Fiber Optic Cable – GYTA53
Direct buried fiber optic cable is constructed with multiple layers of armor to resist the mechanical stresses and impact damage associated with underground installation. This type of fiber cable can be difficult to install and requires periodic inspections to prevent accidental disturbances during excavation and repairs.
This armored outdoor fiber cable is designed for direct burial installations, allowing you to save on the cost of conduit and pipeline construction. It features a steel tape armor, an internal LAP moisture barrier and double PE sheath.
Loose Tube Stranding Technology
Loose tube optical cable has been the dominant fiber optic cable design deployed in campus backbones for more than 25 years. This cable family has also emerged as a major choice for building backbones where riser or plenum flame ratings are required. Loose tube cables provide exceptional and reliable mechanical, environmental, and optical performance that has not been matched by other cable designs or media types.
Optical fibers, singlemode/multimode, are sheathed in loose tubes of high modulus plastic and filled with tube filling compound. A steel wire, sometimes sheathed with polyethylene (PE) for cable with high fiber count, locates in the center of core as a metallic strength member. The tubes and fillers are stranded around the strength member to form a compact and circular cable core. An Aluminum Polyethylene Laminate(APL) is applied over the core which is then filled with a water blocking filler and completed with a thin PE inner sheath.
Loose tube cables provide stable and highly reliable optical transmission performance over a wide temperature range. They offer the best protection for optical fibers under high pulling tensions and can be easily protected from moisture with water-blocking gel. They are the best cable type for outside plant trunks because they allow for quick splicing and installation, and they can accommodate higher cable counts than tight buffered cables without significant loss.
Corrugated Steel Tape Armor
GYTA53 optical fiber cable is a type of outdoor-rated, direct burial fiber cable. Its steel tape armoring provides enhanced protection against rodent bites and moisture. It also offers good crush resistance and UV radiation gyta53-fiber-optic-cable-direct-buried resistance. This product is often used in harsh environments and situations that require extra protection.
The cable is constructed with a metal wire central strength member, a special tube filling compound, and a corrugated steel tape armor. This design ensures the cable can withstand external mechanical loads. The steel wire also helps protect the optical fibers from corrosion. In addition, the core is filled with a special water-blocking jelly to prevent the ingress of moisture and dirt.
Steel tape armor is a longitudinally ribbed metal wire that offers both flexibility and high tensile strength. It is usually used with direct buried cables and other applications that need increased physical stress protection. It is an ideal choice for direct buried applications in areas with rocky soils and other environmental factors that can damage the cable.
The cable is also covered by a double PE sheath, which provides additional protection from external forces and environmental conditions. The sheath is also resistant to UV radiation, making it an excellent choice for outdoor installations. The tight construction of the cable also prevents moisture ingress, making it suitable for direct burial and underground ducting.
Double PE Sheath
GYTA53 fiber optic cable is designed for direct burial and outdoor use. Its steel tape armor provides robust protection against physical damage, making it ideal for challenging environments. The cable also features an internal LAP moisture barrier and a PE outer sheath, which further protects it from environmental factors.
The cable’s core structure involves sheathing 250mm optical fiber in a loose tube made of high modulus plastic and filled with a waterproof compound. A metal strength member is placed in the center of the core, while the loose tubes and filler rope are twisted around it to form a compact and round cable core. The gaps in the core are then filled with water blocking fillers. The core is then covered with a layer of aluminum polyethylene laminate and sheathed with a thin PE inner sheath.
The cable’s double sheath makes it suitable for installation in harsh environments where expected mechanical impact is high, such as direct buried applications. It is also suitable for installations in ducts where rodent resistance and moisture resistance are important considerations. Its loose tube stranding technology helps the cable mpo-harness-cables have good secondary excess length, which enhances its strain performance. The internal steel tape longitudinal groove reinforcement and the PE sheath provide excellent crush resistance and abrasion resistance. The internal aluminum polyethylene laminate (LAP) sheath provides longitudinal moisture protection, ensuring good environmental adaptability.
Water Blocking Structure
The water blocking structure of gyta53-fiber-optic-cable-direct-buried is very important, because it prevents the penetration of water into cable conductors. If the penetration happens, the water can travel longitudinally along the cables and damage any equipment that they connect to. Therefore, many outdoor fiber optic cables use a wet or dry water-blocking technology to prevent this from happening. Typically, this involves wrapping the inner cable components with an absorbent layer of a material that swells up when it gets wet. This has been estimated to double the lifespan of a cable that is used in wet environments.
Many companies have developed different types of water-blocking materials that can be used in these cables. Known examples of these include water blocking tape and water blocking yarn. These products are easy to manufacture and offer a high level of performance. They are also relatively inexpensive and can be easily produced on an industrial scale.
Another type of water-blocking technology that is popular in some markets is the use of super-absorbent powder (SAP) infused into cable thread or other cable elements. When SAP is exposed to moisture, it expands and fills possible pathways for water intrusion into the cables. This has been shown to be a very effective method of preventing water migration in cables, and it can eliminate the need for gels or oils in some cases.
