Loose Tube Armored Flame-retardant Direct Buried Cable
Product Features
Excellent mechanical and temperature performance.
Resistant to high and low temperature cycles, resulting in anti-aging and a longer lifespan.
Loose tube stranding cable core ensures stable cable structure.
Single steel wire serves as the central strength member to withstand axial loads.
100% core filling with water prevents cable jelly to ensure cable watertightness.
Aluminum tape longitudinally covers cable core as a moisture barrier.
Inner sheath effectively reduces external mechanical loading.
Corrugated steel tape longitudinally covers cable core and provides good crush resistance.
Outer sheath protects cable from ultraviolet radiation.

Packing And Mark
OYI cables are coiled on bakelite, wooden, or ironwood drums. During transportation, the right tools should be used to avoid damaging the package and to handle them with ease. Cables should be protected from moisture, kept away from high temperatures and fire sparks, protected from over-bending and crushing, and protected from mechanical stress and damage. It is not allowed to have two lengths of cable in one drum, and both ends should be sealed. The two ends should be packed inside the drum, and a reserve length of cable not less than 3 meters should be provided.
The color of cable markings is white. The printing shall be carried out at intervals of 1 meter on the outer sheath of the cable. The legend for the outer sheath marking can be changed according to the user's requests.
Test report and certification provided.

Self-supporting Figure 8 Fiber Optic Cable
The 250um fibers are positioned in a loose tube made of high modulus plastic. The tubes are filled with a water-resistant filling compound. A steel wire is located in the center of the core as a metallic strength member. The tubes (and fibers) are stranded around the strength member into a compact and circular cable core. After an Aluminum (or steel tape) Polyethylene Laminate (APL) moisture barrier is applied around the cable core, this part of the cable, accompanied by the stranded wires as the supporting part, is completed with a polyethylene (PE) sheath to form a figure 8 structure. Figure 8 cables, GYTC8A and GYTC8S, are also available upon request. This type of cable is specifically designed for self-supporting aerial installation.

OYI-ATB02C Desktop Box
OYI-ATB02C one ports terminal box is developed and produced by the company itself. The product’s performance meets the requirements of industry standards YD/T2150-2010. It is suitable for installing multiple types of modules and can be applied to the work area wiring subsystem to achieve dual-core fiber access and port output. It provides fiber fixing, stripping, splicing, and protection devices, and allows for a small amount of redundant fiber inventory, making it suitable for FTTD (fiber to the desktop) system applications. The box is made of high-quality ABS plastic through injection molding, making it anti-collision, flame retardant, and highly impact-resistant. It has good sealing and anti-aging properties, protecting the cable exit and serving as a screen. It can be installed on the wall.

Simplex Patch Cord
OYI fiber optic simplex patch cord, also known as a fiber optic jumper, is composed of a fiber optic cable terminated with different connectors at each end. Fiber optic patch cables are used in two major application areas: connecting computer workstations to outlets and patch panels or optical cross-connect distribution centers. OYI provides various types of fiber optic patch cables, including single-mode, multi-mode, multi-core, armored patch cables, as well as fiber optic pigtails and other special patch cables. For most of the patch cables, connectors such as SC, ST, FC, LC, MU, MTRJ, and E2000 (with APC/UPC polish) are available. Additionally, we also offer MTP/MPO patch cords.

Central Loose Tube Stranded Figure 8 Self-suppo...
The fibers are positioned in a loose tube made of PBT. The tube is filled with a water-resistant filling compound. The tubes (and the fillers) are stranded around the strength member into a compact and circular core. Then, the core is wrapped with swelling tape longitudinally. After part of the cable, accompanied by the stranded wires as the supporting part, is completed, it is covered with a PE sheath to form a figure-8 structure.
