OM3 Armored 12-144 Cores Figure 8 Fiber Optic Cable Self-Supporting Aerial GYTC8A Cable

The OM3 Armored Figure 8 Outdoor Aerial Optical Fiber Cable GYTC8A is a self-supporting aerial multimode cable that combines OM3 high-bandwidth 50/125μm multimode fiber with the GYTC8A integrated figure-8 armored structure. It is designed for outdoor high-speed short-to-medium distance interconnection scenarios that require both mechanical protection and 10G+ transmission capabilities.

The cable complies with industry standards YD/T 1155-2 and IEC 60794-1, and is widely used in last-mile access, metropolitan area network aerial lines, and similar deployments.

Its integrated figure-8 cross-section unites the optical transmission unit and the high-tensile galvanized steel messenger within one continuous PE outer sheath, making it a cost-efficient, high-reliability workhorse for global telecom aerial network construction.

• G — Outdoor communication optical cable
• Y — Stranded PBT loose tubes, gel-filled
• T — Self-supporting
• 8 — Figure-8 cross-section
• A — APL (aluminum-polyethylene laminate) moisture barrier

1. 250 μm fibers in PBT loose tubes with water-blocking jelly.
2. Loose tubes and fillers stranded around a central steel strength member.
3. Cable core wrapped with APL tape (moisture/oxygen barrier).
4. Fiber lobe and stranded steel messenger wire molded into one PE figure-8 sheath.
5. No separate messenger strand required.

• Self-supporting figure-8 structure: No additional steel strand messenger wire is required during aerial laying, which directly reduces construction difficulty and installation cost, and enables quick deployment along existing utility pole lines.
• OM3 high-bandwidth performance: The laser-optimized core design far exceeds the bandwidth limit of OM2, stably supporting 10G Ethernet transmission over 300 meters and remaining compatible with low-cost 850nm VCSEL optical modules.
• Armored enhanced protection: The APL aluminum armored layer provides excellent lateral pressure resistance, rodent bite resistance and moisture sealing performance, adapting to harsh outdoor environments such as humid coastal areas and suburban wild areas.
• Excellent environmental stability: The hydrolysis-resistant loose tube and special water-blocking ointment ensure that transmission performance remains stable over the long term under extreme temperature changes and long-term aerial wind sway.

• Data center park interconnection: Aerial high-speed links between different buildings in the park, supporting 10G short-distance interconnection without buried pipeline construction.
• Industrial park & campus high-speed network: Aerial deployment of 10G backbone links in manufacturing parks, university campuses and logistics parks, with fast deployment and low cost.
• Outdoor high-definition monitoring networking: Aerial connection of 4K/8K high-definition surveillance cameras distributed along roads, scenic spots and borders, supporting stable high-bandwidth video backhaul.
• Temporary large-scale event network: Quickly erect 10G high-speed optical lines for large exhibitions, sports events and outdoor performances, with no need for complex fixed facilities.
• Old community FTTO high-speed transformation: Aerial laying of the last 100-meter 10G optical fiber link in old residential areas, making full use of existing overhead pole resources.
