The technique of selecting leather fiber optic cable in indoor wiring
As a transmission medium of integrated cabling system engineering, the application range of leather fiber Optic Cable is more and more extensive, and it constantly meets people's demand for information communication network. Due to the special indoor environment, indoor optical cables maintain very good flame retardant, mechanical properties and light transmission characteristics at the same time, but also meet the requirements of the standard for toxicity, corrosion and low smoke. So how do optical cables meet the needs of indoor cabling?
In the integrated cabling system, the elevator between floors of the cable in the vertical system, the application of the narrow space of the communication cabinet in the horizontal system and the application of the optical fiber to the desktop, and the communication application through the high-voltage inflatable space have put forward different requirements for the Indoor Cable. Therefore, the choice of indoor optical cable is to be extremely cautious.
At present, most of the indoor optical cables use tight-sheath optical fiber or single-core cable as the basic unit, arnylon yarn reinforcement, the use of flame retardant or non-delay sheath of soft optical cables. Its advantage is that the tight sleeve is combined with the optical fiber to provide good mechanical protection, so that the optical fiber shows good compression and bending resistance when terminated; Good flexibility and toughness, small bending radius; Good environmental protection, improve the service life of optical fiber.
The tight-jacketed fiber also has excellent moisture resistance; The tight cushioning layer is easy to peel into the optical fiber core; Compatible with all standard connectors; Simplify the termination procedure and reduce the termination cost. The tight-fitting fiber design and flame-retardant or non-flame-retardant sheathing enable indoor cables to fully meet the requirements of indoor safety applications. Therefore, indoor high-performance communication transmission applications generally use tight jacket optical fiber design indoor optical cable.
In the integrated wiring, we generally use two kinds of optical cables: vertical lifting optical cables and rat-proof optical cables. After the cable enters the building, it is necessary to provide the connection between the entrance equipment, equipment room or computer room and the communication cabinet on different floors, which is called the "vertical wiring system".
