests before leaving the factory. The company uses Optical Time Domain Reflectometer (OTDR) testing to check the quality of the fiber core. OTDR testing helps find any possible faults or signal losses within the cable. It measures connection quality and length, testing at 1310, 1550, and 1625 nm to confirm low attenuation: under 0.4 dB/km at 1310 nm and 0.3 dB/km at 1550 nm, ensuring compatibility. Jera Line’s drop flat cables provide strong data transmission, withstand short-term pulling up to 200 N, and crushing loads up to 2200 N per 100 mm, enduring stress during installation or outdoor use without performance loss.
Durability in Harsh Environments
Durability is crucial for outdoor fiber optic cables. Jera Line's cables withstand harsh weather from -60°C to 70°C, resist UV cracking, and offer fire protection with LSZH. These features suit installation between buildings, industrial sites, or telecommunication supports. The GJYXFCH model, reinforced with steel, offers added strength for aerial installations where tension is higher. The GJYXCH version, with FRP rods, provides flexibility and is completely dielectric, meaning it contains no metal and is safe from lightning or electrical interference. Both designs are designed to achieve reliable and durable performance.
Role in Fiber-to-the-Home Networks
In modern FTTH systems, the role of drop flat cables is crucial. They form the last section of the network that brings fiber connectivity directly into homes, offices, and factories. The performance of this final connection affects the entire system’s efficiency. Jera Line’s drop flat cables make it easier for network installers to connect users quickly and safely. The compact design allows direct cable runs from the distribution point to the customer's premises, enabling faster, reliable connections for video, gaming, cloud, and remote work. Jera Line's cables make high-speed fiber more accessible and reliable.
Why Testing and Quality Control Matter
Fiber networks need consistent quality to perform well. Jera Line performs thorough testing during every step of production. The internal laboratory checks not only the optical performance but also the strength, flexibility, and fire safety of each cable. The company uses advanced testing devices such as EXFO FTB-1 to inspect all FTTH drop cables. Every cable batch undergoes OTDR reflection testing to confirm quality before shipping. This careful approach ensures customers receive cables that meet global standards for reliability and safety. Such quality control measures also make Jera Line products suitable for large-scale projects involving hundreds or thousands of connections. With reliable materials and precise testing, their drop flat cables remain a trusted choice in the telecommunications industry.
Environmental and Safety Considerations
Jera Line’s cables are made with attention to environmental safety. LSZH jackets burn cleaner with less toxic smoke and are safer. Their lightweight design reduces waste. The non-metallic options, such as the GJYXCH model, provide electrical safety by preventing current flow, which is especially important in densely built areas. The company’s ongoing testing and improvements ensure that all cables maintain both performance and environmental safety standards.
Conclusion
The rise of high-speed internet depends heavily on strong and dependable infrastructure. Jera Line’s drop flat cables have become an important part of modern FTTH networks by offering strength, flexibility, and high transmission quality. Whether using the GJYXFCH or GJYXCH type, each fiber optic wire cable is made to perform these cables excelling indoors and outdoors, combining durability, safety, and easy installation, making them ideal for expanding fiber networks. Jera Line offers 2 core fiber optic cable and 4 core fiber optic cable, including outdoor options. Their strict testing and design standards ensure fast, reliable, durable internet that keeps communities connected.
