How to choose optical cable for indoor integrated wiring

As a transmission medium in integrated wiring system engineering, optical cable has a wider and wider range of applications, and is constantly meeting people's needs for information and communication networks. However, due to the special indoor environment, how to choose optical cables for indoor integrated wiring has become a knowledge that we need to understand clearly.

How to choose optical cable for indoor integrated wiring

In the integrated wiring system, the floor-to-floor lifting of the optical cable in the vertical system, the narrow space application of the communication cabinet in the horizontal system, the application of optical fiber to the desktop, and the communication application that passes through the high-pressure air-filled space all put forward different requirements for the indoor optical cable. Therefore, it is necessary to be extremely cautious in the selection of indoor optical cables.

At present, most of the indoor optical cables use tight-buffered optical fibers or single-core cables as the basic unit, reinforced by aramid yarns, and soft optical cables with flame-retardant or non-flammable sheaths. Its advantage is that the tight sleeve is integrated with the optical fiber to provide good mechanical protection, so that the optical fiber shows good compression and bending resistance during termination; good flexibility and toughness, small bending radius; very good Good environmental protection improves the service life of the optical fiber.

The tight-buffered fiber also has excellent moisture resistance; the tight-buffered buffer layer is easily stripped to the fiber core; it is compatible with all standard types of connectors; it simplifies the termination procedure and reduces termination costs. The tight-buffered fiber design and flame-retardant or non-flammable jacket make the indoor cable fully compatible with indoor safety applications. Therefore, indoor optical cables with tight-buffered optical fiber design are generally used in indoor high-performance communication transmission applications.

When conducting integrated wiring, we generally use two types of optical cables: vertical lift optical cables and rodent-proof optical cables.

Vertical lift optical cable: After the optical cable enters the building, it is necessary to provide the connection between the entrance equipment, equipment room or computer room and the communication cabinets on different floors, which is called "vertical wiring system". At this time, the optical cables are mostly located in the vertical pipes of the shafts between floors. For this reason, the fiber optic cable needs to withstand greater tensile forces.

Anti-rat optical cable: single-core or multi-core tight-buffered optical cable protected by stainless steel hose, which has the characteristics of strong lateral pressure resistance, bending resistance, high tensile strength, and excellent anti-rat performance. It can be used in situations where trampling occurs, such as under carpets or where limited space requires frequent bending or rodent infestation.
