GJYXCH 1,2,4 Cores Self-supporting Fiber Optic FTTH Drop Cable

GJYXCH is a Self-supporting drop cable used for connecting between the main network and the end user. It is widely used in FTTH. This cable have simple structure. it is self-supported by diameter 1.0mm steel wire.Two steel wire are placed in parallel making the drop cable have more tension. The fiber in the center is G.657.A1 helping the drop cable has good bending performance. Outer Jacket LSZH wrap the FRP G657 fibers and messenger wire in a flat, bow-shaped shape.

■ GJYXCH FTTH Drop Cable Production Process

1. Color the bare G657A1 fibers using a coloring machine with distinct identification colors:
   • 1 core: Blue
   • 2 cores: Blue, Orange
   • 4 cores: Blue, Orange, Green, Brown
2. Straighten, clean, and dry the galvanized steel wires to ensure no bending or eccentricity during the subsequent molding process.
3. Feed the colored fibers, two 0.4mm steel wires, and one 1.0mm steel wire into the cabling machine, arranging them in a butterfly-shaped cross-section. Then extrude an LSZH outer sheath via a sheath extruder to form the butterfly drop cable.
4. Finally, wind the finished cable onto plastic drums (integrated plastic reels) in specified lengths of 1000m/drum or 2000m/drum. The finished cabled drums are then transferred to the quality inspection station for testing.

■ GJYXCH FTTH Drop Cable Quality Inspection Process

1. Attenuation test of bare G657A1 optical fiber
2. Colored coating adhesion test by repeated wiping with alcohol after fiber coloring
3. Density and aging resistance tests of LSZH sheath compounds
4. Attenuation test, tensile test, crush test, bending test, torsion test and temperature cycling test on finished drop cables
5. Final flame retardant and low smoke emission tests

Rural Village FTTH Aerial Deployment Project

This project covers a total of 120 households, with span distances ranging from 30 to 80 meters and a total cable length of approximately 18 km.GJYXCH-2B6a (G657A1 optical fiber, LSZH sheath, 1.0 mm messenger wire + 2×0.4 mm strength members) is adopted.The cable is installed directly on poles using hoops and cable hooks without additional steel strands.The bending radius of the fixed cable shall be no less than 15 mm.SC mechanical splices are used for subscriber termination, with insertion loss ≤ 0.3 dB.For single-subscriber acceptance, the attenuation measured by optical power meter is ≤ 0.4 dB/km (including splices).For whole-section acceptance, no reflection peaks and no breakpoints are allowed in OTDR testing.
