FTTH arcuate de fíos de aceiro de aceiro de baixar

FTTH introduces Cable óptica de fibras to be laid at the user end, used to connect the terminals of the backbone Cable óptica de fibras to the user's building or residence. Its characteristics are small volume, few fiber roots, and a support span of about 80m. Commonly used in overhead and pipeline construction, not commonly found in underground or buried installations.
There are mainly indoor and outdoor Cable óptica de fibra entries. The most common outdoor entry cable has a mini flat 8-shaped structure; The most common indoor reinforcement is two parallel steel wires or fiberglass reinforcement bars, with a Cable óptica de fibra in the middle.

Character of fiber drop cable

• Small size, light weight, good bending;

• Simple structure, simple installation and convenient construction;

• Two parallel glass fiber reinforced plastic or metal reinforced materials can provide good compression resistance and protect the optical fiber;

• Unique groove design, easy to peel off, easy to connect, simplify installation and maintenance;

• Low-smoke halogen-free polyethylene sheath

Application of Fiber Caba de solta

1. Interno users

Interno optical cables mainly include 1F, 2F, and 4F.

Household optical cables should use 1F;

Enterprise users should use 2-4F optical cable design.

There are two types of household optical cables: FRP reinforcement and steel wire reinforcement. Taking into account factors such as lightning protection and strong current interference, FRP reinforcement should be used indoors.

2.Wire laying in the building

Wiring in buildings Horizontal wiring does not have high requirements for optical cables, while vertical wiring requires optical cables to have a certain tensile strength, as well as flame retardant requirements. Therefore, the tensile strength of optical cables must be considered.

3.Overhead self-supporting wire laying

The figure-8 self-supporting optical cable adds a steel wire suspension on the optical cable, offers Máis. tensile strength, and can be laid overhead. It is suitable for outdoor overhead wiring to enter the indoor wiring environment. Before fixing the steel hanging wire on the special bracket, first cut off the steel wire, strip off the steel wire cable on the remaining optical cable.

4.Duct wire laying

Duct optical cables and self-supporting "8" optical cables are both indoor and outdoor integrated optical cables, which can adapt to indoor and outdoor environments, and are suitable for FTTH drop cable from outside to indoor. Because the outer sheath, reinforcement, and water-blocking materials are added on the drop optical fiber cable, the Duct optical cable has higher hardness and waterproof performance and is suitable for outdoor duct laying.

What are drop cables used for?

Internet service providers connect directly to service equipment by using optical cables. Usually contains no Máis. than 12 fibers. The following four Cable óptica de fibra designs are the most commonly used today.

FTTH optical cable (known as drop cable). The drop flat cable contains 1 to 4 coated ptical fibers. The coating of the optical fiber can be colored, blue, orange, green, brown, gray, white, red, black, yellow, purple, pink or light green in compliance with the requirements.

The single-fiber use natural color. The reinforcement in the cable can be steel wire , or FRP reinforcement. The sheath of the drop cable should be made of low-smoke and zero-halogen materials to meet environmental protection and flame-retardant indoor wiring requirements. Fóra FTTH drop cables should meet the water-blocking requirements.
