GYTY53 Direct Buried Fiber Cable

GYTY53 direct buried fiber cable has high strength materials and can withstand harsh underground environments. It can be used for long-distance communication and local area network (LAN) applications.

It has a wide temperature range and can be directly buried in the ground to save the cost of duct and overhead installation. It also features a full section water blocking structure and rodent resistance.

Loose Tube Stranding Technology

GYTY53 armored fiber optic cable uses a central tube design with stranded loose tube fibers to provide superior strength and water resistance. The stranded loose tube design isolates the fibers from installation and environmental rigors, ensuring the cables remain fully functional. The loose tube design also improves optical performance by reducing strain on the fibers.

The single-mode and multi-mode optical fibers are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. A steel wire, sometimes sheathed with polyethylene (PE) for a cable with a high fiber count, is located in the center of cores as a metallic strength member. The tubes and fillers are stranded around the strength member to form a compact, circular cable core. An Aluminum Polyethylene Laminate (APL) is applied around the core to protect it from moisture ingress and to prevent water from leaking into the fibers.

The loose tube design provides a good secondary excess length, allowing the fibers to move freely in the tube during installation and maintaining gyty53-fiber-optic-cable-direct-buried their structural integrity. It also makes the cable suitable for direct burial, as it is more resistant to longitudinal stress and is less susceptible to damage from rodents or other field animals. In addition, the corrugated steel tape armoring and double PE sheath provides excellent crush resistance and rodent protection.

Water-Blocking Structure

During the production process of GYTY53 optical fiber cable, a special filling compound is used to help prevent the longitudinal migration of water. The gel is carefully applied to the cable’s shield and helps to fill in any gaps. This reduces the likelihood of moisture traveling through the cable’s internal conductors, thus increasing the lifespan and efficiency of the product.

The gel used to make up the water blocking structure is made of a combination of cellulose and superabsorbent polymer. It’s important that the product be made using high-quality materials so that it can hold up to harsh environments.

In addition to preventing water migration, the gel also improves the overall strength and crush resistance of the cable. This makes it ideal for use in ducts, conduits, and direct burial applications.

Another popular method of waterproofing is the use of dry water-blocking technology. This involves wrapping the inner cable components with an absorbent layer of impregnated fiber, either yarn or tape. Whenever water gets through the sheath to that layer, it will swell up and stop any further migration of water. This has been estimated to double or even triple the lifespan of cables that are regularly exposed to wet environments.

A typical dry waterproofing material is made of a mix of expanded fiber or expanded powder with polyacrylate. When it’s subjected to water, the polyacrylate will force its molecular chains to stretch out from their curled state, which causes it to expand rapidly. This is what causes the water-blocking function.

Corrugated Steel Tape Armoring

Unlike steel wire armoring, corrugated steel tape armoring is less likely to be affected by the mpo-patch-cords-patch-cable-assemblies electromagnetic field generated by other metals. Its small spaces between the individual steel strips make it less vulnerable to magnetic coupling and reduce interference with nearby circuits. This makes it ideal for use in fiber optic cables. Moreover, it has a better overall tensile strength and crush resistance than wire armoring.

OPTICO offers both single-mode and multi-mode GYTY53 directly buried optical cable for outdoor communication applications. Its central tube design and stranded loose tube fibers provide excellent tensile strength, crush resistance, and durability. In addition, the water blocking materials protect it from rain and other environmental factors.

This type of cable is designed for direct buried and duct applications where mechanical damage is a concern. The loose tube structure provides good secondary excess length and allows the fibers to move freely in the tube, which mitigates stress during longitudinal movements. Additionally, the metallic strength member provides exceptional rodent protection.

The cable is composed of two to 24 250um direct burial fibers in a single gel filled loose tube, surrounded by a nonmetallic E-glass strength member and a Low Smoke Zero Halogen (LSZH) sheath. It also features a double sheath design that improves crush resistance and moisture-proof performance. The sheath is then covered with corrugated steel tape armoring and a PE outer sheath.

Double Polyethylene Sheath

Direct burial fiber cable is used in telecommunications networks for long distance communication. It is normally buried underground to minimize external damage. This type of cable is available in various specifications and is made to order based on your specific requirements. It is a great option for areas that need a durable, rugged armored fiber cable. Having been on the market for three years, GYTY53 has gained popularity in the industry and is highly recommended by many technicians.

The GYTA53 outdoor cable has a central strength member and gel-filled PBT loose tubes. It is suitable for duct and direct burial applications, and the core count can range from 2 to 216 fibers. The loose tube jelly-filled structure of the cable provides critical protection to the fibers and is resistant to water. This makes it an ideal choice for telecommunications networks that need high performance in harsh environments.

The cable has a double polyethylene sheath that protects it from the elements and prevents field animals from damaging the internal fibers. It also offers good mechanical properties and abrasion resistance. In addition, it has an aluminum polyethylene laminate (APL) inner sheath, which effectively lowers the external mechanical loading. The sheath is longitudinally covered with corrugated steel tape armoring, and the final layer is a durable PE outer sheath. This combination of protective layers ensures the longevity of the cable and provides excellent crush and abrasion resistance.
