GJYBXCH and GJYFBXCH are self-supporting parallel FTTH drop cables in which the optical fiber unit and the messenger wire run side by side in a single figure-eight-free flat profile. The integrated messenger carries the mechanical load, so the cable can be strung between poles without a separate support strand — cutting installation time on aerial FTTH routes.
Both types place a tight-buffered or loose-tube fiber unit next to a steel or FRP messenger wire, bonded by a common LSZH or PE jacket with a web between the two elements. GJYBXCH uses a steel messenger for longer spans; GJYFBXCH uses an FRP (non-metallic) messenger where lightning immunity or electromagnetic isolation is required.
Match the messenger type to the environment: steel for the lowest cost on standard spans, FRP where the route runs near power distribution or through areas with frequent lightning. Confirm the span table for the fiber count you need — the same profile carries less load as the fiber unit grows. For subscriber drops terminating indoors, specify the LSZH jacket so the cable meets indoor fire requirements without a transition box.
What is the difference between GJYBXCH and GJYFBXCH? The final character indicates the messenger material — GJYBXCH uses a steel wire messenger, GJYFBXCH uses a non-metallic FRP messenger.
Do I still need a separate support wire? No. The self-supporting design means the messenger is bonded into the same jacket, so the cable can be clamped directly to the pole hardware.
Can the messenger be stripped for indoor routing? Yes. The web between the fiber unit and messenger can be split so the messenger is cut away at the entry point and only the fiber unit continues indoors.

Values are typical reference data taken from the official Huifiber datasheet. Confirm the final specification against the datasheet before ordering.
GJYBXCH and GJYFBXCH self-supporting parallel FTTH drop cable with integrated messenger wire. Steel or FRP messenger, 1 to 4 cores, no separate support strand.
Yes. Huifiber supplies cable under the buyer's own brand as well as under the Huifiber brand. Fibre count, jacket material, jacket print, drum marking, drum length, packaging and datasheet layout can all be produced to the customer's requirement, and the engineering team can work from a customer specification or adapt an existing construction to a new route requirement.
Every production batch is tested before it leaves the plant in Dongguan. Attenuation and geometry are measured on OTDR and optical bench equipment, and mechanical performance is verified against the datasheet for the construction. A factory test report is issued with each shipment, so an incoming inspection can be checked against the same numbers.
Send the fibre count and fibre type, the jacket material or fire rating, the route length or span and the drum length you need, the destination port or country, and any certification or test-report requirement. With those details the sales engineer can confirm the construction and return a quotation with an indicative lead time.
