What are the requirements for indoor optical cable wiring on optical cables? Indoor optical cables mostly use tight-buffered optical fibers or single-core cables as the basic unit, reinforced with aramid yarn, 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 exhibits good compression and bending resistance when it is terminated; good flexibility and toughness, small bending radius; very Good environmental protection improves the service life of optical fiber.
As a transmission medium of integrated wiring system engineering, optical cable has a wider range of applications and continues to meet people's needs for information and communication networks. Due to the special indoor environment, indoor optical cables must also meet the standards for toxicity, corrosion, and low smoke while maintaining very good flame retardancy, mechanical properties, and optical transmission properties. The following will tell you how optical cables meet the needs of indoor integrated wiring.
In the integrated wiring system, the floor-to-floor lifting of optical cables in the vertical system, the application of communication cabinets in the narrow space of the horizontal system and the application of fiber to the desktop, and the communication applications passing through the high-voltage inflatable space all put forward different requirements for indoor optical cables. Therefore, it is necessary to be extremely cautious in the selection of indoor optical cables.
Optical cable selection skills
At present, most indoor optical cables use tight-buffered optical fibers or single-core cables as the basic unit, reinforced with 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 exhibits good compression and bending resistance when it is terminated; good flexibility and toughness, small bending radius; very Good environmental protection improves the service life of optical fiber.
Tight-buffered fiber also has excellent moisture-proof function; the tight-buffered buffer layer is easily stripped to the fiber core; it is compatible with all standard connectors; it simplifies the termination procedure and reduces the termination cost. The tight-buffer fiber design and flame-retardant or non-flame-retardant jacket make the indoor fiber optic cable fully meet the requirements of indoor safety applications. Therefore, indoor high-performance communication transmission applications generally use indoor optical cables designed with tight-buffered optical fibers.
We generally use two types of optical cables when performing integrated wiring: vertical lifting optical cables and anti-rat optical cables.
Vertical lifting of 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 cabinet 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, optical cables need to withstand greater tensile forces.
Rodent-proof optical cable: single-core or multi-core tight-buffered optical fiber cable protected by stainless steel hose, which has the characteristics of strong lateral pressure resistance, bending resistance, high tensile strength, and excellent rodent-proof performance. It can be used in occasions where trampling occurs, such as laying under carpets or occasions where frequent bending is required in a limited space or there is rodent infestation.
