Product Description
The structure of the GDTA/S Stranded Photoelectric Composite Cable involves inserting single-mode or multimode optical fibers into
a loose tube made of high-modulus polyester material, filled with a waterproof compound. At the center of the cable core is a metallic central strength member;
for certain core counts, a layer of polyethylene (PE) is extruded over the central metallic strength member.
The loose tubes and insulated copper wires of required specifications are stranded around the central strength member to form
a compact circular cable core, with the gaps inside the core filled with water-blocking material. The cable is completed with a
longitudinal application of Corrugated Aluminum Tape (APL) or Corrugated Steel Tape (PSP), followed by the extrusion of a Polyethylene (PE) outer sheath.
Product Features
Optoelectronic Integration: Solves equipment power supply and signal transmission issues in a single cable, providing centralized monitoring and maintenance for equipment power.
Enhanced Power Manageability: Improves power supply management and reduces power coordination and maintenance costs.
Reduced Procurement & Installation Costs: Lowers purchasing expenses, avoids secondary wiring, and saves overall construction costs.
Precise Excess Fiber Length Control: Accurately controlled fiber excess length guarantees superior tensile strength and excellent temperature stability.
BBU to RRU Connectivity: Primarily used in distributed base station DC remote power supply systems to connect Baseband Units (BBU) and Remote Radio Units (RRU).
Versatile Deployment: Suitable for duct pulling or aerial self-supporting installations.

Values are typical reference data taken from the official Huifiber datasheet. Confirm the final specification against the datasheet before ordering.
Huifiber GDTA/S stranded photoelectric composite cable combines G. 652. D optical fibers and insulated copper wires in a single robust design.
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.
