CJYXFCH Drop Cable
CJYXFCH is the fully non-metallic version of the bow-shaped FTTH drop cable. The model code breaks down as: GJ - indoor-grade construction; YX - flat bow profile; F - FRP (fiber-reinforced plastic) strength member; C - self-supporting design; H - flame-retardant low-smoke zero-halogen sheath. Every load-bearing element is made of composite material instead of steel, which turns this otherwise ordinary drop into a specialist tool for environments where metal is a liability.
The optical core remains ITU-T G.657A bend-insensitive single-mode fiber, performing like G.652D while surviving the sharp corners and staple points of last-meter routing. One- and two-fiber builds support both GPON and EPON, and the cable coils by hand with no winches or special rigging.
What makes CJYXFCH different is where it can go. With no metallic path end to end, it can be attached to structures beside high-voltage lines, routed through thunderstorm-prone regions, and installed where metal-on-metal contact must be avoided. It also removes two operational headaches of metallic drops: earthing hardware and the appeal to scrap-metal thieves.
Applications
Lightning-prone rural and highland routes: With no metallic conductor, the cable offers no path for a strike or surge current toward the building.
Corridors beside high-voltage lines and electrified railways: With no steel messenger to energize, the drop shares attachment points with power infrastructure safely.
Petrochemical plants, fuel depots, and mines: In potentially explosive atmospheres, removing metal-on-metal hardware eliminates a spark source and simplifies compliance with site safety rules.
High-theft districts: FRP has virtually no scrap value, removing the incentive that drives thieves to cut steel-messenger drops for resale.
Coastal towns and salt-laden environments: Nothing in the cable rusts; FRP and the LSZH jacket shrug off humid salt air that eventually attacks galvanized steel.
Historic or listed buildings: Where drilling for earthing electrodes or fitting bonding clamps is prohibited, the grounding-free cable protects the fabric of the building.
Temporary network rollouts: Disaster-relief and event networks can be strung quickly and later removed without leaving any earthing hardware behind.
Advantages
Zero grounding work: No earthing kits, bonding clamps, or arrestors to buy, install, or inspect - saving parts, labor, and paperwork.
No induced-current engineering: The clearances and bonding calculations required for metallic messengers disappear from the project scope entirely.
Safe in hazardous zones: The all-dielectric design supports deployment wherever spark-free practice is mandatory.
Theft-resistant: Cutting the cable yields nothing saleable, so drop sections become far less tempting targets.
Corrosion-proof construction: FRP and LSZH remain stable in salt spray, humidity, and industrial fumes across the cable's service life.
Lighter handling: The composite build weighs less than its steel-reinforced sibling, easing aerial work and reducing loading on poles and building brackets.
Simpler fault-finding: With no metallic component to test, bond, or re-earth after storms or nearby works, troubleshooting the drop reduces to checking the fiber itself.

FAQ
Q1: What does the CJYXFCH code mean, and how is it different from GJYXCH?
CJYXFCH uses the same bow-shaped drop profile but replaces the steel messenger of GJYXCH with an FRP strength member, making the entire cable all-dielectric. GJYXCH remains the better choice where maximum attachment-point spacing is the priority.
Q2: Does an all-dielectric cable remove all lightning risk?
It removes the cable as a metallic lightning path, which is the main hazard in subscriber drops. Equipment at the ONT end should still follow standard surge protection practice, because power and other services can carry surges independently of the fiber.
Q3: Can this cable be installed inside explosive atmospheres?
The all-dielectric construction eliminates spark sources within the cable itself, supporting deployment in hazardous areas subject to site-specific approval. Installation hardware and any metallic fittings at the ends must still comply with the classification of the location.
Q4: What span distance can the FRP strength member handle?
FRP provides solid but lighter reinforcement than steel, so the recommended spacing between attachment points is shorter - typically up to 60 to 80 meters depending on wind zone, versus about 100 meters for steel-messenger versions. Span sizing is confirmed during quotation.
Q5: Is earthing still required anywhere?
None for the cable itself - that is the point of the design. The ONT still requires an approved power supply, and its earthing should follow the manufacturer's instructions.
CJYXFCH drops are supplied on small drums in one- or two-fiber versions, with lengths matched to route surveys and optional factory-fitted connectors. Sheath color, printing, and drum size can be customized, and span engineering support is available for demanding wind or terrain conditions. Samples and quotations on request.
