GYTY
Optical Fiber Cable Non Armored Stranded
Loose Tube Duct Installation
Through GYTY fiber optic cable, primarily intended for outdoor application, telecommunication operators can transmit optical signals over long distances. These cables are made of a structure termed GYTY, in which these optical fibers are housed in loose tubes filled with a gel, which is water-blocking, and stranded around a central strength member. Finally, the outer polyethylene (PE) layer offers mechanical protection. Noteworthy is the "Y" in the abbreviation, which denotes the use of PE sheath, and the "T" is usually for design with a filled loose tube, as such, moisture penetration is not a problem.
If the cable is not armored, GYTY cables are non-metallic, light, and can withstand various harsh environmental conditions, hence making them perfect for installation in the ground, in ducts, or aerial use with self-support structures.
1. Loose Tube: thermoplastic material, containing opticalfibres and water blocking yarm.
2. Central Strength Mlember: glass fibre reinforced plasticrod (GFRP) coated with PE when needed.
3. Filler Elements: thermoplastic rods.
4. Longitudinal Water Blocking Material: Water blocking tape.
5. Armor: corrugated steel tape.
6. Outer Sheath: black polyethylene
High Tensile Strength: Because of the internal strength member, the cable is tough when under high pulling forces while installing.
Excellent Water Resistance: Compounds and materials that block water are of high caliber when it comes to providing moisture protection for the cables, which result in longer life spans.
UV Resistance: The polyethylene outer sheath insulates with UV protection for outdoor usage.
Stable Optical Properties: Many fibers are loose where the internal radius will permit fibers to sustain low attenuation and have the capability to transmit high bandwidth under mechanical load or temperature instability.
Lightweight and Flexible: Ideal for haulage, handling, and installation ease.
Rodent Resistance: The company can also design exotic rodent-repellent designs for affected areas.
Long-distance backbone communication networks.
Campus and inter-building backbone networks, as well as metropolitan area networks (MANs).
Communication cables installed underground in open trenches.
Cable duct installations.
Installation over the aerial lines with proper support.
Avoid Excessive Bending: Fiber installation do not perform the bending at any instance; otherwise, the damage to the fiber is certain.
Control Tension: To avoid damage to the cable, the force exerted while pulling on the cable should not be more than the maximum tensile strength.
Protect Cable Ends: Moisture ingress during storage and installation can be prevented by sealing the cable ends while storing and installing.
Storage and Handling: Store the cable in a cool, shady area away from sunlight and do not leave the cable on the reel for too long.
