GYTY53 Fiber Optic Cable

GYTY53 outdoor armored double jacket gel filled loose tube direct burial fiber cable is designed to be directly buried underground. It is mainly composed of 250um fibers held in gel-filled PBT loose tubes, wrapped around a phosphatized steel wire central strength member.

This type of cable is mainly used in harsh environments where it may be subjected to mechanical impact, such as direct burying or duct applications. It features corrugated steel tape and double PE sheaths to improve rodent resistance and crush performance.

1. Loose Tube Jelly Filled

GYTY53 outdoor stranded loose tube fiber cable is designed for the harsh environment of pipeline laying, direct burial deployment and overhead use. It features a central tube with multiple loose tubes containing 250mm optical fibers. The steel tape armor layer and double PE sheath improve the cable’s performance of pressure resistance, anti-static, bulletproof and moisture blocking. It also effectively prevents field animals from tearing and damaging the internal fiber.

Loose tube gel filled feature provides critical protection for the fiber by keeping water away from the core. The gel is a non-hygroscopic material that doesn’t transfer stress from the tube to the fibers themselves. This reduces the risk of intentional sabotage by humans.

The loose tube is typically made of a tough, abrasion resistant, oversized tube that’s filled with a special waterproof compound. This makes it a great choice for applications where moisture is a threat, such as in environments that gyty53-fiber-optic-cable-direct-buried experience high humidity or large temperature changes. However, gel-filled loose tube cables do require extra time to install because you have to clean the gel off the fibers before installation.

2. Corrugated Steel Tape Armor

Unlike braided fiber cables that utilize stainless steel tape, the corrugated steel tape armor feature provides an extra layer of mechanical strength for a more reliable cable. This is particularly helpful for outdoor applications where the cable could be susceptible to rodent bites, and also to reduce the possibility of any unnecessary downtime from the impact of heavy traffic or weather conditions.

This cable consists of 2 to 24 core OM1 or OM2 multimode optical fibers in single gel filled loose tube with water blocking LSZH sheath and corrugated steel tape armoring, metal central strength member and a PE sheath. It is suitable for use in direct burial or ducting.

The special tube filling compound ensures critical protection of fiber and resist the water. A metallic sheath locates in the center of core as a metallic strength member, and tubes (and fillers) are stranded around it. The sheath is then covered with a longitudinally applied APL moisture-resistant layer and a PSP protective coating, followed by a corrugated steel tape armor.

The sheath is mpo-patch-cords-patch-cable-assemblies then finished with a low-smoke halogen (LSZH) outer jacket to meet the needs of different environments.

3. Double PE Sheath

Unlike indoor fiber cables that are installed in a duct, direct burial cables are designed to be buried directly into the ground. This is done to reduce the risk of damage from external factors such as soil movement or corrosion. The extra sheaths and other protections on these cables help them resist these environmental factors and last longer.

This cable is specially designed for outdoor applications like long-distance communication and local area networks (LANs). It is available from 2 cores to 144 cores in both single-mode and multi-mode versions. The stranded loose tube design and water blocking materials make it suitable for use in wet environments. It also features steel wire/FRP as a central strength member and double sheaths.

The metal sheath provides excellent mechanical and temperature performance, whereas the double PE sheath improves its side pressure resistance, bulletproof, and moisture resistance performance. Moreover, it is also resistant to rodent bites. The precise excess fiber length control ensures critical fiber protection, enabling excellent hydrolysis resistance and high tensile strength. The cable is rated to withstand direct burial in the ground and meets standards YD/T 901-2001 and IEC 60794-1.

4. Water-Blocking

GYTY53 outdoor stranded loose tube fiber cable has the ability to resist water and is designed for direct burial. This feature ensures that the cable will survive harsh environments, such as changes in soil moisture and temperature. It also helps prevent the growth of harmful bacteria, which can disrupt service. The stranded loose tube design and water blocking materials help this cable perform well in outdoor applications, including long distance communication and local area network communication.

The 250um optical fibers are positioned in loose tubes made of a high modulus plastic material, which are filled with a water-resistant filling compound. A phosphatized steel wire central strength member locates in the middle of the core. The loose tube (and filler rope) twists around the strength member to form a compact and round cable core. The gaps between the loose tube and the central strength member are filled with a jelly-like waterproof filler, and PSP is longitudinally applied.

Corrugated steel tape armored and double PE sheath make this cable ideal for installation in harsh environments, such as direct buried application. It is also suitable for installation in ducts where rodent resistance and moisture resistance are required.

5. Steel Wire Central Strength Member

Fiber optic cables are used in many indoor applications, including plenum areas. To meet National Electrical Code (NEC) requirements for plenum areas, they must have a central strength member that resists bending. A steel wire is a common choice for this purpose, but alternatives such as aramid yarns are also being explored.

The steel wire is typically located in the center of the cable, surrounded by layers of protective materials. This combination of materials provides excellent tensile strength and crush resistance. The central strength member also helps to prevent damage caused by lateral pressure.

GYTY53 is a multi-mode outdoor fiber cable with a single or two steel wire central strength members, corrugated steel tape armoring and double PE sheath. It is suitable for duct and direct burial application. It can be supplied with a variety of core counts from 2 to 288. Special tube filling compound and water blocking jelly are also included, which protect the optical fibers and prevent the occurrence of water leakage. The central strength member and sheath are also insulated with a layer of aluminum-polyethylene lamination.
