The requirements of the integrated wiring system for the optical cable
What are the requirements of the integrated wiring system for the optical cable? In the integrated wiring system, the optical cable in the vertical system is lifted between floors, the application in the narrow space of the communication cabinet in the horizontal system and the application of optical fiber to the desktop, and the communication application that passes through the high-voltage air-filled space. Indoor optical cables have different requirements.
Due to the special indoor environment, indoor optical cables must meet the requirements of toxicity, corrosiveness and low smoke in the standard while maintaining very good flame retardancy, mechanical properties and optical transmission properties. Therefore, it is necessary to be extremely cautious in the selection of indoor optical cables.
Integrated wiring optical cable
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 carrying out integrated wiring, two types of optical cables, vertical lift optical cable and rodent-proof optical cable, are generally used.
The vertical lift optical cable is to provide the connection between the entrance equipment, equipment room or computer room and communication cabinets on different floors after the optical cable enters the building, 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.
The anti-rodent optical cable is a single-core or multi-core tight-buffered optical cable protected by a stainless steel hose. It 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.
