GJYXFCH FTTH Drop Cable: Complete Guide to Specifications, Materials & Installation
As the backbone of fiber-to-the-home (FTTH) networks, GJYXFCH drop cables play a pivotal role in delivering high-speed broadband to end-users. This self-supporting "figure 8" cable combines compact design with robust performance, making it ideal for last-mile connectivity. Below is a comprehensive guide to its key specifications, materials, installation best practices, and why Chinese manufacturer JERA LINE stands out as a top supplier.
GJYXFCH cables are defined by their precise technical parameters that ensure reliable signal transmission. Typically featuring a 2.0×5.0mm cross-section (±0.2mm tolerance), they support 1-12 fiber cores with single-mode options including G.652.D and bend-insensitive G.657.A1/A2 fibers . The optical performance is exceptional: attenuation ≤0.4dB/km at 1310nm and ≤0.3dB/km at 1550nm, with a cable cut-off wavelength ≤1260nm . Mechanically, they withstand short-term tensile strength of 600N and long-term 300N, with crush resistance up to 2200N/100mm—critical for outdoor deployment . Operating temperature ranges from -60℃ to +70℃, enabling performance in extreme climates . All specifications comply with international standards including IEC 60794, ISO, and CE.
The durability of GJYXFCH cables stems from premium materials. The outer sheath uses low-smoke zero-halogen (LSZH) plastic, which is flame-retardant, UV-resistant, and environmentally friendly . Two parallel phosphated steel wires act as strength members, providing structural integrity without adding excessive weight (cable weight is approximately 20kg/km) . For indoor variants, FRP (fiber-reinforced plastic) rods replace steel for non-conductive safety . These materials undergo strict quality control—JERA LINE, for example, uses ISO 9001:2015-compliant raw materials processed in its dedicated plastic molding workshop.

Installation Best Practices
Efficient installation is key to maximizing GJYXFCH performance. The cable’s self-supporting design allows aerial deployment via poles or walls, with a minimum bending radius of 20mm (static) and 40mm (dynamic) . For midspan termination, use compatible splice closures with IP67 sealing to protect connections from moisture. Pre-terminated patch cords (SC/APC or SC/UPC) from JERA LINE simplify installation, reducing on-site labor time. Ensure proper slack storage and use manufacturer-approved clamps—JERA LINE’s complementary steel clamps and brackets enhance stability . Avoid over-tensioning during installation and use laser-marked components for easy identification.
