Direct burial armored fiber optic cable stranded multi-tubes metal fiber cable GYTY53
GYTY53 direct burial optical fiber cable, Optical fibers are housed in loose tubes that made of high-modulus plastic and filled with tube filling compound. The tubes (and fillers) are stranded around a central strength member to form a cable core. The core is protected with water blocking tape ,a layer of inner PE sheath and corrugated steel tape. Then another layer outer PE sheath is extruded.
GYTY53 is a type of loose-tube, stranded, steel-tape armored, polyethylene-sheathed optical fiber cable. It is primarily designed for direct-burial installation and is suitable for long-distance and inter-office communications. It offers excellent resistance to lateral pressure, moisture, and rodent damage. Typically available with a fiber count ranging from 2 to 144, it can be configured with either single-mode or multi-mode optical fibers, depending on specific project requirements.

What do the model designations mean?
GY: Outdoor optical fiber cable for telecommunications.
T: Stranded loose-tube structure.
Y: Polyethylene (PE) sheath.
53: Dual-layer protective structure-consisting of an inner polyethylene sheath, followed by an armor layer of longitudinally applied corrugated steel tape, and finished with an extruded outer polyethylene sheath-designed primarily to enhance lateral crush resistance and provide protection against rodents.

Suitable Deployment Scenarios
Direct Burial: Can be buried directly in the ground; offers strong resistance against rodents and lateral pressure, making it suitable for areas with typical soil conditions.
Conduit or Aerial Installation: Can also be used in these configurations, though direct burial is the most common application.
Primary Use Cases: Long-haul telecommunications, inter-office (exchange-to-exchange) communications, and outdoor transmission lines.
Key advantage
The core advantage of the GYTY53 optical cable lies in its dual-layer sheath and steel-tape armor, which provide robust resistance against compression, rodent damage, and moisture-making it exceptionally well-suited for direct-burial and underground applications.
Excellent Crush Resistance
Featuring a longitudinally applied steel-tape armor combined with a dual polyethylene sheath, the cable can withstand short-term lateral pressure of up to 3000 N/100 mm, ensuring it remains undamaged even when subjected to the weight of heavy vehicles.
01
Protection Against Rodents and Mechanical Damage
The steel-tape armor layer effectively prevents damage from rodents, making the cable ideal for complex environments such as outdoor fields or underground installations.
02
Water and Moisture Resistance
The cable core is filled with a water-blocking compound, providing full-section water resistance, which makes it suitable for damp conditions and direct-burial environments.
03
Strong Environmental Adaptability
The cable operates effectively within a temperature range of approximately -40°C to +70°C and supports various installation methods, including direct burial, duct installation, and aerial deployment.
04
Stable Transmission Performance
Utilizing a stranded-core (loose-tube) design, the cable ensures precise control over excess fiber length, resulting in minimal additional attenuation after the cabling process.
